CON SAVE: 3 

"Ew! Rude!" Says Psalm as the poison nearly envelops him, but he manages to uncannily dodge it just in the nick of time, minimizing the damage.

He moves another 10' northwest, going flush against the wall to hide as he peeks down the northern hallway.

Turn Breakdown:

Finn's might strikes are able to fell the minotaur. It falls quiet on the floor where it lays.

To the North, Psalm sees a dimly-lit hallway with a downwards incline going East.

Zylborin will move 30' north and also take the dash action to move another 30' north, which I believe should get him to the column in the middle. 

//Not much else I can do at the moment, so I'll end my turn

Psalm holds his place at that corner and readies his dagger to trhow at any adversary who comes charging in from either hallway and steps within range. (20')

[[
For Zylborin, others creatures' space counts as difficult terrain. So would be 1 short. (Can do a zip around Finn on the diagonals after Dain/Sampson.) But looks right.
]]

As Psalm takes his hiding spot, Kobold 3 rushes towards the hall to join his companions. (would provoke Psalm's readied attack with advantage from hide)
He readies a sling to strike back.

Attack: 18 Damage: 5

[[ If Psalm hits the kobold, can ignore that attack if it would've hit. ]]

Following the first kobold comes a lizardman, dodging as it sees the attack on its comrade. Behind him another two kobolds and a goblin lying in wait.

[[ revealed a little more of the map as would've been seen while moving upwards ]]

note: UK6 was one of the extra rolls I had. So now all the party-members share initiative together.

Psalm's blade flies at the kobold as it turns the corner and steps into view.

Almost in the same gesture, he draws his rapier and charges into the western hallway, blade first, stabbing at the lizard man and calling out, "Tag, you're it!" before reversing course and racing back in the direction of his companions, high stepping with a Curley Howard style "woob-woob-woob-woob-woob" as he runs.

The moment he sees his comrades he crooks a thumb back behind his head and says, "Heads up, gents. Fresh batch of uglies comin' this way. Go on and give em' some love."

Reaction:

 Turn Breakdown:

Sampson gives an excited nod to Dain and Finn. He then dashes 60 ft up to the hallway Psalm was helping about! 

The rest of the combat was just out of Finn's sight... but he recognized Psalm's voice calling the enemy out. Quickly flying towards the announcement, he suddenly spotted the tiefling running back past him... with a curiously pleased look on his face.

Chuckling at the sight, the warlock pirate continued towards the side of the northern entrance, before turning to give himself a full view of the narrow corridor that his companion seemed to have been running from. Noticing there was still no tug from his spell, he focused his concentration on the lizardman in the front of the pack and braced himself for an attack.

MOVE: Northwest 15', then North 15'
ACTION: Dash North 25', then East 5' to press against the wall while turning to look down the corridor
BONUS: Re-target Hex onto the lizardman, giving disadvantage on his Strength checks

Finn has 6 rounds of Blink left, and only rolled a 6 on it at the end of his turn, so he again stays on the material plane.

End of turn!

Zylborin will move 15' to the left. If the Kobold3 is still alive, Zylborin will cast Vicious Mockery at the Kobold for 4 damage. Otherwise he will hold his action to cast Vicious Mockery at the next enemy that comes through the corridor.

"Late to the party? Not that we'd send YOU an invitation."

Dain moves 45 feet towards the combat, taking the Dodge action. He yells taunts at the newcomers in the hopes that they’ll fall for it and target him. 

“Too late to the party lads! Better play catch up while you can. Come and get some o’ this!”

Psalm takes down the advancing kobold (K3) with a swift dagger. As he enters the hall to attack the lizardman, the goblin and kobolds loose their missiles. (Readied actions.)

Goblin @ Psalm
Attack: 5 Damage: 6

K4 @ Psalm
Attack: 21 Damage: 4

K5 @ Psalm
Attack: 11 Damage: 3

Possibly distracted from the loosed missile, he's unable to find purchase with the rapier but his fancy footwork keeps him from being attacked as he dashes back to saftey.

