Can you use Rock Catching to Catch a Battering Blast


Rules Questions


Rock Catching (Ex)
The creature (which must be of at least Large size) can catch Small, Medium, or Large rocks (or projectiles of similar shape). Once per round, a creature that would normally be hit by a rock can make a Reflex save to catch it as a free action. The DC is 15 for a Small rock, 20 for a Medium one, and 25 for a Large one. (If the projectile provides a magical bonus on attack rolls, the DC increases by that amount.) The creature must be aware of the attack in order to make a rock catching attempt.

Battering Blast
You hurl a fist-sized ball of force resembling a sphere of spikes to ram a designated creature or object. You must succeed on a ranged touch attack to strike your target. On a successful hit, you deal 1d6 points of force damage per two caster levels (maximum 5d6). For every 5 caster levels you possess beyond 5th, you gain a second ball of force.

I think the two relevant questions are
1) Does a sphere of spikes = rocks (or projectiles of similar shape)
2) Is a fist-sized ball smaller than Small, Medium, or Large rocks

I think the answer is 1) Yes, 2) No, but want to check what others think.

Thanks


1) Yes, if there was an actual spiked ball being throw it could be caught.

2) Fist sized for a medium/small creature should be around diminutive sized actually.

3) And no, battering blast creates a force effect, not something subject to Rock Catching. You need a feat that actually lets you counter spells like Cut From the Air to block a battering blast. Though you could use Rock Catching to block a projectile from Telekinesis since that is literally throwing a real object.

Trying to catch the force effect is like trying to block fire arrows with your hands. You're basically volunteering to be hit.

I disagree with Meirril. Force effects are not inherently damaging to handle- you can rub your face on a Wall of Force without being hurt, unlike a Wall of Fire. They're temporary pseudo-matter, and when they deal damage, it's because they're sharpened or moving at high speed. So I'd say you can catch a battering blast just fine.

On a more meta level, taxing mundanes to be able to interact with magic is not the direction Pathfinder needs to move in. We already have too much of that. The man paid his feat to catch balls; let him catch the magic ball.

Thrown rocks do bludgoning damage. Walls of Fire do fire damage. Magic Missiles do force damage. So does Battering Blast.

Spells have flavor text to 'explain' what they do. Most of the time when you're talking about rules interactions, you ignore that. You do what the spell says.

Just like with wall of fire, on one side you take fire damage from just approaching it. On the other side, you can almost touch the wall and take no damage. Why does the wall of fire act differently than a real fire? Because the rules say so.

If we follow InvisiblePink's suggestion then every monk and almost every martial that can will take deflect arrow so they can be virtually immune to targeted spells, and the players will ask questions like "if I deflect a fireball, shouldn't it just disappear?" or "What if I catch it in a bucket of water?"

'Logic' only goes so far in a game. Lets just try to follow the rules.

Deflect Arrows says you can't deflect magic projectiles, so you can't. Rock Catching says you can catch rock-shaped projectiles, so you can catch rock-shaped projectiles even if they happen to be magic. Nowhere does it say they need to deal bludgeoning damage.

There's your rules for you. No logic required.

That spell does not throw rocks, that's flavor text flat-out.

Besides, it doesn's specify how large the attack is, similarly the "ball" disappears after it's thrown and doesn't exist for all intents and purposes after the attack.

Battering Blast does Force damage, and the spell even describes it as "a ball of force" so no Rock Catching doesn't help at all.

It's a "projectile of similar shape" to a rock. If you took a round rock and glued spikes to it, Rock Catching would still help you catch that.

Force objects are solid while they exist, unless you believe that I can simply walk through a Wall of Force or Emergency Force Sphere. You can catch it since it's solid for long enough to hit you, and then it disappears in your hand.


What the hell even is the shape of a rock? Rocks don't have to be round, flat, smooth, jagged, thin, thick, or any of the above. You might as well say you can catch a ballista bolt because spikey rocks exist and that's basically in the shape of a bolt.


