Sahuagin 15: Claw Attack: 18 Damage: 2
Sahuagin 15:  Bite Attack: 18 Damage: 4

Heilamin, you're up!

Heilamin gives Brazzak a bardic inspiration (d8) and cast vicious mockery the closest Sahuagin. DC14 vs WIS Save: 7 it fails taking 4 damage.

Champion 2: Attack: 15 Damage: 10
Champion 2: Attack: 14 Damage: 10

First mate continue to attack Sahuagin 1
First mate: Attack: 13 Damage: 8

Modron, you're up! Followed by Mackenzie.

As Champion 2 moves  to engage Mackenzie in melee he takes the oppoornity presented to make a thrust of his halberd at the Sahuagin (Polearm Master reaction) before receiving the 3 attacks....

Attack: 27 Damage: 9

...and as this strike hits home Mackenzie will call on his divine connection to smite the creature (cast at 2nd level) for an additional 7 of radiant damage.

Will edit further action following Modron's turn as his action will determine Mackenzie's action....

Just btw...Mackenzie is looking pretty bloodied from the attacks he has been absorbing from the Sahuagin Champions.....

Mackenzie cleaves into Champion 2, making it heavily wounded. 

Modron will send another meteor to attack as many enemies as possible (sculpt spells evocation capability allows me to choose 4 friendly creatures who are not effected by the meteor blasts (successful save and no 1/2 damage on success)).

BONUS ACTION: Send another meteor into the battle for 7 fire damage to enemies within 5 feet of it.

Modron will then cast fire bolt at the nearest enemy creature.

ACTION: fire bolt Attack: 26 Damage: 29

Sahuagin 14 and 15 DEX save: 6 17

Sahuagin 15 is nimble on their feet and dodges most of the damage, taking 4 fire. Sahuagin 14 falls dead to the hit from the meteor. Your firebolt misses it's target. 

Mackenzie, your go at it. Brazzak is on deck. Brazzak reminder you have a bardic inspiration dice you can use on any attack or ability check from Heilamin. 

Posting Champion 1 since it's target is Captain Andy. 

They continue to press on Captain Andy, furious at it's misses from the first round of attacks. 

Champion 1: Attack: 10 Damage: 10
Champion 1: Attack: 18 Damage: 8
Champion 1: Attack: 6 Damage: 8

Captain Andy dodges two of the three attacks and tries to parry, but the spear lands and hits him on the shoulder.

As Meteors and FireBolts fly from the mage Mackenzie exclaims with a short but withering glance at Modron "We are on a wooden boat in the middle of the ocean!....." amazed that slinging fire around is seen as a good idea, then quickly assesses the Suhuagin in their immediate area and decides that using Conquering Presence would not be that effective and decides instead to risk attacking the Champion (2) yet again, seeking to take him out of the fight but also yells "Unless any of you know how to sail this ship we need to save the Captain....Renee - can you shoot his attacker?"

Attack: 9 Damage: 14

Attack: 13 Damage: 5 -> Mackenzie will use Guided Strike to make this roll 23 and will smite (2nd level spell slot) for an additional 12 damage to the hit

Bonus Action:  Spiritual Weapon attack Attack: 14 Damage: 6

If Champion 2 is still standing

 If Champion 2 goes down:

Mackenzie barely misses with their first strike (AC 16), and with the help of guiding bolt you burst forth radiant energy...killing Champion 2. The spiritual weapon appears next to Champion 2 but unfortunately misses. 

Brazzak, you're up.

The dragonborn swings heavily at the two enemies in front of him.

Brazzak swings twice on Sahuagin 15 and knocks them dead. Brazzak then moves standing next to Renee's ape and strikes down Sahuagin 7 who falls limps to the wooden deck. 

Champion 3 is furious at the death of it's comrade, and strikes at Mackenzie with a blood frenzy in it's eye. 

Champion 3: Attack: 16 Damage: 11
Champion 3: Attack: 19 Damage: 7
Champion 3: Attack: 21 Damage: 4

Sahuagin 2-5 all take the Dodge again on their turn and Sahuagin 1 presses on the first mate.

Sahuagin 1: Claw Attack: 6 Damage: 2
Sahuagin 1:  Bite Attack: 9 Damage: 2

The first mate is sliced by the first attack but is able to parry the second attack. 

Sahuagin on the upper deck are going to jump down in spaces adjacent to Heilamin and Renee, Sahuagin 6 and 8 attack Renee and 10 attacks Heilamin. Sahuagin 6, 8, and 10 take 2 fall damage from jumping down from the upper deck. Sahuagin 9 moves to the top of the stairs and strikes down at Brazzak. 

Sahuagin 6: Claw Attack: 14 Damage: 2
Sahuagin 6:  Bite Attack: 4 Damage: 5
Sahuagin 8: Claw Attack: 8 Damage: 5
Sahuagin 8:  Bite Attack: 5 Damage: 4

Sahuagin 10: Claw Attack: 17 Damage: 5
Sahuagin 10: Bite Attack: 12 Damage: 5

Round 3!

Captain Andy, damaged by the Champion in front of him can see the blood frenzy in it's eyes. He continues to fight on with one hand on the wheel, letting go now with the waves and speed is not an option. 

Captain Andy: Attack: 20 Damage: 5
Captain Andy: Attack: 22 Damage: 5

Round 2 Initiative order:
Captain Andy
Renee
Heilamin
First mate
Modron
Mackenzie
Sahuagin Champion 1
Brazzak
Sahuagin Champion 3
Sahuagin 1-5
Sahuagin 6-10

Renee, you're up followed by Heilamin!

Renee manages to avoid all the attacks aimed at her (ac 14). She attacks Sahuagin 6 with her rapier while as bonus the Ape will attack 9

Rapier: Attack: 8 Damage: 6

Ape: 

Fist attack one: Attack: 13 Damage: 4

Fist attack two: Attack: 19 Damage: 6

OOC: I don't think that Mackenzies actions will be impacted by or impact on initiative order so posting now.

"To the depths with you" Mackenzie murmurs as the first of the Champion's fall to his blade before feeling the sting of the other beasts attacks.  Spinning to face this one he takes one deep breath to refocus and brings one hand to his heart to quell the pain [Action to use Lay on Hands to heal 27 HP] so that he might stay in the fight to save the ship from being overrun. As he prepares to receive the follow up attack from the remaining Sahuagin he wills the Spiritual Battle Axe to move to the Sahuagin attacking the first mate yelling "Just keep it at bay Captain....help is coming"

Bonus Action:  Spiritual Weapon attack Sahuagin 1 (First Mate opponent at in Nth East corner) Attack: 7 Damage: 7

Quote from Jilguera >>

Renee manages to avoid all the attacks aimed at her (ac 14). She attacks Sahuagin 6 with her rapier while as bonus the Ape will attack 9

Rapier: Attack: 14 Damage: 8

Ape: 

Fist attack one: Attack: 8 Damage: 4

Fist attack two: Attack: 12 Damage: 9

OOC: Shouldn't you get to use sneak attack because Heilemann is based with Sahuagin 6 as well - I think you should be rolling the extra 4d6 damage for your attack if it hits.