Sampson, Finn, Zylborin, and Dain rush towards the battle. Finn hexes the lizardman. But as they make their rush, the chained half-dragon to the left of the entry looses a poisonous breath.

Target: 1-Finn, 2-Sampson, 3-Zylborin, 4-Dain
Target: 2
Damage: 20 poison with CON Save DC 11 for half

[[ Finn and Zylborin's movement both explicitly crossed into the 15ft cone range, so rolled target die as a way to also even the odds on non-explicit routes too ]]

The hexedlizardman makes his charge towards Finn, coming in range of Zylborin's readied vicious mockery.

Lizardman WIS Save: 3

Taking psychic damage from the bard's mockery, the lizardman is disoriented as it raises its club

Club @ Finn
Attack: 12 Damage: 3

and then tries to bash Finn with his shield.

Shield @ Finn
Attack: 13 Damage: 7

The kobolds are quick to follow up the lizardman's assault, taking advantage of the presence of their ally to heighten their aim with their slings.

K4 @ Finn
Attack: 23 Damage: 6

K5 @ Finn
Attack: 19 Damage: Unable to parse dice roll.

The goblin looses an arrow from its shortbow and then takes a moment to hide behind the walls.

Attack: 18 Damage: 7

Stealth: 7

Initiative

Lizardman (hex 6-damage, Goblin, K4, K5

The moment he sees his companions rush into the breech, Psalm pirouettes and runs back in the opposite direction...

...squeezing between Zylborin and the corner with a quick, "'Scuse me..."

...giving Dain a quick pat on the back...

...jogging past Sampson on his right while calling out, "On your left"...

...ducking between him and Finn to jab the Lizardman while calling out, "Boink!"

...Then ducking out of the way to take cover around the corner again....

TURN BREAKDOWN

(( Finn's CON Saves to keep concentrating on his spell (both DC 10) - 4 and 17 ))

Finn grunted as he was bashed, then pelted with a... rock, most likely? Whatever it was, it drew blood, irritating the pirate.

"Wait your turn!" he yelled with a malevolent grin, before turning back to spin into two quick rotating slashes towards the lizardman in front of him. The warlock then stopped in mid-air to admire his handiwork for a second before winking at the kobold that had struck him. "See you soon!" he laughed as he again vanished.

ACTION: Attack the lizardman twice, rolls from character sheet
* Oversized Blade Slash #1 - Attack: 12, Damage: 10 Magical Slashing + 6 Necrotic
* Oversized Blade Slash #2 - Attack: 19, Damage: 14 Magical Slashing + 1 Necrotic
BONUS: If the lizardman falls, will refocus Hex onto Kobold #4

No movement. Rolled a 16 for Blink, so he vanishes. Five rounds left on the spell.

End of turn!

"No takers eh? That's alrigh' I'll come to you."

Dain gives Psalm a thumbs up as he runs by, then continues his march toward the lizardman, stopping directly below it and bringing his axe down twice in quick succession.

Attack 1: 18 for 15 Slashing Damage 

Attack 2: 26 for 15 Slashing Damage

// @DM just confirming whether Zylborin was caught in the poison breath? I'll roll a Con save either way: 19

Zylborin would like to assess who is looking hurt if possible, if that's an action he'll cast a 2nd Level Healing Word for 12 hit points.

If it's not an action he'll shoot the Lizardman with his crossbow: To Hit: 14 Piercing Damage: 5

Then move up 15'

The might of Psalm and Finn's attacks fell the lizardman with ease. As Dain comes charging up he's able to get in the hall and down the two kobolds. 

[[ With the lizardman dead, assumed he'd move down the hall. Let me know if you'd rather he not. ]]

Zylborin is able to get closer to the combat, though with the lizardman dead he has no target.

[[ Zylborin was not the target of the poison breath. For healing word I have no issue with Zylborin being able to tell who's hurt without any check. So you're free to use your action as you see fit. ]]

2nd Level Healing Word for 8 hit points.

 

 Zylborin will heal Psalm for the above. He'll stay where he is and that'll be my turn.

(I’m good with that call. Rushing the next closest enemy is what I’d have done there)
