Road to Phandalin

 Skeleton  2 and 3 get up first after they get rattled by the thunderwave. They march forward and they attack the first living being they see:Dain.

skeleton 2 Attack: 17 Damage: 8
skeleton 3 Attack: 12 Damage: 3

Margret and Otrov still got their turns this round, so do skeletons 4 till 8.

Otrov can’t see much other than Dain so she will take the piton, infused with Margrets light, and toss it into the room to illuminate the immediate area. 

Then she will attack skeleton 2 attacking Dain, her eyes expertly finding the angles and space needed for a clear path.
 
Attack: 17 Damage: 5 and 10 sneak attack damage. 

I‘ll allow it but not aimed at anything.

The remaining skeletons move up against the door once more and number 4 and 5 attack Dain:

Skeleton 4 Attack: 7 Damage: 7

Skeleton 5 Attack: 13 Damage: 3

After Margret posts her action, round 3 will start.

Margret sheaths Talon then bonus actions her bow  

Attack: 18 Damage: 7

"Why are the mages going first damit!?"

She then action surges

Attack: 12 Damage: 6

Dain casts shield to deflect the attacks.

Margret, the first attack misses and the second hits, you shoot a hole into the skull of skeleton 4, but it is still standing.

Round 3:

Otrov answers Margret, “Because they’re a-mage-ing of course!” Then she lines up skeleton 4 and fires again. 
Attack: 11 Damage: 8. Plus sneak 9 

(I assume Nobody heard nothing with his last perception check last round, so proceeding under that assumption we're still okay.)

Nobody breathes a sigh of relief having heard or seen any worrisome creatures approaching the group. Realizing Dain may yet throw out again to defeat whatever it was the others tangled with instead of falling back to limit them, the tiefling dug deep, hisses out a word in draconic, and then with a mouth suddenly bulging, made his way south. As soon as he had eyes on the undead, he spits out takes a vile, black wad of some dark substances at them attention as much as it was on reflex, before retreating back northward.

Action: Ready the Acidic Spit for once an enemy is in sight.

 Movement: 15ft South, releasing the spell, then north again 10ft.

"It seems, we're at a dwarven impass Nobody"

She draws her bow again Attack: 22 Damage: 8

“Ye want in here, then have at it...” Dain says with a glance over his shoulder.  He disengages and move sout of the way of the door.

It looks like Nobodys strange blob did more damage then Otrovs and Margrets attack, but never the less, two more Skeletons crumble.

Dain switches position with Margret before the undead can react. The still standing skeletons fill up the ranks of the fallen and attack Margret:

skeleton 3Attack: 7 Damage: 3
skeleton 6 Attack: 9 Damage: 5
skeleton 7 Attack: 22 Damage: 13

 Round 4:

Attack: 14 Damage: 11

Fighting style works with versatile weapons.  Rerolling twos 5

Margret says "Ok" and as she does she tucks her bow away and bonus actions Talon blocks the incoming blow  and swings Talon

14 damage

Otrov notices Dain moving south and Margret taking his spot on the front line.  She doesn't want to get caught in the shuffle, so she moves to where Margret previously was: the alcove of the other door.

Whispering thanks to Tymora and congratulating herself for how smart she was putting all those hours into sharpshooting practice, she lines another skeleton up (if there is one available), gauging the sightlines and angles just so - both to miss the Paladin and to find an opening on the moldering undead in the room opposite.

Attack: 21 Damage: 4 and sneak attack 8

*if there is no skeleton visible just yet, Otrov readies her action until she sees one (using the above attack).

Nobody, who had all but brushed off the joke mages being 'a-mag-ing', kind of pauses mid-mixing of another acid loogey to give Margret a 'Not you too..' sort of look. Thinking about it later, he might laugh about it. But for now, he kept swishing the liquid about until the familiar sting let him know the time was right. At which point he ducked into the intersection once more, spat out another black blob of exploding acid, and then ducked back again northward.

Action: Ready the Acidic Spit for once an enemy is in sight.

 Movement: 15ft South, releasing the spell, then north again 10ft.

15

Margret shatters the undead in front of her and Otrov also shoots a head of the torso, wich leaves the body to crumble. Unfortunately Nobodys acid blob only hits the wall, while the last two remaining undead attack Margret:

Attack: 22 Damage: 7

Attack: 7 Damage: 4

after Dains turn, round 4 starts.

Dain sends a blast of blue power at one of the remaining skeletons...

ray of frost

To hit: 17
Damage: 4

That misses. 

Round 4:

Margret hums alittle Attack: 18 Damage: 12

and a worm of fire jumps out of the skeleton doing one point to the next one

Otrov lines another bolt up at the one she can see attacking Margret. She’ll kiss The Prick (with a little tongue for good luck) and fires:  

Attack: 21 Damage: 9  And sneaky 6