I'd rule the shape of a rock as being "vaguely round". While technically a rock can be any shape, rocks that are suitable for throwing tend to be roundish. I'd let you catch a Goblin Skull Bomb, but not a shuriken or an arrow.

if the spell was force effect that deal B damage i might have agreed if it was big enough. but seeing that it deal force damage which is a kind of energy i say it's not solid enough to catch, like any other energy attack if you tried to catch it (fire or cold or acid balls would hurt your hand. so does this. )
you seem to only think of force effects as craerting force fields taht are hard (like mage armor and force wall) but they come in two variants. some hard. some are energy (think of it as liquid force? numerios small paricales of energy) magic missile for example.(it's not solid and deal P damage, it's energy and deal force energy damage)

No dude, it doesn't matter if it's even rock shaped, the fact it the attack isn't a Projectile attack, neither does it actually throw a "Small, Medium, or Large" Rock at all.

This just flat out doesn't work on pretty much any level.

Rock Catching pretty clearly is meant to function against you know.. actual ROCKS or other physical objects that require a specific Size Category (To which their damage is tied) to function. The spell has NONE of those things, the only supporting flavor here is just that... flavor, not mechanics.


Oh you don't need to rule that a rock suitable for throwing is roundish, rules actually do describe what a throwable "rock" looks like under Rock Throwing

"A rock is any large, bulky, and relatively regularly shaped object made of any material with a hardness of at least 5."

Balista bolts are large, bulky, and relatively regularly shaped with a hardness of 5+ so clearly it is a rock and catchable along with virtually anything else that isn't just a chaotic blob of material.

Regular and regular shape are mathematical terms describing objects that have sides/faces that are equilateral and equiangular. Spherish rocks are roughly regular. Many boxes are roughly regular, but generally won't have the hardness (unless they're made of stone). A ball with spikes covering it is roughly regular. Ballista bolts do not come close.

Regular also has a dictonary definition of "arranged in or constituting a constant or definite pattern, especially with the same space between individual instances" and a ballista bolt definitely has a constant/definite pattern.

You tell me whether the rulebook means regular in the dictionary or mathematical sense although I'll wager a guess the devs were not writing that particular rule with a copy of their old high school math textbook open to the glossary.

Your dictionary definition is talking about patterns and the arrangement of objects, so it doesn't really apply to the shape of a single object.


For whatever my opinion is worth, I don't think that Rock Catching ability would work on it.

Stephen I recommend asking your GM to make a ruling, or if you're the GM to make a ruling based on your gut.

My gut said "nah", yours might say something else.

I honestly want to know what elementary school you were going to where geometry was on the curriculum.

Either way, if you're telling me a spikey ball (which per your definition is about as irregular as you can possibly get) then I'm not seeing how a giant spike (aka a cone) is beyond the pale. Hell, they don't even have those pesky bits of irregular fletching (not that it matters since random spikes aren't enough to get past "roughly" evidently, so a few extra triangles on the end shouldn't either).

Hurling something is throwing it.
So yes, something, a ball of force, is been thrown at the target by the caster.

I would note that you can block/catch fire arrows with your hands in game, so using that as an analogy to say you can't do it doesn't really support your argument. :-)

Among other things that helps me decide how much CR increase I'm dealing with if any.

I was thinking I would make the DC to catch +5 for every size below Small, and probably another +5 for spells that are objects that can be caught.So a Tiny spike sphere of force would be DC 30 Reflex to catch.

Correction - Diminutive - wrong word, right calculation. :-)


zza ni, can you give me an example of a force spell that deals damage without relying on striking the target at speed, being sharp, or otherwise having a physical mechanism of injury?

My understanding of force effects is that they are essentially momentum or "substance" that happens to not have physical mass. But if there's an example of a force effect that causes harm merely by touching it without a physical mechanism of injury, similar to how cold or poison might, then my understanding must be wrong.

