Initiative Order:

Syvis
Goblins
Ceo
Petcan
Bow
Grim
Randall

(will roll for init. if/when the others post and fit them in if the fight is still going.)

(there are 8 goblins in the stables. Syvis is up.)

"They went into the stable!" Syvis calls out to others, seeing the goblins all scrambling into the stable and hiding behind the wagon, but others are already following them inside. Knowing that the element of surprise is lost, Syvis opts not to hide again and instead quickly drawing an arrow from his quiver and aiming at one of the goblins. 

Attack: 23 Damage: 5 

Syvis wounds one in the leg and it tries to limp behind the wagon and hide (stealth): 22 

Goblin 1 attacks Syvis: Attack: 6 Damage: 7 
Goblin 2 attacks Ceo: Attack: 5 Damage: 7 
Goblin 3 attacks Petcan: Attack: 17 Damage: 8 
Goblin 4 attacks Bow: Attack: 10 Damage: 4 

Goblins 5, 6, and 7 each let a horse out of their stalls and the 3 horses begin to neigh and try to move away but the goblins use them to duck under and run between their legs. But for medium sized or larger creatures it is difficult terrain.

(Ceo is up.)

(Goblin 8 was the wounded one trying to hide behind the wagon. It is dim light inside the stable so those without darkvision make their perception checks at disadvantage/ -5 for passive perception.)

Ekō swiftly moved back by the others. She was ready for anything 

Ceo starts playing on his pan flute an elvish lullaby.

Sleep Hit points affected: 15

Petcan moves up and stabs goblin3 with his daggers

Attack: 25 Damage: 7 

Attack: 15 Damage: 2 

Bow makes sure he is within 30ft and will shoot with his handbow as an action, and a second time as bonus action. He will target goblin 4, and if he dies after first hit, the second attack will be on goblin 2 (assuming sleep is cast on some of the hidden goblins)

Attack on goblin 4: 7 Damage: 6

Attack on goblin 4 if not dead yet, and otherwise goblin 2: 12 Damage: 10

(Eko's init: 14 )

Ceo plays a lullaby and 2 goblins fall asleep. Petcan kills a goblin and stabs the one fighting Bow. Bow shoots a couple of shots from his hand crossbow but misses.

Initiative order:
Syvis
Eko
Goblins
Ceo
Petcan
Bow
Grim
Randall

(Grim is up.)

Grim attacks the Goblin closest to him that isn't asleep or 8.

Grim Attack 17  Damage:  10

Randall:

Bringing up the end of the batting order, Randall finally makes it around the doorway into the dim combat zone.  Saying, "Morninglord shower his light on all your valorous endeavors!" he causes the head of his mace to illuminate with the warm yellow Light of a summer's morning and moves into melee next to the others, trying primarily to make sure any of those sneaky goblins don't get away to cause more mischief in the town.

Grim severely wounds a goblin and it promptly falls to the ground (prone), dropping it's weapon and holding up it's hands, and starts screaming, "Bree-YARK! Bree-YARK!"

Those within 20 feet of Randall are in bright light, beyond 20 feet, out to 40 feet is dim light.

The sudden bright light startles the horses and they begin to buck and kick. (Anyone getting close enough to make a melee attack against the goblins suffers 1d4 bludgeoning damage per attack they make. You can roll it yourself in your post if you choose to still attack. Once for each attack you make.)

(Syvis is up.)

Perception (looking for goblin 8): 7

Keeping his keen eyes at the scrambling goblin, Syvis catches sight of the wounded goblin ducking behind the wagon. He swiftly moves to an open area where he can get a clear shot and calls for his companions, "There's one behind the wagon." He readies his arrow on his taut bow and prepares for firing. 

Randall:

After having lit his mace then walked into the building, Randall is surprised when the horses react so severely, but he sees the advantage for them with the goblins running around underfoot below the panicked horses.

”The horses may do our work for us!” calls Randall, “We should back off and clean up whatever is left.”

Ekō throes a ice knife at an goblin 

if it hits 2

then it explodes 8 of ice damage

(Eko's attack: 11 )

Eko's Ice Knife misses it's target but then shatters in a burst of icicles and kills 3 goblins (1 of them being 1 of the sleeping ones).

(for this 2nd round the remaining 3 goblins will be referred to as 1, 2, and 3 but are not necessarily the same numbered goblins from the previous round)
Goblin 1 attacks Syvis: Attack: 22 Damage: 8 
Goblin 2 attacks Eko: Attack: 22 Damage: 4 
Goblin 3 attacks Ceo: Attack: 6 Damage: 5 

(Ceo is up.)

OOC:  How many horses are injured by the exploding ice dagger?  Do the panicked horses trample any of the goblins scurrying under their bodies and using them for cover?

Very good point. The cold damage isn't enough to kill any of the horses but an explosion of flying icicles does cause quite the commotion amongst them. One horse runs to the far end of the stables, another kicks out blindly at one of the goblins, and the last one trots over back into it's stall, whinnying as it does so.

Horse's Hooves' attack: Attack: 18 Damage: 8
