GM Abraham's Emerald Spire

Game Master Abraham Z.

Altovin steps backwards before fleeing to heal.

"I have to heal before this pain overwhelms me."

CLW: 1d8 + 1 + 1 + 2 ⇒ (4) + 1 + 1 + 2 = 8

If it hits the splash does not do any damage, but it does do AoE damage and a bomb is the ideal foil for a swarm. Also remember that they are on fire from the explosive bomb.

Yanda makes a dash for the closet, her safe place for the moment, wheels around, and lobs another bomb and the annoying swarm.

+9/3d6+8, 11 splash bomb [rng: 20 ft; 20/x2*; fire] (+3[BAB] +3[dex] +1[throw anything] +1[pblank] -1[deadly aim] +2[mutagen]/3d6 +5[int] +1[pblank] +2[deadly aim]) Forgot the mutagen last time!

Conditions:

Squares in the corridor down the stairs are difficult terrain (water at least 2' deep);

Courage - dmg;
Yanda - 13 dmg; mutagen (00:50); shield (00:05);

Yanda's first bomb badly burns the crab swarm.

Altovin takes a moment to heal himself.

Yanda hurls another bomb, and this one is sufficient to disperse the remaining crabs, who suddenly don't seem quite so hungry anymore.

And, just like that, a strange calm silence suddenly falls upon the battlefield. It has been less than two minutes since the group entered this area of the Spire - though it perhaps felt much longer - but now, finally, the conflict appears to be over. At least for now. There is no sign of the blue-skinned caster or his small companion.

Pathfinders are victorious! Out of combat!

What would you like to do?

First off Yanda heals herself.

clw: 2d8 + 2 ⇒ (3, 7) + 2 = 12 (good enough)

After she heals herself, she announces, "Well, let's get on after that wretched tormentor."

Which is a bit ironic, even if sensible.

Shabah fishes out their wand and offers it to whoever is willing to use it.

"Most sensible, Firewarden. Shall Sir Dasus and I continue to take the lead?"

CLWs: 2d8 + 2 ⇒ (4, 6) + 2 = 12

Yanda and Shabah both heal themselves.

CLW: 1d8 + 1 + 1 + 2 ⇒ (7) + 1 + 1 + 2 = 11

Altovin begins to squeeze out his damp cloak before healing his wounds with a wand.

"Is everyone else okay? Let's make sure we didn't miss anything before we head deeper in? I will be right behind you all."

We head out, Dasus in front, Altovin in the rear.

I moved our icons to show where we are going.

Conditions:

Fully healed, the group bravely resumes their exploration.

Dasus Reflex: 1d20 + 6 ⇒ (9) + 6 = 15

To his surprise, Dasus finds that beneath the murky water down the corridor there are further descending steps. He nearly trips over them, but manages to right himself and alert his comrades, who are then able to descend with no great difficulty.

However, as they feel their way down the stairs, the group soon realizes that the water here is even deeper, about 5'. Altovin will need to make swim checks while moving, the others can still walk, barely and with difficulty; Courage can fly above the water, though there is not very much space between the water and the ceiling.

Map updated. Note that on the map there are some dotted lines on the corridor you are currently in - these simply show that this corridor is passing beneath another one up above (which you of course have only seen the entrance to back in the water elemental room).

Unnless we come to a branch or room we keep traversing the corridor. No point in stopping here.

Yes, but I wanted to give you a heads up about the changing environmental conditions (i.e. deeper water) in case anyone has anything they want to do in relation to it. For reference, I'll hand wave any concerns about your gear getting wet (so no worries about your alchemical gear, scrolls, etc. unless the item specifically calls out an effect when it gets wet). However, besides Swim checks being required, the underwater combat rules will likely apply. Fyi.

OK. Not much I can do about it though. Except cry over her useless bombs.

"Oh...did I mention I also don't like water...well...I don't." Altovin says letting his fear get to him once again but he continues on as Courage bops him on his head as he goes.

