The Dread Warrior (DW1) bursts into flames and is consumed by them.

The second Dread Warrior moves out of the Sickening Radiance sphere and drawing his Battteaxe and attacks Velmine twice with his two handed Battleaxe Attack: 8 Damage: 3 and again Attack: 12 Damage: 11. But it looks like he was distracted because he missed her both times. 

 The Wizard casts Fireball centered on G12. Everyone make Dex save DC 14 or take 32 or half as much on a successful save. 

Gelatinous Cube Dex save 0

Dread Warrior Dex save 3 

I will give Xavier a chance to cast counterspell if he wants before doing the Gelatinous Cube's turn. 

Xavier casts counterspell negating the fireball 

(auto succeeds on spells 3rd level and below)

The Wizard's Fireball spell briefly sparks and then dies as Xavier's counterspell works.

TW3 takes 17 Acid damage and is digested by the Gelatinous Cube (Oops I forgot he escaped and then got killed. I can't delete the roll without getting the flag).

The Gelatinous Cube feels a body impact the ground beside/behind it and moves towards (1= stay on the Wizard, 2= attacks Xavier) 1 the Wizard and tries to Engulf him.

Wizard's Dex save 11

The Wizard is able to avoid being engulfed. 

Back to the party 

Eiren calls a spectral hand to choke the wizard...

Chill Touch Attack: 12 Damage: 5 necrotic 

Cons save 27

Xavier casts burning hands toward the wizard and cube dc16 dex save or take 12 fire damage.  (I think I can hit both , if not move to d13 first cast and then move back to my current position)

spend sorcery point for empowered spell to reroll dice 15

Baik focuses his Sacred Flames on the Cube this time, hoping it isn’t as agile.

DC 16 dex save or 4 damage

(I know the game's in a pause for the time being, but hoping to bump this up, and add my turn which I missed before the break, I'm making this post.)

Velmine moves to H14, so she could face the Dread Warrior one-on-one, and with a shortsword and a dagger on hand, she uses the first one to stab at the foe right in front of her, and with the latter, she aims at the wizard and throws it.

Shortsword Attack: 24 Damage: 25

Dagger Thrown Attack: 10 Damage: 7 (With disadvantage because the wizard isn't within the close range of the dagger (20 ft.).)

Eiren's Chill Touch grabs the Wizard by the throat and chokes him to dead. The Wizard gasps and falls down dead.

Gelatinous Cube Dex save 1. 13.  A thin sheet of fire bursts from Xavier's hands and burns the Gelatinous Cube. 

Gelatinous Cube Dex save 2. 3. Baik's Sacred Flame rolls right after Xavier's burning hands, leaving the Gelatinous Cube badly burned, but still alive. 

Velmine moves to attack the Dread Warrior with her Shortsword doing considerable damage, but he is still standing. (As the Wizard is dead do you still want to throw the dagger at the Gelatinous Cube? )

Corvin is up 

(Actually, change that attack to be a melee attack against the Dread Warrior.)

Quote from Pertuie >>

(Actually, change that attack to be a melee attack against the Dread Warrior.)

 Does that change any of the rolls? Still with disadvantage? 

(Right, this time without disadvantage. But that's pretty much the only change I can see.)

 Corvin follows Baik's sacred flame with one of his own at the cube.

DC17 dex save or 16 damage

Velmine's dagger thrust does a little bit more damage to the Dread Warrior 

Gelatinous Cube Dex save 2. The triple battery of fire is too much for the Gelatinous Cube and it melts into a Gelatinous goop.

Velmine: H14 is in the Sickening radiance, roll a Con save DC 16 or take 21 radiant damage and a level of exhaustion before your attack. 

The Dread Warrior attacks Velmine twice with his Battleaxe His First swing Attack: 21 Damage: 8 hits her, while the second blow Attack: 21 Damage: 11 also manages to break through her armor if barely. Velmine took a total of 8 Damage after she reducess it.

Back to the party. Velmine and Xavier make your Con saves before acting 

Constitution Saving Throw: 21

Velmine uses Uncanny Dodge against the Dread Warrior's first attack. (Which lowers the total damage to 8)

For her turn, she stabs the Dread Warrior and then steps back to where she was before (I13), whether she kills him or not, so she could at least get away from the Sickening Radiance.

Attack: 16 Damage: 20

Velmine's sword glances off the Dread Warrior's armor doing no damage 

Corvin steps forward to smash at the dread warrior with his hammer.

Move to J13

Attack: 27 Damage: 20

Dread Warrior Con save 14

Corvin's warhammer finishes off the Dread Warrior. 

You are out of initiative

Cropped version of the 3 rooms. The one in the middle has the acidic vapors and a hallway heading north 

The last encounter only took 3 rounds, so if you don't recover any thrown daggers and/or check out the bodies, and if you dash through the vapors, Eiren should have 5 or 6 rounds of Bladesong left when you enter the northern room or hallway. 

Up to the party
