Casting light on an invisible target?


Rules Questions

1 to 50 of 234 << first < prev | 1 | 2 | 3 | 4 | 5 | next > last >>

A hag takes a 5' step away from someone and turns invisible. The party member assumes since she took a 5' step she didn't move further and casts light, holds the charge takes a 5' step and wants to release on the hag.

Does Total Concealment come into play here and make them make a touch attack with 505 miss?

If it hits, would it stick and cause the light source to follow her while invisible?


1) Light can only target objects. Hags are not objects. Therefore the situation has already failed.

2) However, if they did want to cast some spell in that square, then they would suffer the normal total concealment 50% miss chance.


Ok for argument purposes, let's say they want to touch the hag's garment. So they make a 50% check and pass. The garment would emit light as the hag moved around, even though she was still invisible?


"An invisible burning torch still gives off light, as does an invisible object with a light or similar spell cast upon it."

Grand Lodge

The way I read the invisibility and light rules, the effect is that of a light with no source. That means no shadows are pointing toward it, but it's just an increase of the ambient light.

If you wanted to take the time to suss out the edges of the light, you MIGHT be able to pinpoint the center. But I'd make you use a full round survival check DC20 to find an edge. I'd make you pick a direction to move, make your survival check as a second move action, and stop you (if you made your check) when you got to the edge. If you didn't reach the edge, or if you didn't make your check, you'd stop at the end of a movement. Remember, the light spell still has an effect in the second 20ft - it raises the light level one step from whatever it had been. So while mechanically there's a difference, it's not a bright bold line as seen by the characters. So you're basically trying to find the edge between normal light and dim light. If the surroundings are dim light, then you're looking for the 40ft border, since you now have 40ft of normal light.

But it wouldn't be impossible, and if two characters found edges, I'd let a third try to triangulate the location and lob and arrow or a bag of flour or something. But you'd better do it quickly, because my hag isn't stupid, and she can see what you are doing. She just might strip, leave the garment in the center of the room, and sneak quietly away! (Edit: at the very least she'd move.)

I will say, though, that it would be amusing to me to see a character with a light on himself walk away forever looking for the edge.

And since she gets invisibility at will, she'd naturally cast it on the garment after stripping but before dropping! There's no VSM component, so who's to know?

And that's when see invisibilty became a bad idea...


IMO, if you manage to tag someone with a light spell, they can be automatically pinpointed, unless they are in an area with a higher light level.

I understand what you're saying, but I don't think that's how the rules read:

Invisibility Spell Description wrote:

The creature or object touched becomes invisible. If the recipient is a creature carrying gear, that vanishes, too. If you cast the spell on someone else, neither you nor your allies can see the subject, unless you can normally see invisible things or you employ magic to do so.

Items dropped or put down by an invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature. Light, however, never becomes invisible, although a source of light can become so (thus, the effect is that of a light with no visible source). Any part of an item that the subject carries but that extends more than 10 feet from it becomes visible.

Of course, the subject is not magically silenced, and certain other conditions can render the recipient detectable (such as swimming in water or stepping in a puddle). If a check is required, a stationary invisible creature has a +40 bonus on its Stealth checks. This bonus is reduced to +20 if the creature is moving. The spell ends if the subject attacks any creature. For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe. Exactly who is a foe depends on the invisible character's perceptions. Actions directed at unattended objects do not break the spell. Causing harm indirectly is not an attack. Thus, an invisible being can open doors, talk, eat, climb stairs, summon monsters and have them attack, cut the ropes holding a rope bridge while enemies are on the bridge, remotely trigger traps, open a portcullis to release attack dogs, and so forth. If the subject attacks directly, however, it immediately becomes visible along with all its gear. Spells such as bless that specifically affect allies but not foes are not attacks for this purpose, even when they include foes in their area.

(Emphasis added to salient portion)

What exactly is light with no visible source? It sure as heck isn't a floating star in a particular square. Instead, I imagine a situation where the light seems to come from everywhere. Where the sources of light are so diffuse as to eliminate shadow. Think of being outside on a heavily overcast day. There aren't really any shadows, because the sun doesn't directly light the ground. The clouds disperse and diffuse the light, so that it doesn't really seem to come from anywhere, but instead just...is.


