The BFOAGWGH

Ro stows her daggers and pulls out her scimitars, holding them both in one hand. She closes her eyes and takes a deep breath.

I am made of rage. I swing it like sword and wear it like shield.

She opens her eyes and reaches out to yank the door open. Then she grabs the second scimitar with her free hand, snarls silently at the opening, and runs through as soon as it's wide enough to squeeze through. If there's anything that appears hostile on the other side she'll leap straight at it and attack.

1st Attack: 13 Damage: 7

Offhand Attack: 11 Damage: 4

Xiaolong follows promptly that little ball of fury, really impressed. Expecting skeletons, she draws her sword and enter the room.

Initiative 17

Shortsword Attack: 16 Damage: 5

Unarmed strike Attack: 21 Damage: 5

On the other side of the door, you see old stone bunks in orderly rows lining  the walls, and a corroded iron brazier full of old coals stands near the middle of the room. The bones of a half dozen dwarves and orcs lie strewn about, clad in scraps of armor. A gray, hunched figures squats among the remains, pawing at the scraps and gnawing on the bones. At its feet is a pile of broken bones that the marrow has been sucked from. The gray head snaps up as the door opens, long dead eyes staring hungrily at the Goblin.

Initiative 16

Before the ghoul has time to react, it has been disarmed by the furious goblin, and beheaded by Xiao, who finishes it off by smashing it's chest with her fists.

Twiglet will follow Tallanvor into the room and take a shot with his bow as soon as the ghoul looks distracted and hide again with my bonus action

Initiative 11 

Short bow sneak attack Attack: 14 Damage: 11

Ro spins around, looking for anything else moving in the room. Finding nothing, she starts hacking at the South door with her swords.

The door is turned into splinters eventually. On the other side she finds herself back in the room where she fought the pesky blood hungry bats.

Once she's calmed down, Ro beckons Twiglet forward to scout ahead.

Stealth: 10

Perception: 21

After Ro calms down, Twiglet and her exchange a quick few signs and then approach the rest of the party. "We'll take a quiet look at those rooms behind the jelly...thing" Twiglet suggests. Twiglet recovers one of the lamps from the "bat room" and fashions a dark lantern using some of the cloth on the floor of the "ghoul" room, making it as low light as possible.

Straining his ears, eyes and sensitive feet, Twiglet heads off into the North-West mining works

Stealth 23

Perception 17

A still pool fills much of this cavern Twiglet discovers. The water is dark, revealing little of what might lie within. The shore of the pool consists of a thin layer of broken shells from strange, pale mussels, and a fishy odor hangs in the air. A shallow stream flows north&west out of the room along a tunnel. Craved steps leave the room to the east.

Continue around the edge of that cavern to the craved [sic] steps, if I don't have to go through the pool, and into the next room

Up the carved (yay typos) steps, you find yourself in another corridor. Ahead is a closed door through which you can hear deep rough voices arguing in a language Ro knows to be Goblin. To your left, the corridor going up another set of steps.

Ro translates for Twiglet.

After signing [trap, door, head], Twiglet quietly lays a trip-line rock-fall trap, securing the line from part of the door lock, via a wedged stick, to the door frame and stones piled above the door frame using the carefully wedged stick to retain them. If the door opens without first cutting the line, the stick will be pulled out and the rocks will fall on (hopefully) the head of the person pushing the door open. There are only small rocks around them and the small bits of wood to hand, used to make the wedged, won't support enough weight to make the stones do anything more than a give a shock and -maybe- a lump on the head....but it should slow them down.....briefly.

Slight of Hand check with thieves tools 11

Its a shoddy trap by anyone's standards, but the best he can do with what is available in the mine

After a few seconds Ro starts signing to Twiglet:

[They is complaining about not finding enough food in the cave, and guarding this door is boring. They is thinking the door is only having not-dead on this side. These voices is too deep to be goblins so they is probably bugbears. I think there is goblins and bugbears only on that side maybe.]

...

[Something about boss lady no being of their kin. I can no say if they is meaning the lady is no a bugbear or if she is no a goblin or both. Big Boss is telling these goblins she in charge of this cave and they is not happy about taking orders from her]

...

[They is angry about goblins and bugbears getting killed by not-dead when she is giving stupid orders.]

...

[Now they is saying one of them killed a dwarf and-

Ro's eyes narrow and she pauses for a moment before continuing

[They is taking the other dwarf to see boss lady somewhere deeper.]

Ro shifts her weight back and forth for a few seconds, unsure of what to do.

[I think we can no kill two bugbears with just you and me. I is made of rage but bugbears is made out of rage too. Two bugbears is a lot of rage.]

...

[We should check there is no more not-dead behind us and up those stairs maybe. Then we come back with friends and kill them all]

Tallanvor searches the room for anything useful and heads to join the small ones.

Perception: 18

Tallanvor finds nothing in the old Barracks room

Humblodt does the same, giving the craven steps a menacing look on the way.

Ro moves back down the stairs to stop anyone getting close enough for the bugbears to hear, and then asks Twiglet to relay what we found.

Humblodt's investigation of the pool room doesn't reveal much. The water in pool is very dark and still so that you can't see what may be below it. The tunnel cut by the stream looks to be around three feet high and the stream itself is about the same deep.
