Corvin follows the others into the cavern (I think I can reach N10?), ignoring the lights that so entranced two of his teammates.   He fires off a Sacred Flame at the new Wight he can now see and moves his spiritual weapon 20 feet towards it (to O10)

Wisdom save: 20

DC17 dex or 5 radiant damage.

Baik enters the cavern and stops in K9 transfixed by the magical lights. At the end of his turn he take 13 necrotic damage 

Baik make a 2nd Wisdom save DC 13

Xavier is still entranced by the lights.

Corvin is able to withstand the lure of the light and moves into the cavern. Once he can see the new enemies (1 new Wight, 3 new Zombie, and 1 new Dread Warrior. All look like Xavier) the launches a Sacred Flame at the 2nd Wight. The Wight doesn't try to avoid the flames and is engulfed by them. 

 W1 Wisdom save 9

The Wight doesn't react at all the Corvin's Sacred Flame hitting him.

(It looks like I skipped Eiren last round)

Velmine and Eiren are up 

13

Baik stares at the lights. Oh, those are kind of pretty. Is that you?

Baik is shocked out of his trance.

Velmine slinks past Baik, snapping a finger in front of him. "Hey, wake up! We kinda need you in this fight too." She says, chuckling and then continuing her dashing footwork along until she passes south of Corvin, finally reaching P11, where she stops and pulls out her rapier. "Let's see how well this goes." She plunges against DW1.

Attack: 18 Damage: 21 Piercing

Before finishing, though, she steps away and dashes, cunningly, going back a bit behind Corvin until she's on  M11.

(She gets sneak attack due to Rakish Audacity, and no Attack of Opportunity against her due to Fancy Footwork.)

"We need a better plan!" says Eiren. "Whatever this mesmerizing effect is, it looks like it eats away at your flesh." He nods at Baik. 

Eiren moves to where Velmine was and sends a chill touch at the dread warrior, pointing and uttering a curse.

Attack: 26 Damage: 9 necrotic

 That will take you into the effect. If you still want to move to L8 and try that make a DC 13 Wisdom save. If you wanted to avoid the trap (?) make a different action, however you will not be able to see any of the enemies until you move into the cavern. 

Nothing ventured, nothing gained! Thinks Eiren, plunging into the lit cavern. 

Wisdom save 12

(If the effect is a charming effect, I have advantage on saves to avoid it, so in case that applies here is the second roll 16. Also magic can't put me to sleep, if that is what this is :) Fey ancestry and all that)

(If the effect is a charming effect, I have advantage on saves to avoid it, so in case that applies here is the second roll 7. Also magic can't put me to sleep, if that is what this is :) Fey ancestry and all that)

 It doesn't actually say if it is a charming effect, but it acts that way, so I'm going to say that it is a Charming effect. It does not however put you to sleep (unless of course you die to the necrotic damage, then it is the final sleep)

Velmine moves to attack the Dread Warrior, but her rapier bounces off his armor. She then relies on her fancy footwork and cunning action to move out of melee. 

Eiren moves to where Velmine started from and sends and helping hand to attack the Dread Warrior. The hand is latched on tight.

Xavier takes 6 necrotic damage and you can make another Wisdom save. 

The Dread Warrior's eyes glow with pale light and it's posture changes, becoming more erect. It says in a loud voice "What are you doing in my Doomvault?" And then casts Evard’s Black Tentacles centered in L10. 

Baik and Corvin are up. At the starts of your turn, you must succeed on a DC 17 Dexterity saving throw or take 3d6 (Baik 11; Corvin 16) bludgeoning damage and be restrained by the tentacles until the spell ends. If you are restrained you can use your action to make a Strength or Dexterity check (your choice) against his spell save DC 17. On a success, you free yourself. 

Wisdom 16

Dexterity: 4

(Well Crap)

So you can talk, can you? I knew we had to focus on you! Let’s fix that mouth, shall we? Even restrained by the tentacles, Baik proceeds to smirk, as he summons forth a blaze of Flames to burn the Dread Warrior.

(DC 16 Dex save, or 34 . Half on a Success.)

He then calls forth more Sacred Fire to burn away at it. If the Dread Warrior dies, he instead targets the Wight (W1)

(DC 16 Dex save, or 12 Radiant damage.)

Xavier is jolted out of his trance at the end of his turn. 

Baik reacts to the damage he takes by sending hellfire at the Dread Warrior. The Dream Warrior casts counterspell[ and the fires dissipated. Baik then cast Sacred Flame at the Dread Warrior 

DW1 Dex save 17, but the Dread Warrior is able to avoid the holy fire.

Corvin is up 

Dex save: 7

(Dread warrior 1 and wight 1 are both within 15 feet of Corvin so would have been affected by Spirit Guardians on their turns.  DC17 wisdom save or DW1: 11, W1: 15 radiant damage.  Half damage on successful save.)

Corvin ignores the tentacles around him and strides forward out of the area of the spell to swing his hammer at the dread warrior's face.  His spiritual hammer follows to do the same.

(Move to P10)

Warhammer Attack: 19 Damage: 8 +  7 psychic damage (divine strike)

Spiritual Weapon Attack: 22 Damage: 9

Spiritual Guardians damage for enemies that start within 15 feet of me or enter that range next turn:

DW1: 15
W1: 9
Z1: 11
Z2: 8
Z3: 12
DW2 (just in case): 9

DW1 dex save 3

 At the start his turn the Dread Warrior is cut apart by Corvin's Spirit Guardians .

W1 is diced by the Spirit Guardians.

W1 Wisdom save 8 and just stands there. 

 Both Baik and Corvin are up again as I forgot about the Spirit Guardians. Baik you get your spell back 😀 Corvin the Dread Warrior is already dead

(Corvin will move to the same spot and just direct the attacks to W1 instead of DW1.   Spiritual Weapon can move to P9 to attack it)

Corvin moves to P10 and attacks the Wight (W1) with his warhammer, but the swing goes wide and he misses. 

He then directs the Spiritual Weapon to also attack the Wight. The Spiritual Weapon deals a mighty blow. 

W1 Wisdom save 13

The Wight's eyes snap on Corvin. 

Baik is up 

(Welp, I was going to use a Spell anyway, why not now?)

Baik moves down to N12, and points his magical weapon at the 2nd Dread Warrior (dw2). The last one was strange. Let’s prevent that, now! A small beam of Light Energy streams towards the other Dread Warrior, before it can pull shenanigans. 

Spell Attack: 13 Damage: 21 And next attack has Advantage on it

Baik uses his spear as a focus for a spell. The bolt explodes into the Dread Warrior causing it to it to disintegrate into dust.

At the start of their turns the zombies are targeted by Corvin's Spirit Guardians. They each take damage. 

Z1 Wisdom save 11

Z2 Wisdom save 7

Z3 Wisdom save 10

Z1 and Z2 just stand there. 

Z3 moves to Q10 and attacks Corvin with a Slam Attack: 7 Damage: 4. Still dazed by the spiritual mauling it misses. 

 Xavier, Eiren, and Velmine are up
