Freya casts Etherealness on herself, steps into the Ethereal Plane, and simply walks across the distance of the Umbral Portal room to the other side of the room.  She'll reappear back on this plane right in front of the portal on the other side of the room.

Your spell fizzles, and fails. You find yourself exactly where you were before you cast it.

Freya yells out in Infernal "MOTHER EFFER!  That didn't work.  Screw YOU, Umbra!"

OOC: Question for Crispy- How long (in-game time) has it been since we fought the Umbral Souldemon dude in "ROOM TWO - UMBRAL SOULCAGES", post 429?

He doesn't speak Infernal. Also, about an hour.

"Shut the **** up, idiot." Madison says to Freya, "What are you trying to do?? Get it's attention?". She looks up into the sky, discretely points to Freya, and mouths the words 'kill her next' to some unseen power.

The tentacles have a reach long enough to the edges of the room, and will attempt to grab anyone who tries to make it across. Anyone who wishes to try and make it across must pass a DC18 DEX save to not get grabbed. If you DO get grabbed, you need to pass a DC18 Athletics check to wiggle free of the tentacles. If you wiggle free, you make it across. If you fail to wiggle free, you get thrown into the pit of infinity and are out of the game, lost forever in the fractal of madness. Since the room is square, you are in reach of two tentacles, so much make two checks (DEX and/or Athletics) twice. The tentacles are extremely swift and strong, so cannot be attacked in any way, as in to free someone who is grappled. 

Villanelle casts Bless on herself, Father, Madison. "There. Don't say I never did anything nice for you, Von Schmiggleton."

Extra d4 from Daddy:  2

Tiger Tora approaches the room, tilting her head with a slight growl before pacing back behind the group. After a moment of pacing back and forth, she bolts forward and past the group, lunging with a jump towards the walls before bolting her way vertically, her paws and claws thudding and scraping the walls as she attempts to outrun and out dodge the tentacles.

Bless for whichever is lower: 1

Guidance When needed: 2

Dia pokes her new soul's cage. "You're helping me here, dear." Two ribbons of dark blue fire stream from the soul and into Dia, who smiles grimly and sets off across the pit as soon as she's been blessed and guidanced and such.

DEX2 24 + 3

Father blesses his other compatriots before they make their way across, followed by Guidance when needed. "May Umbra guide you well~" When it came to his turn, the tentacles, despite their malicious intent, don't seem to bother him, and whether or not he gets dragged into the abyss, he is seen ever so widely smiling.

Dex: 18 + 5
Assuming I survive the first one, here's the second dex: 22 + 2

Exelda would pull up to the new room with the others. She'd cross her arms and tap her foot as she looks around anxiously. LeBlanc would take a look over her shoulder to Father, "Even if your God doesn't have your back for this one, I will."

Casting Bardic Inspiration on Father 1 D10

Releasing her arms down to her side, the blade master will shake them at her side to loosen up. She'll bounce up and down to try and psych herself up. When it was her turn, she'd back peddle a little bit and pause to suck in some air. With a hop, she'd skip off into a trot to reach the ledge, kicking off into her first leap, following the tigers lead.

THE UMBRAL PITS, LEVEL TWO
ROOM 5 - THE MAGNETIC CHAMBER (Room at the bottom)

This 30' x 30' room has 15' walls. It's well lit by purple flame torches set in wall sconces. There are four black stone doors other than the entrance, one in each corner of the right and left walls. Directly opposite the entrance is a highly polished 10' square metal mirror. The entire room is extremely clean.

Vulcan examines the metal mirror, curious to his own reflection, as the last time he saw himself, was......well, he didn't actually remember. He checked his teeth before walking over away from it and checking purple flames, attempting to see what kept them lit.

The mirror turns completely black and you head a horrible humming emit from it. You slam into it, front first, unable to turn around. You are considered paralyzed. 30 bugbears, twisted and grotesque with eldritch features, erupt from the side doors and attack everyone in the room - their inhuman screams rattle your minds.

MAGNET WALL
Anyone else wearing any kind of metal armor (shields don't matter, they can be dropped) at all feels drawn to the wall with the mirror. It's acting like some sort of terrible magnet. Vulcan is stuck to the wall so cannot act and is at advantage to be hit. Everyone else who is wearing metal armor must pass a DC20 STR save each round in order to act normally or trip up and get pulled to the wall. If you fail, you're stuck, unable to act at all till the end of the encounter and have advantage against you to be hit. If you have a clever way to use a spell run it by me first and i'll say yay or nay if you're stuck on the wall.

Strength:30

Being stuck to the wall, along with his cannon, Vulcan grits and lets out a defiant scream. Not one to take it lying down, he does what any rational, and sane person from his family would do....he self destructs.

Cannon Self Destruct: 11 force damage

Vulcan's cannon explodes, and fills the room with a deafening nut blast.  Vulcan you take 8 damage, and the mirror remains unbroken.

Everyone else who's wearing metal armor, lets go, lets have that save roll.

Stfu crispy: 10 + 4 + 5

”This is a very nice mirror... I wonder if I could replicate this in the church... Hmm...”

Nice thoughts to have while your cheek is pressed against the wall.

Ok, initiative time. I'm going to roll for the bugbears as one big group, because none of you sacks have to type all this shit out, so here we go.

Bugbears: 21
Madison: 12

AOE spells will hit EVERYONE, including friendlies, for this fight.

Villanelle: 7
