The sound is coming from one of the 3 doors on the left. The first door tested by Lola is locked.

Edward leaves the closet and tries to head towards the sound; if he gets to the door where it's coming from first, he'll slowly and quietly attempt to open it.

Stealth Check: 18

Ed slowly opens the door revealing a horrifying scene. Its de Mendoza feasting on Trinidad Rizo. He turns when he sees the light from the flashlight ready to kill.

How does you characters react? Perhaps Lola is not used to seeing bloodshed and may react out of fear.

From combat I am going to use Side Initiative where the enemy side goes and then the party or the other way around.

de Mendoza - 15

The Party - 8

de Mendoza rushes to attack Ed and slams the door wide open.

He tries to Grapple Ed - Athletics - 20

Ed please roll athletics or acrobatics

James Wis save: 19

Edward's Rolls:

Acrobatics Check (DC 20) - 8
Wisdom Save (Sanity, DC 14) - 6

*double whimper*

Sanity Loss: 2

de Mendoz grapples Ed and then bites into his shoulder with his salivating mouth full of needle like teeth.

Attack: 25 Damage: 4 piercing damage

Plus 11 necrotic damage

Somehow Ed is able to not be bitten

Now its the Party's Turn

Ed can roll athletics or acrobatics again to see if he can break out.

de Mendoza athletics - 23

Wisdom roll= 6

Lola squeals and jumps back. She pulls out the elixir of boldness from another pocket and chugs it back, gasping with the fire of the alcohol going down. (She rolls a d4 and adds it to attack/saves for a minute. Rolled a 4 in character sheet)

Sanity loss = 1 

(( Ed's Acrobatics Check: 21 ))

James' dark eyes goes briefly wide as he sees the Mendoza-creature hunched over the missing student. He had seen his fair share of horror and even things he could not explain while in the trenches in france, but this sight gives the british gentleman brief pause before his instincts take over, his eyes searching out something with which he could kill this abomination.

Eye for detail bonus action perception: 11

(Maybe he can even see and get hold of one of the many weapons Ed is carrying ;-) More to come when bonus action is resolved)

(( @Oberon99 - Ed's revolver is openly strapped to his side, with a simple snap keeping it in place. However, his blades are all concealed on him. Have James do with that info what he will. ;) ))

"What IS this thing?!!" yelled Edward angrily as he struggled against the monster, startled for the first time that he could remember in years.

Unable to immediately break free from the creature's grip, the desperate young man did the only thing he could think of and twisted his wrist to aim the flashlight into it's eyes.

(( Hopefully that'll do *something*, either giving an advantage to someone or a disadvantage of some sort to de Mendoza. If not, Ed will have to wait until next turn to get his wits about him and strategize. ))

The flashlight will be Ed's help action for whatever James do next.

Noticing the revolver at Ed's side, James reaches down to snatch it, sticks the barrel into the toothy jaw of the Mendoza-abomination and fires, all in one swift motion.

Revolver with advantage due to the Mendoza-abomination being distracted by the flashlight: 15
Piercing damage: 11 + 3

Round 2

de Mendoza lets out a cry of pain as there is a bullet wound in his mouth, but everyone sees his flesh knits back together almost erasing all the damage from the bullet.

He once again tries to bite Ed

Attack: 16 Damage: 8 piercing damage.

Plus 9 necrotic damage

Now its the party's turn.

Ed you can feel your fat being drained from you as de Mendoza slurps it up.

Athletics - 5

Ed you can try to break out with athletics or acrobatics

Without thinking, Edward used his hidden ability to try to deflect the monster's bite.

REACTION: Using Protective Field (his is invisible) to expend a Psionic Energy Die and reduce the damage by 4

It was then, after he realized that he had used his ability in front of others that he shook his head and gathered his wits about him. Praying no one noticed the odd movement in the middle of the chaos, he clenched his teeth, redoubled his efforts to free himself, then stepped back to produced a dagger from his person, and thrust it towards de Mendoza.

ACTION: Acrobatics check to break free - 10
SURGE: Using Action Surge to draw his blade and attack de Mendoza
* Dagger Stab - Attack: 21, Damage: 7 mundane piercing (add an extra 3 on a crit)
BONUS: Use Second Wind to recover 10 HP (if allowed, flavoring it so that if he's back at full health, his initial telekinetic block stopped the attack)
