Drusk suggests: "Let's head back east, and turn north to continue exploring. If we see another chamber, we should stop before entering, in case of traps. (Unless there is another floating monstrosity inside that will cause Jorin to charge.)"

Jorin pockets the locket and wraps the sill scarf around his neck.  He walks over to where Pascal is field dressing the spectator corpse, and with a hearty laugh says, "The only thing better than besting an enemy on the field of battle is eating him afterwards!' 

He gives the lizardman a firm, good natured slap on the back and then follows Drusk towards the exit of the room, soft silk billowing off his neck with each step.

Hildigrim opens his mouth to inquire further with Pascal, but Jorin's question about the bracelet steals his attention. He catches the bauble, and as Vanja hands him the torch, he uses the light to scrutinize the design.

13 (history or arcana +4, religion +2)

Once everyone is ready to proceed, he takes the lead, going where Drusk had suggested and continuing to watch to trouble.

Investigation: 10

OOC > Nothing much to react to last turn, so I'm gonna give you all the next waypoint and then we'll take a day or two for the Christmas holiday (in case you celebrate that) for everyone to get a bit in. Hope you all are being merry, but if this time of year is hard for you, please reach out to someone (or me, if there's nobody else, I have some training and am happy to listen).

The group takes a collective moment to look over the loot, combining your various expertise. The bracelet is most likely of elven design, Drusk confirms, but has no obvious religious or other meaning. Most likely art, maybe sentimental. The two imp statues are well carved from some sort of bone, clearly a set, probably for or by someone who favors an infernal or demonic approach to life. Imps are evil, several of you agree, so the intent of these was probably to favor evil. The locket is clearly a personal prize for someone, the Tiefling woman painted inside, though the painting is old, is quite beautiful, but nobody recognizes her or the handiwork. Most likely another personal item. And the silk scarf is in remarkably good condition, light blue with strong red piping on the edges. Soft but sturdy. It goes well with Jorin's tattoos. :)

As you  are gathering yourselves, one of the large pieces you shifted slips and clatters to the ground, making a loud noise that reverberates through the halls. It's not much noisier than when you all were shifting the pile in the first place, but it reminds you of where you are, and that the dungeon is not completely explored yet.

Hildigrim and Jorin take the lead once more, moving back down the hall to the main passageway, where Hildi prepares to begin scanning the floors and ceiling carefully with his torch and Jorin's axe-light. You reach the intersection and head north, Hildi peering all around, and Jorin looking ahead.

But as the party approaches the doorway to the room ahead, Hildi is pulled up by Vanja's cry (high passive perception, not staring at the ground). Stopping suddenly, the group peers north and sees... something very strange.

At first, it appears to be a floating coin about ten feet away in the room, glinting in the light. Then you see three or four more, seemingly floating in midair. As Jorin lifts his axe to see better, the coins lurch towards you, and you gasp in horror as you realize that the entire hallway is filled with some sort of transparent... thing, and that the coins are being carried along with it. Inside it!

As you watch, horrified, it slurps its way towards you, filling up the entire passageway, top to bottom, side to side.

Party vs. the Entire Hallway Monster
Round 1
Declaration Phase

Map: (and a link to the full dungeon map at this point)

Sitrep: You stand in the hallway, and the thing is moving toward you, slowly.

Drusk - AC 18 - 10/10 hp
Hildigrim - AC 14 - 6/9 hp
Jorin - AC 17 - 12/12 hp
Pascal - AC 14 - 10/10 hp
Vanja - AC 12 - 10/10 hp

Entire Hallway Monster: It does not appear injured. How would you know if it was injured?

Monsters declare! The monster is moving south towards you. It is making... sinister slurping noises?

Next: Everyone please declare. As a quick reminder, that means you tell me what your character intends to do in the next six seconds, you roll for those actions, and you also give me an initiative roll, just in case. Then I resolve it (cinematically!).

• Declare Delay or as many of Action, Move, Bonus Action and/or Reaction as you want
• Roll initiative
• Roll for your declared actions (to hit, damage, etc.) if any
• Concurrent Initiative explainer: https://www.dndbeyond.com/campaigns/277586

OoC - loved that recap!  Also, I can totally imagine the gross, wet, sucking sounds reverberating through the passage.

Drusk: "If it was happy slurping noises, we could let it live. But sinister slurping noises? Perish!"

Drusk casts Sacred Flame (DEX save DC 12 or 3 radiant damage), then moves south to keep a 30' distance from the jello-from-hell.

(Edit: Forgot initiative. 17 )

“If everyone could step behind me, merci beaucoup. I’m about to flambé whatever comes down this hall.”