Swim: 1d20 + 2 + 1 ⇒ (17) + 2 + 1 = 20 Can I take 10 on these outside of combat?

I'd expect so ::shrug::

Shabah waits patiently behind Dasus, only advising in a low voice, "We should decide on a pattern for our search. Perhaps we should begin by turning left at each intersection."

After all - 'Left is always Right'

Yes, you can take 10 on these Swim checks out of combat. DC 10 for calm water (which this is, at least currently).

As the group moves along the corridor, a second small flight of steps, hidden beneath the murky water, brings the group into even deeper water. Swim checks (taking 10 is fine for now) are now needed by everyone except Courage.

The hallway’s ceiling slopes downward along the southern stretch but opens up as it enters a room which is filled from wall to wall with water that reeks of dead sea life. A cascade pouring from the northern wall (from the room where Shabah killed the water elemental) churns up silt and other filth in the water, creating a murky mess. Effectively, the murky water grants concealment to anything in it, or total concealment to anything in it more than 5' away.

Map updated. Note that although you can see two doors on the map now, in-game you cannot (yet) see either of them due to them being under water.

Disgusting.

"Please allow me to scout forwards while our vision is occluded. If there are no threats, then we can continue."

Yanda has no trouble with the water as long as she takes it slow (Swim +0 gives a 10 on take 10).

"Be my guest. I won't be much help in this room. If someone is injured, I will try to heal them, but that is about the limit of my usefulness, unfortunately."

Shabah, go ahead and move yourself, showing the path of your scouting. Also, please remind me of any relevant details about your current form (besides swim speed, anything else I should know?).

Yanda, taking 10 for 10 is sufficient.

Just Darkvision and reach on their tentacles. Real Cecaelia can use their tentacles for blindsight, but alas, Monstrous Physique does not permit it.
Two moves' worth put into slides.

Shabah moves into the room to scout it out, and quickly discovers that the water here, as in the corridor, is about 8' deep. The water smells awful, as if something, or many somethings, died here long ago.

Note that Swim checks will be required at the start of every turn.

They don't get very far before discovering that the room is not unoccupied. This fluid creature’s roughly humanoid form is composed entirely of thick gobbets of soggy, brown mud.

The creature slams at Shabah with a muddy limb...
Slam vs flat-footed, underwater: 1d20 + 13 - 2 ⇒ (5) + 13 - 2 = 16
... but luckily misses.

Altovin, Dasus, and Shabah are up!
Don't forget Swim checks and that the Underwater Combat rules apply

Shabah's altered eyes widen in surprise and distaste at the surprising creature.

"Some sort of mud creature is attacking!"

Then, they set to punishing it for its transgression!

Bite (PA): 1d20 + 11 - 1 ⇒ (4) + 11 - 1 = 14

No swim check is required from Shabah since they have a swim speed, nor from Courage since it is flying above the water.

Shabah unleashes a barrage of attacks against the strange creature. Shabah, it doesn't look like you applied the underwater combat adjustments to your attacks, correct? My understanding (but I'm willing to be proven wrong if any of you disagree - it's always struck me as a rules oddity) is that these underwater combat adjustments apply even to creatures with swim speeds or the aquatic subtype; thus, I applied a -2 to my creature's attack, and if it had hit I would have halved the damage, because it was an underwater bludgeoning attack. Assuming that's all correct, all of your attacks - except the bite, which counts as piercing - will be at -2 & half damage, which I will now factor in as a resolve your attacks.

Shabah hits the creature with both of their claws and one of their tentacles. Unfortunately, none of these attacks appear to harm the creature at all! Shabah, besides the underwater effect, you are dealing with some sort of damage reduction. Let me know if there are any properties that would apply to your natural attacks (aside from them being piercing/slashing/bludgeoning).

Altovin and Dasus are up!

Swim: 1d20 + 2 + 1 ⇒ (15) + 2 + 1 = 18

Altovin works to keep up with the group swimming along the best he can with Courages help.

