With Ben's killing blow, the hunter's mark is free to move to the cyclops.

 It fails the save! It’s starting to look bloodied.

 Nearly takes it down but not quite…

 One missile (3 damage) is enough to kill the hag. The other two redirect to the cyclops!

Nadir (@cyclops): 2 plus Attack: 21 Damage: 8

 Most of those hit! It’s not looking very good. 

The cyclops once again misses both swings at nadir. You guys are up!

Nadir tries to bring the Cyclops down with an array of coordinated attacks from woman and beasts:

Godric (@cyclops): Attack: 23 Damage: 9
Godric (@cyclops): Attack: 16 Damage: 9

Horse (@cyclops): Attack: 21 Damage: 9

Nadir (@cyclops): 1 plus Attack: 21 Damage: 10
Nadir (@cyclops): 4 plus Attack: 12 Damage: 13

temp HP Nadir: 9 or 9

I believe that should be enough and Nadir returns to formation with her companions. 

It is indeed enough! Dang, you guys are on a ROLL

8 and 3

This time, 30 ft away on the opposite wall, appears a four-armed troll, a frost giant skeleton, and a half-red dragon gladiator. The other three of you still have your turns! 12% chance 63

"If you wish, get behind me," says Nadir to her companions while preparing her defensive stance. (I think she can handle best the giant - with bludgeoning vulnerability - and the gladiator - that is medium size where she can get advantage.)

Count will send the dancing sword towards the troll and attack with it:

Attack: 3 plus 11 Damage: 5

Then will cast Fire Bolt

Attack: 2 plus 26 Damage: 16

Temp hp 10 or 9

Dolrik sees the troll hurt by fire and castsToll the Dead at it.

DC 16 Wis Save or 7 necrotic damage.

Rawrer distracts.

Round 4: 4/10 Bless | 3/10 Twilight Sanctuary

Yoku sees the others focusing on the Troll, so he uses his bonus action to move hunter's mark

Yoku atk1 vs troll, 4+3+10, damage 2+2+7
Yoku atk2 vs troll, 3+15+10, damage 2+2+7
Colossus slayer on first hit 2
Count grants 5 foot Sneak damage 1

Ben casts magic missile 1/3, on the troll 10

Yoku temps 11/11, arrows 32/40
Ben temps 12/11, scrolls 5/5

Count is still 30' away from the troll, the dancing sword has a 30' reach and he didn't get any closer yet.

Question is, does the Dancing Sword count as an ally for sneak attack? It is a tiny construct, I suppose.

 Those both hit! Nice Firebolt.

 That’s…55 damage between the two of you. Wow.

It kills it.

Heavens sakes. 

The skeleton targets Nadir (since she’s closest) with its Freezing Stare. The skeleton targets one creature it can see within 60 feet of it. The target must succeed on a DC 13 Constitution saving throw or take 35 cold damage and be paralyzeduntil the end of its next turn.

The gladiator moves forwards and targets Count, Spitz, and Yoku with Fire Breath . The half-red dragon exhales fire in a 15-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw, taking 28 fire damage on a failed save, or half as much damage on a successful one.

The skeleton doesn't come close?