I think you're over-interpreting "light without a visible source".


1 person marked this as a favorite.

No, I think that's fairly clear. I would give a bonus on attempts to pinpoint, though. Maybe +4 to +10, but not too high. Keep in mind that this is already one of the top four cantrips in the game—it's pushing the "cantrip" label as-is.

Make a touch attack, roll miss chance, and hope for the best. At the least, it will make it hard for the hag to stealthily escape.


Casual Viking wrote:

Yeah, this isn't "ambient light from nowhere" light without a visible source. The light isn't coming from no source, rather it's coming from an invisible source. And by definition an invisible source can't be a visible source.

Given the situation, I think a better way to visualize it would be to say "Imagine a shirt that is glowing, now photoshop out the shirt but leave the light".


Imagine a lit candle, now photoshop out the wick.

Sovereign Court

I think Casual Viking's take is reasonable. It's a directional light without apparent source, but going in many directions, so if there's enough shadow you could look for what point all the light is coming from.

But if there's too much ambient light there's not enough shadow.

This could be the combat where the party is trying to shut off their light sources so they can "see" the invisible enemy :P


Yes, you can cast light on an object she is carrying, with normal 50% miss rate.

If you do so, I think it reasonable that you only get the creature's general area, not her exact square. You could easily land a fireball, but an arrow would be a lot harder. While it is possibly to triangulate her position from shadows, it's not something you can do quickly or in combat. At least that's my take on it. I would certainly give a bonus on perception to notice what square she's in.

If you succeed in landing the light spell on some object in the invisible Hag's possession, you don't necessarily know exactly what object you got. You might have got her hat or her shoe or her satchel.

That's not actually what it would look like at all. Whenever you see a candle, or a lightbulb, or led, or other 'point' source of light, you effectively are only seeing the light from it. If any of those objects were somehow made invisible, it would look nearly identical to what you see now. If you're outside in the dark, and someone shines a flashlight at you, you only see the light from the source, you don't see the flashlight at all. And yet, you can pinpoint the location exactly.

I think what most people are envisioning is that they wouldn't see the actual photons traveling directly from the source to your eye, which is what forms the image of the lit source in the first place, but rather only indirect light reflected from the environment.

I don't think that's how an invisible light source works. A point source of light is easily pinpointed, even if the 'source' is invisible.


Yes, 50% miss chance and otherwise works (sure, assuming she is not naked, as mentioned). Although I would raise my eyebrow a bit at the metagameyness of "She took a 5 foot step so must not have moved any further" ...

Sovereign Court

@Ozy: I wasn't disagreeing with that, exactly.

What I was getting at is that a Light spell creates directional light coming from an object. Specifically, with brightness equal to a torch.

On a sunny day outside, that's not necessarily enough. The ambient light from the environment might overwhelm it. On a sunny meadow, I don't think you could track an invisible torch by the light it sheds.

Indoors it would be doable maybe. I'd allow a Perception check each round to pinpoint it.

In an otherwise dark cavern, it would be an automatic success.

But you may want to have someone dismiss that Daylight spell.


1 person marked this as a favorite.

Depends on how close you were.

You absolutely can see a bright LED even outside in the sun, and what you are seeing is the directional light.

For that matter, you can see a fire during the day, and that fire you see is the generated light, so if you can see a fire you can see an invisible torch. The flames from the torch are not the physical source, they are the actual generated light that you're seeing.

Not if she made her save against the spell as her garments are definitely not "unattended oobjects".

Light does not have a saving throw or SR, nor does it specify anywhere it being restricted to unattended objects.

If you're going that way. Light can not be cast on a creature, nor any part of a creature... clothes are part of a creature for the purposes of this discussion.


Quote:

Uh what? Clothes are equipment, they're listed in equipment in multiple books. The only time they might possibly be part of a creature is while morphed in during wildshape or something.


There is no save or SR allowed vs light spell. It is not designed as a combat spell.

This is really pushing the limits of what a cantrip can or should do.

For spells that say attended items get saves, yes. For spells that do not specify attendance of objects either way and have no save, no.

Attendedness of objects is relevant to, for example, chill metal. It is totally irrelevant for light.

