The Valley of Ends

Gotch peeks around the edge of the door, the glow from the two skeletons lighting up his targets nicely to his way of thinking. He looks over them for a moment, as his hand tugs another crossbow bolt from the case at his side. Fitting the bolt into place, he lifts the crossbow and takes aim at a junction of the armor one of the skeletons is wearing. Centering his mind he sends the bolt on it's way, pulling the trigger on his crossbow. Even as the bolt flies free, Ghotch is already turning away, moving out of sight of the skeleton's glowing red eyes.

Attack: 17 Damage: 11

Hide: 17

Resfaen laughs in the face of the skeleton at its useless attacks and then continues swinging her battleaxe at the skeleton.

Battleaxe #1: Attack: 23 Damage: 12

Battleaxe #2: Attack: 19 Damage: 10

note, due to Faerie Fire, attack against the skeletons are with advantage. 

Salys will move into the door frame and fire two quick shots at the skeletons, then (if possible) he will order Bearskr to charge through quickly to get to the other side of them.

Action:
Attack: 12 Damage: 14
Attack: 22 Damage: 14

Bonus action, order Bearskr to disengage and move 40 feet into the room, behind cover if possible.

Getting behind them is not possible due to the shelves taking up most of the room's space and the skeleton with Resfaen and Onyx occupy the middle walkway. 

Quote from Shodai_Kishi >>

Getting behind them is not possible due to the shelves taking up most of the room's space and the skeleton with Resfaen and Onyx corrupt the middle walkway. 

 Pulling back 15 feet into the hallway then.

I‘ll draw another scimitar and slash the marked skelleton into tiny little pieces.

Attack: 20 Damage: 9

Attack: 26 Damage: 5 (BA)

I assume it is dust by now, so my extra attack tries to hit the last one.

Attack: 16 Damage: 9

Fingoilin pops his head through the door again to shout at one of the 'undamaged' skeletons: "What did the skeleton order at the bar? A beer and a mop!"

Vicious Mockery - 5 - WIS 15

Then he back away into the hallway.

Salys rides into the room for a moment to unleash two loud gunshots into skeleton #2 while looking if he could get around but finds the room is mostly occupied so ducks back into the hallway. 
Start of Round 2
Onyx scimiat atrikes thrice with his scimitar but finds the skeleton #3 remaining at the end of the three blows that struck.
Resfaen strikes #2 with her battleaxes swiftly and heavy but the skeleton withstands the blows. 

Fingolin hurls inssults at the skeleton #3 and the magic seems to cause it to sutter for a moment as the magic takes effect. 
Save: 16
Gotch peeks into the room and fires another bolts into skeleton #2 before ducking back out of the sight. Unseen by the goblin but the rest, the arrow bounces harmlessly off the plate armor. 

Skeleton mindless strikes once more with their greatswords.

((did you account for Resfaen's battleaxe attacks? It was Fingolin with who used Vicious Mockery))

Damage was caculated, somehow just deleted Resfaen's attack while typing. 

Onyx will cast shield against the last attack sheath the second scimitar, move/cast his huntersmark and strike twice. 

Con save for first hit, if huntersmark stays up. 16

Attack 1: 27 for 13 damage

Attack 2: 15 for 11 damage

Gotch pulls another bolt from his case and fits it to his crossbow. Peering back into the room, his bald goblin head unnoticed by those inside, he takes in the scene for a moment. Then he lifts his crossbow and takes another shot at one of the skeletons.

Attack: 25 Damage: 11

(Due to Skulker feat, missed shot does not reveal location, so Gotch remains hidden, no action needed.)

Resfaen growls at the skeleton, "How dare you try to attack me, go back to the nine hell's from where you were spawned!" Then she will continue to attack the skeleton in front of her.

Battleaxe #1: Attack: 11 Damage: 10

Battleaxe #2: Attack: 26 Damage: 6

Fingolin shouts again from the doorway: "Who won the skeleton beauty contest? No body!", then he goes back into the hallway.

Vicious Mockery DEX 15 - 8

Salys will repeat as before, move up fire and retreat, ordering Bearskr to keep an eye out for anything coming to investigate the noise.

Attack: 17 Damage: 6
Attack: 15 Damage: 15

Bearskr perception: 22

Salys is a quick peek followed by two gunshots the first shot blows the head of the skeleton #2 near Onyx.
Start of Round 3
Onyx moves his hunter's mark around to a new target before striking. His first blow is a miss but his follow up is a hit but the skeleton seems ready to strike.
Resfaen strikes as well but her first strike misses but second strike cleaves the armor and skeleton within in half. 

After a few moments, there is no more sounds of enemies beside the party's nervous looks around the place. They relax as nothing else seem to springing out to strike at them. 

You're out of Initiative. Resfaen and Onyx are within the room. Most of he part is outside the room.

Fingolin goes to the door again, his next insult ready: "Oh... it's done! Good, is anyone hurt?"

He goes in and looks around the room to take stock of what's inside. Perception: 22

Onyx looks at the small wet spot on his shoulder. 

"You see, that's why i prever distance between me and my pray" 

He bends down and absentmindly picks up a pinky bone. 

The shelves are lined with all manner of items from bags, ropes, oil, tools but like the weapons, they're old, ragged and unusable. Fingolin looks into the collapsed shelves and actually see a leather tool bag moving slightly, even seen a glint of sharp teeth near the opening of the bag.

Onyx gains one skeleton pinky bone.