As he treads water he summons a blessing from Jaidz to assist the group.

Cast Bless.

Altovin treads water and blesses the group for what is sure to be a difficult battle.

Shabah, we forgot to roll 20% miss chances for each of your attacks; it doesn't matter because they did no damage anyway, but just fyi. Also, Brown did not roll the same on its attack because reasons, also fyi.

Dasus is up!

It's definitely fuzzy, but here's James Jacobs talking about aquatic natural attacks not being affected.
The relevant rules text to hang that ruling on is that the penalties are described as applying to "The rules presented in the Pathfinder RPG Core Rulebook for underwater combat apply to creatures not native to this dangerous environment [i.e. underwater]" and "Land-based creatures can have considerable difficulty when fighting in water."

Ah, thanks for posting this - the rule always seemed dumb to me but I'd had several GMs rule it the other way on me. We'll go with James Jacobs' ruling. I'll go back and see how this may have affected your (and its!) attacks.

Retcon the status block due to rules update regarding natural attacks for aquatic creatures not being subject to the underwater combat penalties.

The creature's attack against Shabah's flat-footed AC is now an 18, which looks like it still misses, but just by 1. Shabah, confirming that your flat-footed AC is 19?

Three of Shabah's attacks hit the creature (Claw, Claw, Tentacle) - the retcon does not change that.
Claw 20% miss chance, high is good for Shabah: 1d100 ⇒ 84
Claw 20% miss chance, high is good for Shabah: 1d100 ⇒ 26
Tentacle 20% miss chance, high is good for Shabah: 1d100 ⇒ 23
None of the attacks go astray due to the murkiness of the water.

After retconning the damage - i.e. not halving the damage for non-piercing attacks... Although it hits, the tentacle doesn't seem to harm the creature at all. Both of the claw attacks do some modest damage. (Status block updated above - the creature took a total of 9 damage from Shabah's attacks)

Botting Dasus' swim check - it doesn't appear that he has any ranks in Swim, so I *think* the check is:
Dasus Swim check, Armor Check Penalty: 1d20 + 3 - 7 ⇒ (2) + 3 - 7 = -2
The heavily armored half-orc attempts to swim forward to join the battle, but instead finds himself sinking beneath the water, compelling him to hold his breath! (I've represented this on the map by adding a thick border around Dasus' icon)

The creature slams into Shabah...
Slam: 1d20 + 13 ⇒ (13) + 13 = 26
dmg: 2d6 + 3 ⇒ (4, 6) + 3 = 13 reduced to 11 due to DR
grab: 1d20 + 16 ⇒ (10) + 16 = 26
... grabbing them and pulling them underwater! Shabah, I presume your current form doesn't give you the ability to breath water? I've added a thick border around your icon to represent that you are under water and holding your breath.

And it slams again...
Slam: 1d20 + 13 ⇒ (10) + 13 = 23
dmg: 2d6 + 3 ⇒ (2, 2) + 3 = 7 reduced to 5 due to DR

For clarity's sake, I'll increment the counter of rounds of breath held on the PC's turn (so even though Shabah has now been pulled under water, their counter is at 0 rounds until their turn).

Pathfinders are up! The bold may act. It is now round 2 (except for Yanda, who is at the end of round 1). I've added the link for the drowning rules at the top. Good luck!

"Should we, ah, move to shallower water? Provided our many-limbed friend can escape, of course?"

swim: 1d20 + 0 ⇒ (14) + 0 = 14

In spite of all her talk about moving away, she instead swims towards Shabah and get ready to tap him with her wand of CLW. Unfortunately a full move only gets her 15' even with a successful swim roll.

Flat-Footed is indeed 19 - 7 armor, 2 natural armor (monstrous physique and mutagen both provide a non-stacking +2 Natural Armor, alas)
On the plus side though"If the form grants a swim or burrow speed, you maintain the ability to breathe if you are swimming or burrowing.

Shabah replies in a stream of bubbles to Yanda's query, but seems for the moment determined to escape by simply carving their way free!

