Lost Mine of Phandelver

Marcon shares a look with Rigel before proceeding further down the hallway. Or at least, as far as the door on the northern wall, which he'd continue on just a little further past before stopping and gesturing back to it. Assuming at least one other kept pace enough for him to be able whisper to, he'd say while focusing his gaze again back on the chamber. "Someone mind checking it out. Just in case? 'cause I don't know 'bout ch'all, but not sure we want some'n burst in behind us once." 

Peering into the chamber, Marcon sees six cracked marble pillars lining the walls. At the north end stands a nine-foot-tall statue of a dwarf seated on a throne, a mighty stone warhammer across his lap. Large emeralds gleam in the statue’s eyes. Dust and debris covering the floor has been swept to one side, and a campsite of sorts now spreads in front of the statue. Half a dozen bedrolls and packs are neatly arranged around a rough-built fire pit. A wooden table stands on the west side of the room between two pillars. The chamber appears to be empty, but from his position, Marcon cannot see around the corners at the end of the hallway past the door.

The door in the hallway is locked.

Perception: 12

Rigel motions for the rest to join Marcon as he checks the door. Finding it locked he listens to see if he can hear anything. 

Rigel hears soft voices on the other side of the door, but he is not able to determine if they are friendly humanoids or more bugbears

Rigel indicates to the others that there are beings behind the locked door. He then moves his hand in a flat circular motion to indicate the other party members. He then motions for them to check out the room while he watches the door.

Just to be sure, Garet focus on his inner firbolg'ness and casts Detect Magic and for next 10 min will fallow the group and focus if there is any magic in the area

Standing in the stairwell, Garet does not sense any magic within range, other than the items held by his companions. He continues to concentrate on the spell, reciting the words of his incantation over and over again in his head as he looks around for the telltale blue glow of an enchanted item, environmental feature, or person.

Ronk creeps to the end of the hall to look into the chamber, peeking around the corners.

Stealth: 9

Drawing upon his bugbear heritage, Ronk crouches low standing on the balls of his feet in an attempt to proceed silently. He takes a few steps forward and plants his foot directly on top of a fleeing mouse. The tiny creature lets out a loud "squeak" just before its body is crushed under the weight of the towering monk.

The sound echos off the walls of the subterranean complex for what felt like miles and the others turn to look at him with faces that seemed to convey another sound: "Shhhhhhhh!"

Vanzaren winces at the noise, his sword halfway out of it's shieth. He side-eyes the locked door, listening to see if anyone inside is reacting.

Vanzaren notices that the voices on the other side of the door gather slightly at the sound of the dying mouse...while he cannot understand what they are saying, he is fairly certain that they have qualities of humanoid voices...low and gruff, with lots of hard consonants but with the inflection of perhaps one of the goodly races...definitely not drow though, with their more flowing syllables and minor tones that made their elvish speech sound like that of a funeral dirge being spoken aloud.

With how exhausted Marcon was, Rigel's hand signals might as well been spoken in ancient elvish. So there had been a lot of confused staring and head scratching 'fore the mouse echo finally drew his attention to the chamber, and by extension Ronk. Not wanting to add to the embarrassment, the ex-farmhand at the bugbear, glances back one last time to the others, and then shakes his head and step up to the end of the hallway... and five feet more out into the chamber to look around for any signs of ambushers.

The whole while not bothering with stealth, half figuring it to be pointless at that point, especially with his torch still in hand.

Perception: 4.

And if he does spot/hear someone(or thing), well... it depended. In the case of a bugbear, he'd at least look directly at their hiding spot and call out to them goblin, telling them flatly the jig was up and that they might as well and come out to talk.

If he fails to take note of anything however, he'd call out again in frank tones, "Look, I know ya'll in here. So ya'll might as well come out for a chit'chat. 'cause if I gotta find ya'll butts, my foot is going right up it." 

Intimidation: 4. 
(if applicable and assuming he even gets that far. xD)

From behind him, the others could see Marcon's lithe, muscular frame perfectly silhouetted against the firelight pouring in from the chamber and down the darkened hallway. They watched as he slowly stepped past the threshold of the hallway and into the chamber proper. He scanned the perimeter of the room and found a heavy door centered on the southern wall. The farmhand issues a verbal warning, and though no reply comes back to him, he couldn't shake the sense that it was all just a little too quiet...

He stands there, baffled for a moment, looking around...he notices that the table opposite his position is strewn with notes and large maps. A large, elegant-looking feather quill - one that is much too fine for this dungeon - stands erect from a bottle of ink surrounded by several other various glass tinctures of unknown contents and small handheld instruments. A shiny brass compass, glints in the firelight. He then notices a map case, not unusual in its construction, but one he felt he'd seen before...

It was then that a few tiny drops of blood splashed down onto the slope of his chest. Marcon puts a hand to his face to check himself for a nosebleed, but finding none, the reality quickly dawns on him...Marcon jerks his head back to look at the ceiling and the image that greeted him is one he would not forget for some time after that: four giant spiders, each as big a merchant's wagon, clung from the stone ceiling 20 feet above him, each holding aloft a scowling bugbear...a few more drops of blood fell from one of the goblinoids, staining Marcon's grizzled knuckles...

From the hallway, the others watched as four screaming bugbears came crashing down on the farmhand from above and then, to their horror, four enormous spiders lowered themselves slowly, suspended by strands of silk twice as thick as a rope...

Van moves like he's drawing a knife from his belt, throwing it at the spider in the center. A mass of ice forms into a knife, spinning towards the beast and exploding on impact. In the same fluid motion, he draws his scimitar and the song begins. He follows up his icy 'knife' throw with one made of fire

Vanzaren's ice knife explodes into an ice grenade upon impact with the giant arachnid, showing most of those nearby with needle-like shards. A few of the others are able to safely dodge the projectiles.

SPDR 1
The spider turns and rears forward onto its front legs revealing the spinnerets on the back of its abdomen and lobs a mass of webbing at Vanzaren:

Attack (Web): 19 vs. AC 14 (Vanzaren); rendering the target restrained on a hit.

(OOC: A restrained target may use an action to make a DC 12 Strength (Athletics) check, bursting the webbing on a success. The webbing can also be attacked and destroyed; it has AC 10, 5 HP, vulnerability to fire damage and immunity to bludgeoning, poison, and psychic damage).

Two of the bugbears quickly rush in to surround Marcon:

BGBR 1
Attack (Morningstar): 11 vs. AC 18 (Marcon); dealing 10 piercing damage on a hit.

BGBR 4
Attack (Morningstar): 12 vs. AC 18 (Marcon); dealing 10 piercing damage on a hit.

Garet will try to shoot visible (for him) spider with his crossbow:

To Hit: 18
DMG: 9

From his current position at the bottom of the 10-foot long, 5-foot tall staircase, Garet can barely see into the melee unfolding in the room to the east, but he has somewhat of a clear shot on one of the giant spiders. The firbolg shoulders his crossbow and fires a bolt in that direction, which sails high and out of sight, thunking soundly into the table at the far end of the chamber.
