The arena: Monster killers.

So that could have been Ben's to cast/trigger...

Im

assuming you guys had done your best to spread out after it’s AoE, so I’ll allow it to just hit Ben and the Modron.

(Way I see it your best chance is to summon another modron and hope it’s friendly)

Anyway, Yoku?

 sorry was traveling, posting now

 No worries)

Bonus to move Hunter's Mark to the ancient construct and release two arrows

Yoku attack 1: 3+6+10, damage 4+4+7
Yoku attack 2: 1+19+10, damage 6+3+7

Add (+1d8) 8 on the first attack that hits

Ben casts magic missile from his only slot at the A.C., 10

HP Y//B: 60/60 // 42/42, arrows 24/40

Wild Magic Surge: DC 5 vs 55 

 Everything hits! That kills the construct. Ben’s  damage plus the 9 necrotic goes to the modron. 

The Modron tosses Rawrer’s body aside, and Nadir narrowly blocks a grasping arm. It manages to grab her with a second, dealing 8 damage and grappling her, lifts her off her horse and moves to Dolrik, narrowly missing him with another arm. It activates the Pillar of Truth on Yoku: dc15 Dex save, 25 force damage or half on success.

Ouch, Yoku took half of a fireball and half of pillar of truth, so he's starting to feel the pain. Does it look like the entire team is on-board to fight this guy? (He's pretty high in level and although we don't know his programing, he seems kind of angry)

Missed TS, retcon Yoku will add back lost hp from temps 8

And Ben's temps 10 from before taking the 9 necrotic damage (actually Yoku was injured so he will heal from the 18 damage)

My bad, I wasn't tracking hp so well and I just realized we are fighting a Challenge Rating 10 creature with three attacks, so I have to audit my hp,
Yoku had 50+10, took 13 damage from fireball, gained 8 temps from twilight sanctuary, healed 18 from wild magic surge necrotic burst, then took 11 damage from pillar of truth.
Ben had 38+5, took 13 damage from fireball, gained 10 temps from twilight sanctuary, took 9 damage from wild magic surge necrotic burst,

Yoku rallies the party, "I have the enemy in my sights, let's give it all we've got!" Bonus action to move Hunter's Mark to the Nanaton Modron,

Yoku attack 1: 2+7+10, damage 4+2+7
Yoku attack 2: 1+5+10, damage 3+6+7
Add (+1d8) 3 on the first attack that hits

Ben casts magic missile from his second scroll, 13

HP Y//B: 57+(0/11)/60 // 30+(1/6/42, arrows 20/40, Ben's Scrolls 3/5

 (Ha sorry but you don’t have much of a choice)

(if you were all fully rested I wouldn’t have any worries -I’ve been in a lvl 3 party that narrowly managed to beat a cr10 threat, but given your current state it’s gonna be super close)

Count will retrieve the sword from the air and Spitz will dash to Rawrer, passing within 10' of the Nanaton Modron. While within the 10 feet Count will activate his Channel divinity Vow of Enmity (As a bonus action, you can choose a creature you can see within 10 ft. of you and gain advantage on attack rolls against it for 1 minute or until it drops to 0 HP or falls unconscious) and when reaching Rawrer will give 1hp from lay on hands Ability and ride off away from the Nanaton Modron (100' for Spitz when dashing. How far can I get from this thing and give Rawrer 1hp After passing within 10' of it?) "Take the bolster from your master and run boy! You too Ben, get out of there!"

I will assume too far for temp hp.

Wild surge: DC 3? 18

(70 ft)

I only registered 8 damage to Nadir, that is correct? Also I believe the pillar only hit Yoku if we spread out? That means Nadir gets her bonus attack as the construct damaged someone else.

2 plus Attack: 30 Damage: 11
4 plus Attack: 28 Damage: 13
Bonus 1 plus Attack: 18 Damage: 14

temp HP: 2 or 9

 Awesome! That’s 48 damage between the both of you.

 Good deal.

 Correct. 

All three hit! That’s 39 damage from Nadir as well. Awesome! The Modron isn’t looking too well. 

The mofeln attempts to squeeze Dian in Nadir but somehow gets a nat one even with advantage. It moves to You this time as he’s the one that caused the most damage and grabs him, hitting with a 24 fir 9 damage and grappling him. It then grabs Nadir with another arm, hitting with a 27 for 14 damage. It then activates the Pillar of Truth on Dolrik: dc15 dex save or 26 damage, half on a success. You guts are up! Wild magic trigger should be a 6?

Rawrer is crushed beyond healing.

Sadly.