Yes, I learnt what squares, circles and octagons are in elementary, and an irregular octagon looks different than a regular octagon.

A sphere with many protruding cones whose tips are centered with the sphere approaches that of a star-shaped polygon. It has many faces that are the same shape and have roughly spherical symmetry. Perhaps I'm thinking of the ideal case where the cylinders are equidistant from each other and bleeding that into a nonideal case.

A single cone isn't regular. Its two faces are wildly different from each other in both shape and angle. A single cone attached to a cylinder isn't any better.

Shadow Lodge

I think Rock Catching relies on the fact that rocks are bulky, and wasn't intended on being useful for objects smaller than Small. If you've already decided that it can be used to catch Diminutive objects, can it be used on Fine spheres like bullets? This is my larger issue with your question.

As a GM, I'm fine with the ability working on spells using rock-shaped projectiles, and this spell in particular given that you've already extended Rock Catching's usefulness past Small.

Battering Blast's projectiles are Small-rock-sized. A "Small" rock is a rock that is appropriately-sized for throwing by a Small creature, not a rock that is the size of a halfling. Golarion would be a funny world if Rock Catching allowed you to catch a thrown boulder the size of a Buick, which is what your interpretation logically suggests.

IP; You've got it backwards man. The Rocks are not "Small-Large Weapons" they're X size OBJECTS in the same way that literally any other object is.

If you're throwing a Medium Sized Rock, you're throwing a Human Sized Rock, not a "Rock that's sized for a medium creature to throw."

Rock Throwing wrote:
... A creature can hurl rocks up to two categories smaller than its size; for example, a Large hill giant can hurl Small rocks. A “rock” is any large, bulky, and relatively regularly shaped object made of any material with a hardness of at least 5.

You're either accidentally or willingly leaving out the important parts of the text. A Creature MUST be 2xCategories Larger than a Rock of any given size to throw it...


Huh. I guess you're correct.

This does leave the peculiarity that you can, apparently, catch (but not throw) a rock that's your own size if you're Large. But that's not the weirdest thing to happen in Pathfinder.

Another way to go about it is to ask your players what they think is fair, and ask them not to metagame too much about the question.

At the end of the day the goal is for everyone to have fun. If your players will have more fun one way then you might run it that way. Or you might want it to be more challenging, so maybe you give an enemy a special version of rock catching that you say can do this.

As far as how much this affects CR rating....unless you players just love throwing this specific spell against the enemy to the exclusion of everything else I would say that allowing it to work is probably not worth increasing the effective CR at all.


No you cant catch the battering blast anymore than one could feasibly catch a fireball or a hold person spell.


I'd say no.

It's spikey and too small ... at minimum I agree I'd up the DC to do so.

And even successfully catching it still involves the Bull Rush. The flavor text makes it fairly clear there is a lot of impact behind the attack. It can still destroy a door or "obstacle" even if the damage doesn't from the sheer power behind it.

i kinda already did..magic missile is force spell. deal force energy damage. has nothing in it saying anything about "striking the target at speed, being sharp, or otherwise having a physical mechanism of injury"

-your welcome

btw it does say it 'darts' to the target but even acid arrow has the words "speeds to it's target" so how fast it goes is not any factor.(i think the magic missile flavor is more to point out it's unavoidable)

as i said above. force spells have two common ways they appear. as force energy damage which follow all energy damage rules (such as magic missile spell) and solid force objects that deal physical damage (such as force sword spell)


Magic Missile does strike the target at speed. Because it's a projectile. It might derive its damage from its abstract force-energy rather than the kinetic impact, but it also makes sense if we assume that it's just guided magical "pseudo-matter" moving pretty fast, and therefore proves nothing either way.

I'm asking for a spell like a force Wall of Fire or Noxious Cloud.

