Hadrian makes two cutting motions with his hand and makes a divine utterance. A powerful spectral blade is conjured at 4th level, which is swinging towards Strahd even as it materializes out of thin air...

Attack: 26 Damage: 14 force

Hadrian follows up by calling forth the skeletal hand of Kelemvor against the werewolf Emil, attempting to kill the evil beast before it can infect anyone. 

Attack: 17 Damage: 7 necrotic 

(If there's another enemy within 5 feet of the werewolf, I'll target them too using my Reaper class feature, Attack: 21 Damage: 3 necrotic)

Hadrian's spectral blade hits Strahd as the hand of Kelemvor hits Emil!

Strahd uses his third legendary action to walk up the walls towards the ceiling without provoking an attack of opportunity.

Doremor will stay close to Samael and use his last first level spell slot to cast Tasha's Hideous Laughter on Strahd (DC 14 Wis save or fall prone and be incapacitated)

Wisdom: 18

Strahd doesn't find Doremor's joke funny.

Samael22,Hadrian22,Doremor21,Lair20, Hound of Ill Omen18, Fae16,Strahd13,Belzo10,Ismark9,Gertrude8,Emil5

Strahd summons a specter to attack Belzo.

Attack: 18 Damage: 15

 Conc. Save: Spending 2nd(/final) Divination Die, making the results 12+6+5(Pally Aura) for: 23.

Unable to reach its target, Bosco paces below whatever space Strahd currently resides above, growling and glaring up at the vampire. 

Grumbling about all the movement, Fae sends four bolts of light after Strahd.

Attack: 9 Damage: 5

Attack: 9 Damage: 6

Attack: 28 Damage: 10

Attack: 26 Damage: 7

 The first, third, and fourth bolts hit Strahd!

Strahd points towards Belzo! Make a Wisdom Saving throw.

Samael22,Hadrian22,Doremor21,Lair20, Hound of Ill Omen18, Fae16,Strahd13,Belzo10,Ismark9,Gertrude8,Emil5

Belzo is up next, let's see how that save goes!

Will Pally Aura Be Enough To Spare the Mad Sorcerer!?

Belzo's Wis Save: 14.

For just a moment, as the charm took effect, one old man's mind is taken back to the past. Back to the moment a certain Dragonborn researcher reached out desperately for his hand as their some dark portal threatened to suck them both into a realm of death and decay. "No... not again... I won't let it happen again." He mutters, squeezes his eyes shut for a moment. Turning back on the others with a look of determination, "I'm afraid I cannot allow you all to do this! Cease this conflict now, or else." As he says this, he points to Hadrian and tries to warp his being into that of a... Vulture.

In doing so, Samael would feel a wave of lethargy sweep through him so great, he can't muster the will to move..

Whether the spell takes effect or not, Belzo looks to his fast fading limbs and starts going, "No.. no.. Not now! Not again!" as he fades from existence.

Bonus Action: Converting a 1st level spellslot into a sorcery point.

Action: Ending conc. on Haste to cast Polymorph(Wis Save: DC 14) on Hadrian.

End Turn: Blink(DC 11): 12.

(Ah thanks for that!)

Hadrian WIS save vs Polymorph: 22

 Ismark drops his longsword, pulls out his heavy crossbow and takes a shot.

Attack: 16 Damage: 10

 He barely hits and it doesn't do much damage, but it's still more than Leo did in the last CoS!

Gertrude is up!

Gertrude, again, flies over to Strahd, helping the next person attack him before flying away.

 Emil attacks Samael!

Attack: 24 Damage: 8

If it hits, make a Constitution saving throw

Attack: 15 Damage: 10

Hadrian and Doremor are up!

Doremor reapplies his Hunter’s Mark to Strahd before firing an arrow at him.

Attack: 27 Damage: 24

Hadrian waves around himself and utters a dark incantation, and shimmering energy surrounds him in protective waves. His eyes follow Strahd up the wall and he sends his spiritual weapon after Strahd, making another attack against the devil...

Attack: 30 Damage: 12 force

(If the attack hits, Hadrian will Channel Divinity to deal an extra 23 points of necrotic damage, which ignores resistance)

 OOC: Well damn

Samael22,Hadrian22,Doremor21,Lair20, Hound of Ill Omen18, Fae16,Strahd13,Belzo10,Ismark9,Gertrude8,Emil5

Strahd uses his Lair action to pass through the ceiling, seeing as the battle is not favoring him at the current moment.

"Hold Belzo down!" shouts Hadrian. "I will expel the devil from him."

(Emil is here, you're all still in initiative)

Belzo fades back into existence, rubbing his forehead. "Hold off on that, Kelemvorite! Whatever magics or the like that 'devil' employed does not transcend the bounds of this plane." He espouses as he took in the scenery. Then his eyes falls upon Emil. "But  remain wary should he try again." He said just prior to unleashing black bolts of energy upon the man in rapid succession. Each one weaves past others as if they had a life on their own. One deep shadow stealing breathe later, and strength is regained.

Action: Belzo Casts (5th level)Magic Missile upon Emil, inflicting 4 x 7 plus 7 force damage for a total: 35.

Bonus Action: Convert a 1st level Spell slot into a Sorcerery Point.

Emil dies as Belzo pelts him with Magic Missiles. The six of you are now alone down here, with Strahd having fled the area.
