World of Greyhawk: Company of the Grey Chain

She swears as Khessa shakes off the effect, and instead swaps places with the Mezzoloth, coming face to face with Khessa: "I'd rather fight you I think."

One Mezzoloth attacks Avery, while the other attacks Khessa:

Claw against Avery Attack: 27 Damage: 17 Slashing and they are Grappled and Restrained

Claw against Avery Attack: 16 Damage: 7 Slashing and they are Grappled and Restrained

Claw against Khessa Attack: 19 Damage: 10 Slashing and they are Grappled and Restrained

Claw against Khessa Attack: 9 Damage: 10 Slashing and they are Grappled and Restrained

The Deva attacks Mezzoloth 3

Holy Mace 1 against Mezzoloth 3 Attack: 17 Damage: 5 Bludgeoning and 22 Radiant

Holy Mace 1 against Mezzoloth 3 Attack: 12 Damage: 9 Bludgeoning and 17 Radiant

Both those attacks miss the Mezzoloth, and you all are up. Are Khessa and Avery Grappled and Restrained? And I think everyone but Xanrym will need to make con saves against the widening Cloudkills 16 Damage

(OOC: Avery should still have Protection from Evil and Good right?)

Quote from Ben_Evolent >>

Xanrym - DC 10 CON saving throw to maintain concentration on Bane: 21

(OOC: @drumdigby - A few comments:

• Don't forget that both Mezzoloths are still under the effect of Bane.  Therefore, Mezzoloth 3 will miss Khessa since 19 - 1d4 <  Khessa's AC 19. 
• Since Avery wears Adamantine Splint, critical hits count as normal hits.  Therefore, even though that first attack hits, it should just do normal damage, not critical damage.
• Of course, that Mezzoloth probably didn't land a critical hit since it should have been attacking with disadvantage because Avery is still protected by Theldrin's Protection from Evil and Good. 
• You said, "against the widening Cloudkill."  If that's just the regular Cloudkill, I don't think that the AoE grows (RAW).  The spell description just says, "the Sphere moves 10 feet away from you at the start of each of your turns."   That is, the AoE is still just a 20-ft radius sphere, but the that sphere moves 10-ft away from the caster, presumably moving west into S35 in this case. 
• If Mezzoloth 1 was the one that cast the Cloudkill, it needs to make a CON saving throw for concentration.

[[ OOC: Actually, I don't find this feature in Cloudkill's description that the area of ​​effect expands either... the only thing that's mentioned is that the area of ​​effect moves, but not that it gets larger.
And to the points raised by Ben, I'd add the fact that Orinielle grants Attack of Opportunity to Balthial  when she switches places with the Mezzoloth, unless she has a way to take the Disengage action.
In my post, I assume Khessa was missed because of Bane (she also still has a duplicate - but if she is not hit it does not matter) and out of the Cloudkill—which didn't expand. If I'm wrong, I'll correct my post. ]]

Round 3

Khessa smiles confidently at Orinielle: "Be my guest, Ms. Elite Statue. You'll find that my body is as steadfast as my mind."

However, feeling in a vulnerable position, the blonde arcane warrior mutters a quick incantation as she momentarily removes one hand from the hilt and traces an arabesque in the air with the rod, which focuses her magical energy: she casts Protection from Evil and Good.

Forgot that bane also affected attack rolls. Fair enough with the splint and protection from good and evil, here’s the attack with disadvantage: 24 . Probably have misread the Cloudkill spell, it moves 10ft east rather than expanding. Mezz 3 cast Cloudkill. 

Avery will attempt to break the grapple: 27

Save for cloud kill: 26

(OOC: Got it!  FYI - I went ahead and shrank the Cloudkill AoE on the map back to a 20-ft radius.  I also put a dark orange dot at its central point-of-origin so that it's easier to track when much of the AoE is clipped by the walls.  Tip: to move that origin point and the AoE at the same time, click the origin dot and drag it.  The AoE is "attached" and will move with it.)

Coriana manages to sneak a clear breath in before firing two blasts at the cambion outside of the cloud.
[[EB: AC 13, 2 force. AC 19. 4 force.]]
She then moves towards most of the rest of the party in the clear air.

Quote from drumdigby >>

Xanrym enters the next room, which looks to be a closet. Inside are a number of outfits that look to fit Fadheela as well as a large stone chest and a staff propped up against it. When he searches the north end of the room, he finds another secret door.