That totally ignores the special properties of force damage. Insubstantial creatures are usually affected by force damage without any damage reduction. DR normally has no effect on force damage, or any other energy damage. Force damage is specifically a type of energy damage.

If you need convincing, look at 10 different force effects. There will be a large discrepancy between what they do. The designers of the different spells will not agree with each other. Some imagine that force effects are sharp cutting effects. Some imagine they make nearly invincible barriers. Others that it can mimic natural attacks. Some think they mimic physical objects. And Magic Missile doesn't think the fluff was important enough to describe how it damages things. And Gravity based energy weapons do force damage. No substance is created, its just a beam of gravity. Does force damage.

Yes. I think a bullet would count as Fine IIRC, so under the idea I'm looking at that would be +15 to the DC - Reflex 30 DC to catch a single bullet per round, or 2 if you have the right magic glove doesn't seem to unbalanced.

The Giants concerned are a house modified Stone Giant, but I think it probably balanced regardless.


You cannot use Rock Catching to catch a Battering Blast. If it was meant to, it would say so in the spell description and/or the feat description.

The Giants concerned are a new superior race of Stone Giants. A Small Military Unit the opposition has and that the players would like to hire if they can pry them away from their existing contract - probably by killing the current employer. :-)

So yes, regarding catching Magic Force objects can easily be attributed to special magic powers (which they already have in regard to throwing stuff).

As for Battering Blast -
One PC with Spell Perfection uses Battering Blasts with a combination of Intensified, Empowered and Quickened - 3 Balls each time he casts it.
So yes, he thrashes the hell out of the spell (which is the best arcane direct damage spell IMHO) and at best it only stops one ball, or two if they have the Gauntlet/Glove that gives you Rock Catching if you don't have the ability.
He loves using it with Create Pit behind target followed by quickened Battering Blast and into the Pit the target goes. :-(

Not really.

Rock Catching predates Battering Blast.
But as someone has already mentioned the comparative ability Deflect Arrows specifically says you can deflect ranged attacks, not just arrows, but not Magic generated ranged attacks. Rock Catching does not have any such restrictions.

Spells don't generally try and cover every ability that could interact with them. If they did the spells would require several times as much space to write, and a lot more work.

Using Rock Catching to catch a Battering Blast is a non-sequitur. Rock Catching is from the Universal Monster Rules, so if you're going to suggest that Stone Giants and Hill Giants are proficient at catching Magic Force Balls because they're also proficient at catching rocks, then I dunno what to say other than that I seriously disagree.

Battering Blasts are ranged touch attacks, so as soon as it touches you, you get damaged. The only way to avoid this is to successfully dodge out of the way. It's actually impossible to "catch" them.

I'm not saying there aren't valid arguments against been able to use Catch Rocks (and other objects - it's not rocks only) and they've been raised, but the argument that it's not specifically mention in the ability or the spell isn't one of those valid objections IMO given the way the rules are written.

As for Catching/Deflecting stuff - the Rules Team have made clear that if you use deflecting type abilities (which included Deflect/snatch and return arrows) you are treated as not been hit and avoid any effects. This includes Touch Attacks (specifically mentioned by the rules people).
Therefore it's perfectly reasonable to say that if something allows you to deflect/catch a ranged Touch Attack you do indeed avoid the consequences. It does not detonate regardless.

It's still not possible to "catch" a battering blast. It detonates if it touches you at all, including if you "catch" it. It's like saying that a cactus can "catch" a water balloon.

Actually nobody has brought up the best argument for why you can't do it. Rock Catching works vs Small/Medium/Large projectiles. A battering blast and just about every thrown projectile an adventurer would use is too small for Rock Catching to work.

Battering Blast is about "the size of the caster's fist", which is diminutive by my estimation. Even if you generously pump it up to tiny that is still outside of Rock Catching's range of allowed projectiles.

Rock Catching is meant for giant on giant engagements, not to stop all those pesky adventurers from using ranged attacks.