Quote:
To target worn gear you basically have to deal with the character's defenses.

Only to the extent of being able to touch it while it moves along with the witch, which is already all accounted for by needing to succeed in a melee touch attack and by the 50% miss chance for total concealment.

There are no other relevant "defenses" for this spell.

It doesn't allow you to make a touch attack to touch the item. It isn't a held charge.

Again, touching a worn item in regards to this spell, is touching the character. There are no special provisions to do what you say it is doing in combat.

Edit:

Magic; Aiming a spell wrote:

Some spells have a target or targets. You cast these spells on creatures or objects, as defined by the spell itself. You must be able to see or touch the target, and you must specifically choose that target. You do not have to select your target until you finish casting the spell.

You can't just stick your hand into a square and " fish" for a touch to get the spell off. So the whole argument about the situation is irrelevant, it can't happen.

Er, what are YOU talking about? The OP is about light on an invisible character.

Light isn't a held charge and as I pointed out above, you can't do it anyways.


Quote:

It doesn't allow you to make a touch attack to touch the item.

Touching a creature is a touch attack. This particular object is moving perfectly in sync with a creature. Touching the object is super obviously exactly equivalent in difficulty a touch attack to the thing that is moving it.

If you disagree, then what other better rules do you follow for touching attended objects?

Quote:

Yes you can, CRB: "A creature can grope about to find an invisible creature. A character can make a touch attack with his hands or a weapon into two adjacent 5-foot squares using a standard action."

Are you suggesting that it's somehow harder to grope about for an object than a moving creature?


Light has the same target language as shocking grasp, cure light wounds, and other touch spells. Why are you claiming that it works differently?


_Ozy_ wrote:

Because there is a HUGE difference between a held charge and a spell that requires a target at the point of casting.

So you cast the spell, which requires a target, as it is NOT a held charge as a standard action. Then somehow the spell doesn't fizzle due to not having a target (like the rules state it would) as you spend another standard action groping for something?

If it were a held charge then yeah, you could do it that way. But spells that aren't charges need to have a target when the cast is completed or they fizzle. Light doesn't mention ANYTHING about being a held charge, you don't just get to say "it is" and use it that way, sorry.

Does the spell say it is a held charge?

Because I'm not sure how it is in your wonderland, but in the real world, unless the spell states it is something you don't get to randomly assign properties because it sounds good to make it so.

A spell needs a target when it is cast unless otherwise stated. A held charge sticks around your hand which is what allows you to "fish" with it. There are two separate and distinct options here. You don't just get to lump them together because you want to use it a certain way.

If you are going to argue rules points, at least do yourself the favor of actually reading the subject matter.

Because unlike shocking grasp, the Light spell does not have language that gives you a free melee attack with the option to hold it for later. You either are ready to complete the casting all at once, or the spell is aborted.


Skylancer4 wrote:

Uh yeah it does require one. And it has one: the witch's clothing. That's an object. The target says "Object" I am satisfying the target requirements just fine.

Quote:

Okay? What does this have to do with anything? It's all happening in the one standard action. The spell Light already involves touching an object as part of it's 3 second standard casting. I have no need for additional actions later or held charges.

Quote:

It doesn't fizzle because it DOES have a valid target: the object that is the witch's clothing. Clothing is an object.


Guys, this is basic stuff in the general magic rules, you don't need specific charge language:

Quote:
Touch Spells in Combat: Many spells have a range of touch. To use these spells, you cast the spell and then touch the subject. In the same round that you cast the spell, you may also touch (or attempt to touch) as a free action. You may take your move before casting the spell, after touching the target, or between casting the spell and touching the target. You can automatically touch one friend or use the spell on yourself, but to touch an opponent, you must succeed on an attack roll.
Quote:
Holding the Charge: If you don't discharge the spell in the round when you cast the spell, you can hold the charge indefinitely.

Edit: Skylancer, guess you have some reading to do. ;)


hmmm ? why Light spell? change it.

if you dont like Light spell as example then use Arcane Mark for this debate

theoretically it shed light like candle

Magic Section.

Aiming a Spell.

You must make choices about whom a spell is to affect or where an effect is to originate, depending on a spell's type. The next entry in a spell description defines the spell's target (or targets), its effect, or its area, as appropriate.