Round 7: Xanrym

Xanrym turns to call over his shoulder to Theldrin and Syllen, "It's a sort of closet with Maroe's robes, a wizard's staff, and a chest.  But there's also a hidden door at the back."  Looking back, Xanrym sees the yellow-green fog -- thick as ever -- just as Coriana emerges from it.  He hopes that Khessa and Avery are still alive and fighting the Mezzoloths with the support of the berserkers, but he doesn't know how he can help them with that poisonous cloud blocking their way. 

Either not realizing that the poisonous cloud is moving (and about to open a clear path to get into S32) or seeing that the cloud is moving (and worried that the poisonous cloud will soon cover the north end of the room too!), Xanrym announces, "I'm going to see where the secret door leads!"  He tries to open the secret door, hoping that it gives them a way to escape the poisonous cloud and somehow rejoin the fight against Orinielle.  (The other secret doors in the Necromancer's Spike were easy to push open once Theldrin found them.)

Xanrym's action will depend on whether he can open the secret door and what he finds when he does:

• If there's a monster behind the door, he'll probably attack with a spell.
• If there's a long tunnel that continues beyond the edge of the light or that turns east or west, he moves forward and may simply dash, hoping to find that it leads them back to S32 somehow.
• If there's another room or a shorter tunnel, he'll move forward more carefully and Search the space for threats or other secret or hidden doors.

Movement: Up to 30-ft of movement, through the secret door, before deciding his action.
Action: Cast a spell (if he encounters another monster) / Dash if it's a long tunnel, or Search the next area (Perception: 17)
Free Action: Talking, Opening the secret door

Concentration: Bane, round 3 of 10

Bardic Inspiration:
  Avery (since post #6360)

Once within the next 1 hour, when the you fail a D20 Test, you can use the bardic inspiration to roll 1d8 and add the number rolled to the d20, possibly turning failure into a success.
If you use the bardic inspiration, but the D20 Test still fails, you keep the inspiration die because of Xanrym's Unfailing Inspiration.

Quote from Aaggie >>

Avery will attempt to break the grapple: 12

Save for cloud kill: 24

(OOC: @Aaggie - it looks like the Cloudkill had already moved past Avery this round, so he doesn't need to save and won't take damage.  Also, remember that Avery has a 1d8 Bardic Inspiration die from Xanrym in case you want to roll it to boost that attempt to break the grapple.  Because of Xanrym's Unfailing Inspiration, there's no downside if the roll still fails to break the grapple.)

Syllen, annoyed that he can not get close enough to heal the main fighters or get line of sight teleports next to the Deva. Syllen gives a quick prayer to the Cosmos that he will not get attacked by the Deva.

“I only appear next to you in order to help my friends.”

BA: Misty Step next to Deva.

Action:Guiding Bolt at Mezzoloth 3 to Hit: 24 Damage: 6 Radiant

Movement: Crows move so that they can Hit the Mezzoloths and Cambion. DC 15 Dex Save or take 20 Slashing Damage.

(OOC: @JehanO - Can Syllen Misty Step next to the Deva?  I thought that the destination had to be an unoccupied space you can see.)

(OOC: I assumed that because the doorway is not blocked and the ceiling being 10 feet tall Syllen could get line of sight to the ceiling by the Deva. If I am wrong than I guess Syllen couldn't Misty Step. Now I am wondering if the Ceiling above the Berserker in the doorway is considered unoccupied. I forgot to mention Syllen is on the ceiling. Sadly was trying to write out my turn at work really fast.

@drumdigby let me know if I was mistaken that Syllen could Misty Step.)

(OOC: @JehanO - Ah!  I forgot about Syllen's new Spider Climb ability!  Yeah, depending on how high off the floor the spell's origin point is, there should be a gap of ~0.7 to 3.0 feet between the east wall and the AoE at the top of the doorway.  I can just picture Syllen crawling like Spider-Man along the east wall, over the heads of the berserkers, to peer back through the short hallway and into S32.)

"I think the cloud may be dissipating a bit..." Theldrin calls out to Xanrym.  But he's interested in a possible way around to the other side of the battle so adds as he moves into the closet, "What do you see, my friend?"

OK here's the attack against the Cambion from the Deva: Attack: 14 Damage: 9 Bludgeoning and  15 Radiant

Cambion DEX Save: 11

Mezzoloth 1 DEX Save: 18

Mezzoloth 2 DEX Save: 6

Minus Bane for Mezz 1: 2