Yanda manages to keep her head above water and swims forward in the nasty water to try to support Shabah.

Shabah thankfully has no difficulty breathing underwater, and unleashes a barrage of attacks against the foe that has grappled them. Unfortunately, only a single claw manages to pierce its armor, and even that claw does less damage than expected.

23 damage, reduced to 19 by Shabah's DR. Grappled. By my tally that takes Shabah to 35 dmg, barely conscious. Correct?

Start of Round 3

Fortunately, Altovin's lifelink restores some health to Shabah. 5 dmg to Altovin; 5 healing to Shabah (total dmg is now 29).

Pathfinders are up! The bold may act! Good luck and don't forget your Swim checks.

swim: 1d20 ⇒ 20

Planting a foot on someones appendage, Yanda manages to stay afloat. Though with all the appendages flailing about under the murky water Yanda isn't quite sure what it was she pushed off on, only that for a few more vital seconds she is able to keep her head above water. Taking advantage of the reath of air she mutters the command word and touches a briefly appearing, and somewhat desperate looking, tentacle belonging to Shabah. Or so it seems to Yanda, the way it wiggled frantically.

cure light wounds: 1d8 + 1 ⇒ (5) + 1 = 6

Good (if unfortunate) tally, yeah

Shabah's face becomes a rictus of pain and concentration as they try to carve their way free from the goop that binds them with all the extra strength Yanda's providing them.

Shabah, before I resolve your attacks, a) are you subtracting 2 from your attacks for being grappled (and if so, no need to do that, since it's a wash with the grappler's AC reduction)? and b) are you adding +1 from Bless? and c) your natural attacks are not magical, correct?

Altovin continues to bob along in the water while keeping the group healthy. He doggy paddles by Dasus and gets ready to heal Shabah.

Shabah, ok, then just to clarify, what's the -1 listed in your attacks from?

Shabah attacks the mud creature multiple times, managing to hit it with their bite, a claw, and a tentacle. Unfortunately, the tentacle doesn't seem to harm the creature at all, while the other two attacks do less damage than expected.

Altovin bravely swims towards the battle, managing to keep himself afloat.

Botting Dasus
Dasus swim check, armor check penalty: 1d20 + 3 - 7 ⇒ (20) + 3 - 7 = 16
Dasus finally manages to struggle to the surface and draw a swift breath of air before bravely swimming forward in his heavy armor to try to engage their foe. full-round action to move half-speed, which is 2 squares due to heavy armor.

The muddy monstrosity first releases his prey and then attempts to bash Shabah again...

Yanda, you have to fail by 5 to sink underwater; luckily you only failed (the DC 10 check) by 4, which means you aren't able to move, but you don't go underwater.

Yanda reaches out and taps Shabah with her wand of healing. I'll rule that no concealment check is required since you can definitely see Shabah and they are not trying to avoid being hit by the wand. A separate question - which is moot for now because you didn't actually go underwater - is whether a concentration check would have been required for the wand command word while underwater. Hopefully we won't need to figure that one out! :-)

Altovin also stays afloat and gives even more healing to Shabah.

Shabah and Dasus are up!

My -1 to hit is from Power Attack

The focused grimace on Shabah's face gradually shifts to one more triumphant, as the tide begins to turn with their allies' support!

Bite (PA): 1d20 + 11 - 1 ⇒ (18) + 11 - 1 = 28
P/B/S: 2d6 + 8 + 2 ⇒ (5, 3) + 8 + 2 = 18
Claws (PA): 1d20 + 11 - 1 ⇒ (15) + 11 - 1 = 25
B/S: 1d6 + 8 + 2 ⇒ (4) + 8 + 2 = 14
Claws (PA): 1d20 + 11 - 1 ⇒ (8) + 11 - 1 = 18
B/S: 1d6 + 8 + 2 ⇒ (5) + 8 + 2 = 15
Tentacles (PA): 1d20 + 6 - 1 ⇒ (17) + 6 - 1 = 22
Bludgeoning: 1d6 + 4 + 1 ⇒ (1) + 4 + 1 = 6
Tentacles (PA): 1d20 + 6 - 1 ⇒ (6) + 6 - 1 = 11
Bludgeoning: 1d6 + 4 + 1 ⇒ (2) + 4 + 1 = 7

I'm mostly back, I think!

