The BFOAGWGH

I think there are 3 patches of ball bearings so going to see if enemies make it through them. (All Dex checks)

You heard two loud thuds as if large bodies have hit the ground, but the footsteps of the goblins gets ever closer.

Twiglet tosses his oil flask down to the team on the lower level, finds somewhere with some cover and readies an arrow

initiative 7

sneak attack (assumed to be from hidden) Attack: 23 Damage: 11

Bonus action to hide again

Ro hands all four of her daggers to Nundro and takes the oil flask from Twiglet. She pours out the oil across half of the north hallway entrance.

She finds a hiding spot close to the oil slick and lights a torch, holding it as far from the opening as possible so the cavern is lit but hopefully her position isn't apparent to anyone in the hallway.

Stealth (with disadvantage because even though she's around the corner she is holding a torch): 12

She holds her action - as soon as somebody reaches either the square where she poured oil or the square on the other side she'll drop the torch in the oil and step out to stand in front of it, blocking whoever is [hopefully] on fire from moving forward out of the fire.

Initiative: 12

Tallanvor helps the others up the rope. Once they are up there he hands Twiglet his crossbow. 

"Ye look like ye know what t' do with one o' these, boy." He passes over the bolts as well. "P'haps the drawves can use that shortbow o' yers"

He climbs back down the rope and casts light on a nearby boulder illuminating the entrance to the clearing so the archers will have a good shot during the oncoming battle.

"Aim true, may the light guide ye"

The first bugbear runs along the floor covered in the oil carrying a club in its hand and 2 javelins on it's back.. It doesn't see Roars hiding around the corner, who throws her torch at the oil puddle setting it on fire burning the bugbear. It screams in pain and continues onwards trying to extinguish the flames that cover it's legs. An arrow from Twiglet embeds itself in the bugbear's side.

Bugbear initiative 3 

Gundren initiative 3

Nundro initiative 14 

It swings it's club at Roars Attack: 24 Damage: 13 (It keeps changing everytime I edit the post so fixed the values)

Tallanvor Initiative: 4

((Humblodt's initiative: 11))

Humblodt steps up behind the bugbear and, casting shillelagh on his staff, he thwacks it against the creature's skull (19), dealing 5 magical bludgeoning damage.

Twiglet swaps his short bow for Tallanvor’s crossbow. It’s different to those he is used to, being from distant parts, but he is used to handling whatever kit is needed for a job. He drops the short bow near the dwarves with a fistful of arrows. 

Then, he sights down the crossbow

for next round, in case I am offline

Initiative: 20

Crossbow back-stab: Attack: 24 Damage: 11

Tallanvor will rush to the front to heal Ro on his turn casting cure wounds. HP restored: 7

(Plus 3 because Disciple of Life so Ro gets 13 total)

 The hit from the club almost knocks Ro off her feet but she grabs the cave wall with her free hand and recovers. She draws her second sword and roars at the bugbear - the hoarse wheeze made completely inaudible as she clangs her swords together. In the orange glow of the oil fire her face is a horrifying mask of oily soot, blood, and jagged teeth.

Somewhere way down in the back of her brain a little voice is saying "it a good thing Small Fear can no see this" but her roar is as loud in her mind as it was quiet on the outside. It booms and echoes off the inside of her skull, drowning out everything else.

If the bugbear is still alive Ro will slash upward at it.
Reckless Attack: 11 Damage: 8 (+2 for FURY OF THE SMALL)

If the bugbear is down and Ro can see another one in the tunnel behind it she'll throw a dagger.
Attack: 25 Damage: 8

If the bugbear is down and Ro can't see any enemies approaching she'll roar at the corpse again and claw at her chest in frustration.

Nundro attacks with the sling Attack: 16 Damage: 1

Gundren attacks with the short bow Attack: 7 Damage: 5

Nundro's pebble bounces off the furious bugbear while Gundren's arrow misses it's mark.

Humblodt's staff comes down on the bugbear's head with a crack and it falls limp.

Another bugbear and hobgoblin are running down the corridor. They dodge around the fire. Tallanvor heals Roars for 13 HP.

Twiglet's arrow bounces off the hobgoblin's shield.

XiaoLong swings the spider staff at the Hobgoblin Attack: 16 Damage: 10

Unarmed strike Attack: 15 Damage: 4

But her attacks do not pass through it's chainmail armour.

Roars slips through the hobgoblin's defenses and slices at it's thighs opening them up.

Twiglet aims for the armpit of the Bugbear when it swings its club

Attack: 6 Damage: 12

Hobgoblin attacks Roars with longsword Attack: 18 Damage: 8

Bugbear attacks Humblodt with club Attack: 6 Damage: 16

Twiglet shoots at the bugbear as it prepares to swing striking it in the armpit causing it to miss Humblodt. Blood drips the wound as it tears the arrow out.

The final bugbear comes up behind the other two. The fire burns out, but the bugbear is trapped behind it's comrades and cannot reach the party.

Nundro aims at Bugbear B with the sling Attack: 6 Damage: 1

Gundren aims at the bugbear B with shortbow Attack: 19 Damage: 4

Both attacks miss their targets.

Through the cacophony in her mind Ro barely feels the impact as it only does 4 damage.

MY RAGE BIGGER THAN YOU. I WEAR IT LIKE SHIELD AND SWING IT LIKE SWORD.

Undeterred, she continues hacking away at the hobgoblin.

1st Attack: 9 Damage: 6

Offhand Attack: 6 Damage: 6

The Hobgoblin deflects the blows effortlessly

XiaoLong attacks Bugbear B with her staff Attack: 16 Damage: 11

And then follows up with an unarmed strike Attack: 6 Damage: 6

The bugbear collapses under her assault.

Im out later, so for the next round I would do the same thing, Aiming for the Hobgoblin (fingers crossed)

Attack: 18 Damage: Unable to parse dice roll.

His bolt strikes the hobgoblin, but doesn't pierce its armour
