Storm King's Thunder

Don takes his daggers and attacks the creature as he drops to the floor and runs. "Good luck Ink. Hope I'm not making a mistake."

Attack 1: 17 Damage: 8
Sneak Attack: 11

Attack 2: 19 Damage: 6

Disengage and run!

Ink collapses unconscious after the claw attack. 

// Since Don is opting to not disengage and instead attract an opportunity attack... //

The demon once again lashes out in retaliation, this time at Dontontion...

Claw Attack Against Dontontion: 28 Damage: 10 slashing plus 20 necrotic

As Don flips off the creatures chest it's claws rake his back, deep gouges appear. He twists to one side and you can tell what might have been a deadly attack merely is incredibly painful.

/Uncanny Dodge/

Seeing  an opening, Flint says "the way is open Crownsguard, let's go!"

Flint casts healing word at ink ( 5 ) then [spell]sacred flame[/roll] on the demon (dex dc14 or 5 radiant) before moving into the main room.

As Don runs past the dwarven ghoul, it also reacts with a claw slash...

Claw Attack Against Dontontion: 17 Damage: 6 slashing. On a hit, please make a DC 10 Constitution saving throw.

Con Save: 16

Ink breathes in a sharp breath of air, a panicked expression on his face. He buries a feeling of hopelessness lingering on his soul...

"Kill me once - shame on you. Kill me twice - shame one me. I'm out. Good luck, Crownsguard. Fallback if you can - let's wear him down at range," Ink states.

He steadies his footing in the demon's rib cage and thrusts up with a booming blade! Not waiting for the fallout of his action, Ink disappears in a silvery mist and reappears thirty feet due south behind the alter and steps back another fifteen feet.

// Booming Blade Attack: 10 Slashing/Thunder Damage: 15, plus 3 thunder damage if it moves on its own //

The main room of the temple is still empty, devoid of worshippers this early in the morning. However, those closer to the doors will hear a commotion outside.

Inside the altar room...

The unconscious body of the High Hammer vanishes into the chest cavity of the demon, and the creature quickly uses its wicked claws to end the life of the poor priest. It seems to imbibe the blood flowing from the dead dwarf, gaining strength from it.

The devourer takes a second swipe against Crownsguard...

Claw Attack Against Crownsguard: 14 Damage: 12 slashing plus 21 necrotic

It then marches forward into the main worship area, looking seriously wounded, but slowly regaining strength, and again washes the room in dark energy: everyone in a 20 foot radius must make a DC 18 CON save, taking 64 necrotic damage on a failed save, or half damage on a successful one. 

Crownsguard is knocked unconscious and fails a death save.

Ink watches the sphere of necrotic energy wash its way through the temple stopping just in front of his eyes....

When he looks on as the negative energy dissapates, the carnage horrifies him. 

Con save: 17

Down

Con Save: 11
Hellish Rebuke: 21

//Ignore Rebuke if this isn't a new round as I used my reaction last round. And yeah I know it is resistant to fire./

Don is down.

Death save: 14

Quote from Hardcopi >>

Hellish Rebuke: 21

 The spell seems to cause the monster considerable pain, although you can tell that it wasn’t quite effective as you’d have liked.

Death Save: 1

The devourer lets out a shriek of triumph. 

No sooner does the necrotic wave pass over the room than the temple doors are flung open and about a dozen members of the Axe of Mirabar, humans and dwarves, enter the worship area with their shields up. 

Their back ranks have crossbowmen, who fire off their readied shots, no questions asked, as soon as they see the rampaging demon. In their haste most of them miss, though one bolt sticks in the devouerer’s neck, and its triumphant shriek turns into one of pain.

The dwarven ghoul bites into Matrix’s downed form...

Bite Attack against Matrix: 6 Damage: 11

(Attack with advantage: 10)

...just before a crossbow bolt takes him out of the equation, permanently.

Crownsguard Save: 16

Matrix save 13

Ink, on the verge of hurling a fireball to keep his friends' souls from being absorbed by the demon, steadies himself and cries out:

"HEAL THE UNCONSCIOUS OR THE DEMON WILL TURN THEM INTO UNDEAD!"

"BRACE YOURSELVES - THIS BEAST CAN SHOOT NECROTIC ENERGY OUT TWENTY FEET!" 

Then in a whisper, "While they're breathing  there's hope. Moradin protect my friends."

Ink goes charging in yelling at the top of his longs, his bladesong kicks in and beneath the screams of anger a harmony joins the pained yell. The ruby of the war mage begins to glow, brighter and brighter. Ink leaps onto altar and in a final enraged yell with the red ruby bright he viciously clangs his two adamantine scimitars together. The ruby goes dark and before the ringing of the blades get their first echo a massive clap of thunder erupts from their point of contact focused squarely on the demon the force of which almost sweeps Ink off his feet. He squares off against the demon and growls, "LET'S SEE YOU TRY TO STEAL MY SOUL YOU SCUM OF ORCUS!"

// Thunderwave at 3rd level.... 28 thunder damage, DC 15 CON Save for half and to avoid getting pushed back ten feet... //