Swim: 1d20 + 3 - 6 ⇒ (1) + 3 - 6 = -2

Finally close enough to the fight, Dasus starts to try to attack, but ends up sinking back under the water. Even as he sinks, holding his breath once more, he tries to swing his axe through the water.

Attack underwater: 1d20 + 7 - 2 ⇒ (16) + 7 - 2 = 21

Miss chance: 1d100 ⇒ 47

Damage: 1d8 + 3 ⇒ (5) + 3 = 8

so, half damage is 4

Did I get that right?

Shabah lashes out at the muddy creature with a dizzying array of attacks.

Meanwhile, Dasus once again finds his heavy armor dragging him beneath the water, and once again he must hold his breath simply to avoid drowning. Welcome back, Dasus! Glad to hear that you are back with us. Unfortunately, I don't think you can attack the creature this round because you are two squares away from it. Since you failed your swim check you can't move, so you have no way of getting adjacent. But yes, I think that would have been correct for your attack if you had been able to make it.

The muddy creature changes its tactics and attempts to move directly over Shabah! Shabah, you can choose to either take an AoO against the creature or make a reflex save to avoid it. I'll resolve the rest of its turn after you do so.

Response needed from Shabah.

If this is an engulf and not just an overrun, I'll be real mad at myself for not dodging...

Reflex: 1d20 + 9 ⇒ (6) + 9 = 15 Might be upset anyways :-p

Sorry for the posting delay everyone - things are likely to be a little hectic for me until Thursday or Friday but I'll post when I can.

The muddy creature moves over Shabah and engulfs them! Shabah, you gain the pinned condition; fortunately since you can breathe underwater it does not begin to smother you.
dmg: 1d6 + 3 ⇒ (3) + 3 = 6 reduced to 4 by DR

Start of Round 5

Once again, Altovin's life link heals Shabah, telling Altovin that Shabah is still alive, even though they have disappeared from view, under the dirty water, and engulfed by the mud-like creature that is now in the group's midst!

Pathfinders are up! The bold may act!
Don't forget swim checks at the start of your turn; remember that the swim check just affects whether or not you can move, and whether or not you go underwater; whether you are underwater or not, and whether you pass your swim check or not, you can now attack brown since it is adjacent to all of you (except Shabah, who cannot attack due to being pinned), but remember the underwater fighting adjustments and also the 20% miss chance for concealment due to the dirty water. And of course by now you've all seen that it has some kind of DR.

Would you allow Yanda to deliver a bomb as a touch attack, provided it damages her as well as the creature? Also, if anyone tries to unpin Shabah, Yanda will do an aid as an action to help. Otherwise, Yanda is just going to heal Altovan.

swim: 1d20 ⇒ 4

Swim: 1d20 + 2 + 1 ⇒ (1) + 2 + 1 = 4

Altovin starts to struggle and dips below the water much like his linked ally.

Escape!! (Bless): 1d20 + 11 + 1 ⇒ (5) + 11 + 1 = 17

Shabah strains to tear their way free from within the muddy depths of the creature!

Sorry! Still having a few throat issues, apparently. And yeah, oops, I guess I mixed up icons when I posted last.

Swim: 1d20 + 3 - 6 ⇒ (8) + 3 - 6 = 5

Struggling against the weight of his armour, Dasus tries to get to the surface, but fails. Continuing to hold his breath, he puts all his strength behind swinging the axe.

Attack with power attack: 1d20 + 5 - 2 ⇒ (15) + 5 - 2 = 18

Miss chance: 1d100 ⇒ 10

Blinded by the muddy water, he can't even come close.