I think OP wants to houserule that you can do smaller projectiles, but that is a houserule.

no

No, you are confusing it with Fireball which says -

"A glowing, pea-sized bead streaks from the pointing digit and, unless it impacts upon a material body or solid barrier prior to attaining the prescribed range, blossoms into the fireball at that point. An early impact results in an early detonation. If you attempt to send the bead through a narrow passage, such as through an arrow slit, you must “hit” the opening with a ranged touch attack, or else the bead strikes the barrier and detonates prematurely."

There is no such language for Battering Blast.
Indeed all the language indicates that the Battering Blast does not explode but stays intact Bullrushing targets after doing damage, including attempting a strength check to knock down a door target after doing damage to the Door.

-----------------------------

Battering Blast:
You hurl a fist-sized ball of force resembling a sphere of spikes to ram a designated creature or object. You must succeed on a ranged touch attack to strike your target. On a successful hit, you deal 1d6 points of force damage per two caster levels (maximum 5d6). For every 5 caster levels you possess beyond 5th, you gain a second ball of force.

A creature struck by any of these is subject to a bull rush attempt. The force has a Strength modifier equal to your Intelligence, Wisdom, or Charisma modifier (whichever is highest). The CMB for the force’s bull rush uses your caster level as its base attack bonus, adding the force’s Strength modifier and a +10 bonus for each additional blast directed against the same target. Each sphere of force makes its own separate bull rush attempt—if multiple spheres strike one target, you make multiple CMB checks but only take the highest result to determine success. If the bull rush succeeds, the force pushes the creature away from you in a straight line, and the creature must make a Reflex save or fall prone.

This spell pushes an unattended object struck by it 20 feet away from you, provided it weighs no more than 25 pounds per level (maximum 250 pounds). This spell cannot move creatures or objects beyond your range. Used on a door or other obstacle, the spell attempts a Strength check to destroy it if the sheer damage inflicted by the spell doesn’t do the job.

A creature can hurl rocks up to two categories smaller than its size; for example, a Large hill giant can hurl Small rocks.

That seems to indicate that it isn't a rock sized for a small creature, its a rock as large as a small creature! So yes, a fist sized ball for even a large creature is smaller than a small sized 'rock'.

If you want to push it to where creatures with this EX ability are throwing fist sized objects then that means medium creatures can't throw rocks larger than a pea, the fist size of a diminutive creature. Obviously that is the incorrect judgement.

That totally ignores the special properties of force damage. Insubstantial creatures are usually affected by force damage without any damage reduction. DR normally has no effect on force damage, or any other energy damage. Force damage is specifically a type of energy damage.

The way I interpret them, force effects are "kinetic energy or substance without real matter". They affect insubstantial creatures because whatever allows insubstantial creatures to phase through normal matter doesn't allow them to phase through the ideal "substance-ness" of force. It is "energy damage" in the same sense that kinetic force is a kind of energy. DR does not apply because it's a magically idealized form of kinetic energy.

If you need convincing, look at 10 different force effects. There will be a large discrepancy between what they do. The designers of the different spells will not agree with each other. Some imagine that force effects are sharp cutting effects. Some imagine they make nearly invincible barriers. Others that it can mimic natural attacks. Some think they mimic physical objects. And Magic Missile doesn't think the fluff was important enough to describe how it damages things. And Gravity based energy weapons do force damage. No substance is created, its just a beam of gravity. Does force damage.

Gravity-based energy weapons dealing force damage is something of a kludge in my view, but not wholly inconsistent either. It's, in effect, "momentum without matter" (please forgive me, physicists). But Battering Blast does rather explicitly create that idealized force-substance, and then launches it at the target at speed.

You haven't given me anything that would disprove or question my understanding of force effects; you've only given me things that one might choose to interpret as being against it, but which are equally explicable if one assumes my understanding instead.

