The remaining lich doesn't have shield so I don't think you have to worry about that.

Count will continue his rampage against the lich:

Attack 1: 4 plus 18 Damage: 7 plus 12 devine smite

Attack 2: 3 plus 25 Damage: 10 plus 15 devine smite if against the eldritch lich

Haste Attack: 1 plus 23 Damage: 7 plus 9 devine smite if against the lich 

BA the sword attacks the lich as well:  2 plus 14 Damage: 9

 But it did use it in the quote above ^^

Dragon breath recharge 4

(Why are we attacking fleeing foes? Allowing them to re-engage without using a saving throw at the end of their turns seems unwise.)

Dolrik takes half 16 damage from the death dragon (potion of invulnerability).

Dolrik sees Nadir get stunned, but flown away. He’s frustrated that he has no “cure” for that.

He remounts horse and approaches Count. Horse will dash if necessary or Dodge if not. He dismounts.

Rawrer will keep up with movement (40’), movement with teleport (another 40’) if necessary and then distract.

Action: Sacred Flame the most wounded enemy within 60’ range.

DC 19 Dex Save or 8 radiant damage.

Bonus Action: Sacred Flame the most wounded enemy within 60’ range.

DC 19 Dex Save or 3 radiant damage.

Blessed Strike adds 2 more radiant should one of those cantrips causes damage.

End of turn 9:

HP D//R: 87/96+6 (or 14) thp // 6/22+14 thp.

Sanctuary (on Rawrer): 9/10

Bless: 9/10

Twilight Sanctuary: 8/10

Resistance to all damage: 4/10

Shoot. Forgot my concentration check to maintain Bless.

Vermithrax is going to start back in on the other dragon, he will fly back towards it, with hasted speed and try a fly by attack on it:

Attack 1: 1 plus 25 Damage: 21

Attack 2: 1 plus 24 Damage: 14

Attack 3: 4 plus 24 Damage: 11

Haste action disengage and fly off, BA dash if need be to stay out of dragons range

Dragon haste and invulnerability round 8

Count haste and invulnerability round 3

 Ignore the BA dash, I've been playing a Rouges too long!

Quote from NathanAscher >>

Yoku the Hunter has honed his Prey and uses Insightful Fighting as a bonus action to sneak attack the Lich for 1 minute, Insight 1+17+8 versus an opposed Deception check.

Yoku Attack vs lich, 1+8+10, damage 7+6+7
Yoku Extra Attack vs lich, 1+18+10, damage 5+1+7
Yoku Haste Attack vs lich, 1+17+10, damage 8+1+7
Add Colossus Slayer 8 damage
Add Sneak Attack if Insightful Fighting triggers 6+4 damage

The Lich should attempt a DC 26 Deception check to avoid the sneak attack damage,

Arrow 1 (with colossus and with sneak), 38
Arrow 2, 13
Arrow 3, 16

>>Failed. It uses It’s legendary resistance to succeed, and It casts Shield to block his first attack. It uses a legendary action to cast Acid Arrow on Yoku, hitting. 

Nice, so the Sneak Attack Damage is removed, and the first attack misses, colossus is only on a hit, so I get to move it to the second arrow
Arrow 1, miss
Arrow 2 (with colossus), 21
Arrow 3, 16

Yoku will take half of 9 damage from acid and attempt a concentration save for hunter's mark Constitution DC 10 vs 3+11+6

 Actually, as Nadir pointed out, this lich doesn’t have shield-I was getting the two lich’s mixed up. So your original damage is correct.

Yoku cheers Count's efforts, "Smite that son-of-a-lich!"

Yoku Attack vs lich, 3+2+10, damage 6+1+7
Yoku Extra Attack vs lich, 3+7+10, damage 4+6+7
Yoku Haste Attack vs lich, 4+20+10, damage 5+6+7
Add Colossus Slayer, 5 damage
Add Sneak Attack granted by Count, 5+3 damage

Ben targets the wight's with his last fireball bead, 38, if possible, he wants to hit both the Skeletal Commander and as many Wight's as possible, in that order, add a zombie or two if they are bunched together.

Yoku remaining HP 79/86 (10/14), remaining arrow 19/40, remaining spell slots (3/4), (2/2), remaining fey step 3/3, haste 2/10, invulnerability 7/10, insightful fighting 9/10
Ben remaining HP 86/86 (13/12), remaining spell slots (4/4), (2/2), remaining beginners luck 2/2, necklace of fireballs (0/4), absorption 20/20, invulnerability 2/10, mm 2nd (7/10)

Arrow 1, miss
Arrow 2, misses if shield is cast again
Arrow 3, critical hit, starts 5+6+7, total 18, plus 5 (colossus), plus 8 (sneak), grand total 32
Crit dice add 2d8 +3d6, 13

 Second one actually hits for 17 damage, plus another 45. Ouch. It’s now a lichkebab. 

Ben can get them all in the fireball radius, except for the one eight who wasn’t running.

Haste Attack: 3 plus 17 Damage: 10 plus 13 devine smite if against the lich 

BA the sword attacks the lich as well:  3 plus 19 Damage: 7

 The lich is down, so I don’t expect you’re smiting? If you go after the death dragon instead, those all hit.

 Yeah that’s cause I got the stat blocks mixed up.

 That’d be the one wight. It fails both, and isn’t looking good.

 They all hit! Awesome. It’s not quite bloodied yet. 

I don’t think Nadir has gone yet?

I don’t think Nadir has gone yet?

 Nadir failed the ST and is stunned this turn. She was riding Godric though and the griffin dashed to the Death Dragon:

Quote from cyreon >>

Nadir is stunned but Godric carries her posthaste to the Dragon.

(Did we dispatch our host? If so, what is the motivation of his remaining minions?)

I'm fine count smiting the dragon, just didn't want to use it on the smaller enemies of redirected.

Count is out of spell slots now though!

I think the illithilich will return I'm 10 days based on abilities otherwise why woukd it face us directly so I'm sure minions know that and want to win favor.

(Sorry guys, long couple of days. Give me a minute.)

 Correct. 

The death dragon uses all three legendary actions to attack Vermithrax, only hitting once. 

As it’s breath just recharged, it releases a wave of necrotic energy, catching everyone on your team in it. DC18 Dex save or 45 necrotic damage, half on success. (I’ll roll

The greater zombies and skeleton commander move and dash to return to melee range with the frontliners.

The one remaining wight lashes out at Godric , hitting with a 21 for  6 damage. You guys are up again!

Dex Saves D//R: 10 // 25

Concentration to maintain Bless: 10

Ouch, even with the temporary hit points, Rawrer is dead dead with 25 hp damage below his normal 22.

RIP buddy!

Dang it. Forgot about the potions of Invulnerability.

Recalculating …