Pascal will let loose a Burning Hands for whatever comes down that hall, DC 12.

Initiative: 20

Fire Damage: 10 Fire Damage.

Jorin smiles at Pascal's request and will take a step behind him before drawing his blunted handaxe and throwing it at the cube.  Attack: 18 Damage: 3

Initiative: 6

Once again, someone has to jar Hildigrim out of observational paralysis.

Investigation on the creature — what is it?!: 20

At Pascal's words, the halfling back pedals to allow the prestidigitator to attack. When at a safe distance himself, Hildigrim decides to try piercing the unknown danger with a perfectly placed projectile.

Shortbow attack: 11; damage: 6 piercing damage

OOC > While we're hanging out, Roll Call! Can I get everyone to roll a d20? I'll adjust with appropriate modifiers from your character sheets, if needed. :)

Also, it does not look like this:

DM sekret rollz...

Party vs. the Entire Hallway Monster
Round 1
Resolution Phase

Starting Map: (and a link to the full dungeon map at this point)

Resolution: 

As the party stops in horror at the thing in front of you, Pascal reacts quickest. "If everyone could step behind me, merci beaucoup." Everyone scrambles backwards, Jorin, tugging Hildigrim along, as the massive wall of goo slides towards the group. The red lizard man stands tall, puts his hands together and incants, and a stream of fire flows out at the creature, which makes a sudden stop and slurps back a foot (Dex save 16!), taking the fire but missing the full brunt (5 dmg).

Drusk, from behind Pascal, says "If it was happy slurping noises, we could let it live. But sinister slurping noises? Perish!" and calls down the joyous fire of Lliira, catching the thing as it fills the space back in (save 0), with radiant fire (3 dmg).

Pascal turns to retreat with the rest of the party when he stumbles and clutches at his head (rando d20 was an Int save resulting in 1), howling (6 dmg), from an unseen assailant, but he continues down the hallway.

Hearing the cry, Hildi, Vanja, and Jorin turn from their flight and launch attacks. Hildi's arrow strikes the quivering wall (8), sinking into the jellied mass (8 dmg), and Jorin's axe sails true (22), slipping inside the jelly (6 dmg). But in her haste, Vanja lets the ball of flame slip (critical 1), and it flares out on Jorin's feet (1 dmg).

The wall of transparent goop continues towards you sedately, shuddering at your attacks, but then surges down the hallway towards you, sliding and squelching along the walls, floor, and ceiling!

Next: Round 2! I'll post a declaration phase in a second.

Notes: Never expected the Cube to roll a 20 on a Dex save, but even with a -4, resulting in a 16, that's a save.

Party vs. the Entire Hallway Monster (and friends?)
Round 2
Declaration Phase

Map:

Sitrep: You have raced down the hallway, easily outpacing it, but turned to attack it as it continued its inexorable charge. Hildigrim ran as far as his legs could carry him before turning to shoot at it, and Drusk and Jorin were unwilling to leave him behind. The smell of boiling muck fills the air.

Drusk - AC 18 - 10/10 hp
Hildigrim - AC 14 - 6/9 hp
Jorin - AC 17 - 11/12 hp (Vanja's crit miss flame out)
Pascal - AC 14 - 4/10 hp (mental attack)
Vanja - AC 12 - 10/10 hp

Entire Hallway Monster: It contains a new arrow, a new hand axe, and some of it may have sizzled off, but it seems fine.

Monsters declare! The monster has just dashed down the hall towards you, and seems intent on continuing its advance. Also, something blew Pascal's mind!

Next: Everyone please declare. Let's add a random d20, that has been useful.

• Declare Delay or as many of Action, Move, Bonus Action and/or Reaction as you want
• Roll initiative
• Roll for your declared actions (to hit, damage, etc.) if any
• Roll a random d20 for my use
• Concurrent Initiative explainer: https://www.dndbeyond.com/campaigns/277586

Jorin chuckles at the singed tip of boot and upon seeing his handaxe havjng bit intothe cube, roars and charges up (left 1, diagonal left/up 1, up 1).  He draws his second battleaxe as he charges an lays into the creature, cleaving chunks of jelly with every blow!

• Action: Attack: 6 Damage: 6
• Bonus action: Attack: 9 Damage: 4
• Initiative: 19

Edit: oof

Drusk gives it a bash with Joybringer. Mace Attack: 18 Damage: 8

While Drusk would like to back up more, he sees Jorin running towards the side room, which will leave him trapped soon. Maybe this is the place to draw the line.

Initiative: 6  Basic d20: 16