It's still not possible to "catch" a battering blast. It detonates if it touches you at all, including if you "catch" it. It's like saying that a cactus can "catch" a water balloon.

Where in the spell description does it state that the projectile detonates at all? I've always pictured the spiked balls of force ramming into the target, then forcibly pushing them back with their remaining momentum.

The size argument is the only compelling argument I've seen against being able to do this. If you're willing to houserule that they can catch fist-sized objects (which I wouldn't do in my personal games), then I still believe it works.


The size thing is an interesting issue that is yet to be fully resolved. Would you allow this giant to catch a sling stone hurled by a halfling? Is that item a small stone because it was used as a weapon by a small creature? Or is it a diminuitive stone because that's literally the size of the object?

Is it reasonable for a giant to catch something this small? A battering blast is still big enough for him to see and notice, but at what point does it actually become cumbersome to catch? What if it were cast by a halfling, or a pixie? Imagine as a human using a rock-catching ability to try and grip and catch something the size of a BB coming your way.

I think that based on the size issue, this wouldn't be allowed. If the size of the force projectile were increased to actual small size then I think it would be back in consideration.

The stone is a Fine object, and he's already spent some of the thread explaining that he's okay with using Rock Catching on objects of this size.

No, you are confusing it with Fireball which says -

"A glowing, pea-sized bead streaks from the pointing digit and, unless it impacts upon a material body or solid barrier prior to attaining the prescribed range, blossoms into the fireball at that point.

If you attempt to send the bead through a narrow passage, such as through an arrow slit, you must “hit” the opening with a ranged touch attack, or else the bead strikes the barrier and detonates prematurely."

I'm not confusing anything. If there's anyone in this thread who's confused, it's you my friend. Battering Blast is Instantaneous duration, so it flies at your target at twice the speed of Gimme Ur Loot and blasts the target, sending them backwards with a successful Bull Rush attempt.

Here's the steps:
PC: "I'm casting Battering Blast"
DM: "Okay, make a Ranged Touch Attack"
PC: "I rolled a 17 to Touch"
DM: "That hits, roll for damage and your CMB to Bull Rush"

You'll notice that the spell doesn't say this:

the problem is the Battering Blast Evoc[frc] is a spell effect, not an actual object(like a rock). The same is true for a Phantasmal Steed or Force Sword. The description is essentially "flavor text" as you cannot give the Battering Blast to another character(as you can with Phantasmal Steed or Force Sword) and the spell is Instantaneous (once a roll to hit is rolled or calculated{GM dependent} even interrupts/immediates are over).
A target can't catch a Scorching Ray or a Fireball unless the intent is to lower their AC and accept the spell effect(aka auto hit) or origin of the effect.
A caster cannot take off Mage Armor or Shield (spell effects), only dismiss or end the spell.

There are some feat chains such as Deflect Arrows but those are rather specific about how they work.

As there is no text in Battering Blast about catching/deflecting/giving to others or Rock Throwing about spells, thus it is a firm "no" in RAW. It is also a contrary implementation/interpretation to some 40yrs of DnD play history.

It could be cute to do this in a home game but there would be serious repercussions to spellcasting in general.
I have seen this via a magic item in AD&D using GM caveat. It was a silly game that also had giant robot penguins and a pink pershing tank with bunny ears and a fluffy tail so the 25HD magic immune +5 vorpal bunny wouldn't attack it...

you have to remember that this is a game and the books are works of art, not a science text or mathematics textbook. The PF books are not consistent and contradict themselves at times. Less editing goes into non-core product lines.
Mostly the first paragraph in a new (post CRB) spell description is descriptive text to engage your imagination rather than give mechanical rules or effects in the game. It's a creative writing thing. So you have to do some careful parsing as to what are 'rules' and what is not (aka flavor text). You have to be mindful that it's a whole conversational english creative description and reading it too literally and over parsing things can land you in a heap o trouble. So it takes some balancing and what I would say is a common acceptable practice in play history.
