Jade's CON save 22

Oops, I presume Jade is by the Cave entrance.

Lux says "Is anyone severally hurt, besides Jade?"

If none close by he will dash towards Jade. If needed - An Opp Attack against Lux would be made at disadvantage from Warding Flare. Also, at the beginning of the bad guys turn, they will 1) lose half their speed and 2) need to make a WIS 16 Save or take 14 radiant damage. Save for half. 

If anyone close, then he will cast Cure Wounds at 1st level, and then move towards Jade.

((Liri is about half health, but she's in better shape than Jade. She also still has a few spell slots left so has some cure spells of her own still))

Just to confirm, Lux dashes towards Jade.

@Lux

You run completely at Jade, taking an opportunity attack along the way. Ghast 12 makes an opportunity attack with disadvantage from Warding Flare
Attack: 8 Damage: 8

Also, you are too far way from Ghast 12 for spirit guardians to take effect and the ghouls already moved (and were too far away from you for Spirit Guardians on their turn), so none of them are effected by the spell

You end your turn in the middle of the moat, and you can feel the water creeping up your legs and singing your flesh. Make a Con save

@All

Vyldara flies undergound to between Soloth and the real Elandra, and then emerges. She goes to continue casting Vampiric Touch, but is silenced by Elandra's magic. Severely weakened by the spell and unable to do much real damage, in a fit of rage, she uses her corrupting touch on Elandra, hoping to break the silence around her. 
Attack: 9 Damage: 10

@All

Elandra, I beleive that knocks you down to 0 health, so there's no need for a concentration roll, but if you have a way to avoid taking that damage, then a concentration roll for silence is needed

The ghasts then attack the nearest person to them, hoping to deal as much damage as possible
Ghast 7 swings at Norbus (damage halved, taken by statue as well)
Attack: 17 Damage: 8
Ghast 9 runs to the statue and takes another swing at it
Attack: 12 Damage: 13
Ghast 11 takes a dash action and rushes fully to behind Jade, trying to block her in
Ghast 12 rotates around to take a swipe at Dazlyn
Attack: 24 Damage: 12

At the end of the Ghast's turns, Vlydara moves 5ft NW and 35ft N (this movement does not provoke opportunity attacks), but remains above ground 

@All

All three ghasts miss the enemies they are trying to attack. Koric is up! Map Update:

Lux CON Save 19 (Advantage from War Caster)

@Lux

You resist the toxic effects of the water, unphased by whatever it is trying to do to you 

Koric moves 20' north as arcane energies swirl around his hands and, finally able to see Velyndra again, he launches a three more bolts of energy at her.

Magic Missile 9 force damage.

At the same time he asks Balthar to assist Liri again, if possible, otherwise whoever is nearest.

@Koric

You rush forward and fling a few bolts of energy at Vyldara, and while she does not resist the damage, she seems relatively unphased by it, although her highly injured state is becoming more apparent

@All

Noticing Elandra be downed by Vyldara's touch, the statue spings into action. It takes a disengage, rushing away from the ghouls and ghasts around it and moving 30 feet towards Elandra and Soloth. As a bonus action, it channels the might of Moradin (Channel Divinity) to use Turn the Tide, healing itself and @Elandra for 4. As Soloth is above half his max HP, it does not effect him

At the end of its turn, it heals Elandra for another 2 hit points off of Aura of Vitality. Jade is up!

@DM - I have a cutting words reaction left, however it doesn't work against Vyldara as banshees are immune to charmed condition. I'm operating that Elandra knows undead are mostly unaffected by her spells. So she dropped and came back up, so silence has been lost and I'm up with those two minimum heal rolls :)

Seeing herself surrounded again, she uses her lay on hands and gives herself the full 25 hit points.

 Then casts shield of faith on herself, upping her AC to 19

Jade heals herself for 25 in total and attempts to shield herself, preparing for incoming attacks. Liri is up!

 Liri will use her last remaining wild shape to shift back into a Dire Wolf as a bonus action (due to combat wild shape). She will then launch herself with a snarl at ghoul 24, biting down savagely

Attack: 17 Damage: 10 (If it hits, the ghoul must make a DC13 Str check or be knocked prone)

@Liri

You wild shape into a dire wolf again, attacking the ghoul. It takes a heavy hit, and staggers back, trying to catch its balance
Str Save:15

Norbus moves out the way of Liri's new wolf form and continues to attack the catacombs, hoping to take them down. 
Attack: 23 Damage: 11
Attack: 15 Damage: 10

@All

Note: Above action was Dazlyn, not Norbus

The ghouls narrowly avoids being knocked prone. Dazlyn deals a heavy hit to the catacombs with his first strike, but the second one seems inneffective at doing anything at all, and the walls of the catacombs are still standing. Soloth is up!

(( Just realised that Balthar is assisting Liri, so that last attack should have had advantage. Rolling another d20 just in case it's a crit: 

10 ))

Elandra staggers to her feet, nodding her gratitude towards Soloth as he removes the potion from her lips and speeds offf away from Vyldara. Too late to encourage him to stay and fight the banshee directly, she moves herself into a better position. "You don't like the sound of silence, fine. Listen to this then!" She faces the banshee and in mock imitation of a banshee wail, she starts a scream that quickly turns into distorted laughter and cackles, the whispers of the sound fly at Vyldara.

Elandra's double whistles to the weasel and indicates the open shaft, as she mimes knawing at something with her teeth. She then moves up herself to stand below 12.

Action: Dissonant Whispers 3rd level @ Vyldara. DC 15 Wis, save for half damage only - 20 psychic damage, use reaction to move directly away as far as movement allows

BA: Command weasel to attack the shaft

Movement: 20ft NW, 10ft N