Target or Targets

Some spells have a target or targets. You cast these spells on creatures or objects, as defined by the spell itself. You must be able to see or touch the target, and you must specifically choose that target. You do not have to select your target until you finish casting the spell.

Looks like it says something about being able to see the target and specifically choose the target, so the invisible -for me- garnments of the witch doesn't pass the targeting test.


This is pushing the limit for what a cantrip can do.

A 0th level spell does not counter a 2nd level spell. I don't care what the argument is.

There are already rules for targeting an invisible creature or object with a touch spell, you target the square and they get a 50% miss chance.

None of the rules you quoted prevent this from applying to the light spell touch attempt.

*facepalm*

It's not an auto-counter by any means, you need to pinpoint, and then, only if you're successful, waste an action fishing around for 50% touch chance. How did you pointpoint in the first place?

If you want to house rule otherwise, nobody is stopping you, but you should at least recognize what the rules actually say regarding touch spells, attacks, and holding the charge.

well not rly Sir , first you need know where is Invisible Hag

second you need touch her

third: she will got free AoO on you

IMHO yes you can try use cantrip but its not worth the cost


The word 'specifically' is quite clear. I can not specifically target something I can not perceive and distinguish from the rest of the universe.


Numarak wrote:

You specifically target the clothes of the creature that you touch. The target is specified by what you touch. If the creature happens to be naked, unbeknownst to you, the spell fails.

Similarly, if you have a shocking grasp charge and you're fishing around to deliver it to the invisible enemy spellcaster but you screw up the pinpointing and accidently touch your friendly invisible rogue, guess what. He gets zapped even if he wasn't your 'target' because the spell target is specifically what you touch.


If your interpretation of 'specifically' was correct, which is not, then you are telling me that you can cast a Magic Missile against an invisible target without being able to see invisible things.

P: I cast magic missile on that witch.
GM: But you can not see it!
P: But I'm able to touch it!
GM: Oh, yea, sorry, I forgot that...

Another one:

You have a spell that targets a chicken and turns it green. You want to turn the chicken named 'Toy' to green. There are 317 chickens in front of you, all of them you can see clearly, although only one is 'Toy'.

P: I cast the Greenatoshy spell to turn Toy green.
GM: But you can't specifically target it!
P: But I can see them! Or touch them!

We can debate what 'specifically' means, but your proposal, imho, leads to some bizarre interpretations.


Er, no I'm not. Magic Missile is not a melee touch attack. There are rules on how you deliver touch attacks to invisible targets.

Quote:
A creature can grope about to find an invisible creature. A character can make a touch attack with his hands or a weapon into two adjacent 5-foot squares using a standard action. If an invisible target is in the designated area, there is a 50% miss chance on the touch attack.
Quote:
If a character tries to attack an invisible creature whose location he has pinpointed, he attacks normally, but the invisible creature still benefits from full concealment (and thus a 50% miss chance). A particularly large and slow invisible creature might get a smaller miss chance.

And then for Magic Missile:

Quote:
The missile strikes unerringly, even if the target is in melee combat, so long as it has less than total cover or total concealment.

See the difference?

As far as your other spell, I'm not sure what you're getting at. If the spell has Range: touch, like the light spell, then you touch a chicken and it turns green. If you touch the wrong chicken, it still turns green, just like the shocking grasp example earlier.

Are you saying that once you declare your target, shocking grasp will only discharge if touch your specifically declared target?


You nearly convinced me, only two more questions, the quotations you put are for invisible creatures, can you find a quote that works for invisible objects? Since Light target only objects?

Can you turn Light into an offensive spell? Can you attack with it? I think you can't.

EDIT: and answering your last question, what I've tried to say is that for me does not make sense to grab something you can't see and 'specifically' target it. You said you 'specifically' target it by grabbing it, but the problem is that you must specify it before touching it, not after touching it, like: "oh! I touch some clothes! I target the witch's skirt!" that is your proposal, but actually, you finish casting the Light, then you specify the target, like "the witch's spectacles", and then you 'specifically' have to touch the spectacles. For me, this interpretation goes far beyond the scope of 'Light'.
