Zim is taken aback by the horrific scene. "Aye, what killed these poor unlucky souls? He moves into the room to check if they are alive or dead (or undead)"

Moving to M19 to perform a Medicine Check on the south most body 19

Durak does not mind the fetid waters as he steps into them. He quietly follows Zim and the rest of the party as he thinks separating at this point would be a bad idea. He lags behind as he considers the figures carved on the doors. Though his thoughts are interrupted by the smell of blood, and he frowns upon seeing the bodies.

Durak will take out his orb and says "If everyone is willing to wait 10 minutes, I can scan this area for any hints of magic" 

Barring any objections he will cast detect magic as ritual. 

"Ten minutes is fine with me," Sarris says casually.
   
"These hallways and rooms are a bit cramped.  I think I might change from a longsword to my handaxe and dagger for such close quarters."   

He sheaths his sword and pulls his pack around to dig out his handaxe and dagger.

Gorin takes a step back at the sight, but knows he probably should get used to it in this place so steps back.

"Knowing if there is any magic here sounds like a good idea."

Quote from Oberon99 >>

(If relevant, Stinger: 13 Piercing: 9 Poison: 7 )

 Despite Valeria's knowledge of infernal rituals and spells, these runes do not remind her of any that she is familiar with.
(Check is actually religion check)
The imp flies above the southern body and stabs into the corpse. It gives a spurt of blood and groans, followed by a swift shift of the corpse, swinging a familiar skull flail. The other two corpses do move as they rise up and point their hands at the imp.

Valeria is First

Mal screeches in pain as the skull flail crashes into him but he still manages to duck away from the attacks of the other two cultists.

Seeing her familiar assailed by the nasty myrkulytes, Valeria calls upon her infernal powers to place a hellish curse on the cultist at the back, then unleashing a hellish red beam of crackling eldritch force towards him.

(Hex (wis) Eldritch Blast: 25 Force: 10 Necrotic: 3 )

She then moves to the east against the wall and into full cover from the remaining myrkulytes.

 (Made a mistake on damage assigned. Was supposed to be (3) but forgot how I assigned the numbers for them.)

Zim barrels past the two cultists, ducking under the flails as they swing at him. He steps to the side of fire as he swings his morningstar, clotheslining the cultist with his weapon. The cultist is knocked down, dead from the blow.

 (Damage still killed though.)

Action: greatsword to hit 25, damage 9 slashing 

 (Going by movement, will change target to (1). And full switch will require dropping both flail and shield.)

Arkon charges into the room, slashing at the other cultist. He lands a heavy blow upon the cultist but they still stand as they swing their flail at them.

Flail Attack: 19 Damage: 5

Updated map -

Gorin is up

Gorin throws a javelin at the Necromite he can see right in front of him.

To hit: 21 for 5 dmg.

Durak stops mid chant and grips his orb tighter as the corpses rise to attack. He lets the magic dissipate as he recalls fire to his mind. With his left hand outstretched he shoots a fire bolt at necromite 3 

18 to hit 6 fire damage

Sarris shifts from one foot to the other trying to see the action in the next room while peering over Amory's shoulders.   

Once a clear glimpse of necromite #3 occurs, Sarris with launch a mote of light at the creature.

  Starry Wisp

To Hit:  22     Damage:  2 radiant    {game log}

The necromite gives off a dim light that helps illuminate the room... a little.

Mal turns invisible again and flutters to find a perfect angle for another strike, then as directed by his mistress he stings the myrkulyte again.

(Val uses action to allow the now invisible Mal strike Necromite 3 again, Stinger: 17 Piercing: 9 Poison: 7 )

Zim moves up to Necromite (1) and attacks with his morningstar

Zim targets Necromite (1), morningstar Attack: 18 Damage: 13, sap on hit

Arkon swings at Necromite 1 again.

Action: Greatsword to hit 23, damage 16 slashing
