[Wild Magic Surge: 5]

 A modron appears in an unoccupied space within 5 feet of you, and starts attacking the Sahuagin!!!

ALL TO THE BARON!!!

18 if it hits, 3

6 if it hits, 3

9 if it hits, 8

14 if it hits, 7

Perci's attack misses, the fish monster sure is slippery!

Sy, you're up! What are you doing? You do see a mondron appear, flying above Kash. It seems to be helpful, as it attacks the Sahuagin Baron. 

"Well...that's odd..."

"That's a, uh, strange occurrence. You've got some odd magic at your disposal, Kash."

What is that? Can I take it apart? What powers it? What can it do? John asks from the floor.

"I have no idea what it is....or where it came from..."

“We have this, Captain.” The LT yells out. “Greywind, finish these bastards off!” 

She attacks the Baron with a spell, she just points a finger and he is covered in flames. 

Dex: 11

And he fails! Taking 17

Sarge comes rushing in and tried to tackle the creature:

4

But he ends up slipping on some slimy fish blood and slams into the railing behind Kora.

The Vexation crew holds as their Captain give them a command to do so. All eyes are on Greywind.

Johnathan, you’re up. What would you like to do?

John gets up as he rushes the Sahuagin Baron with his club (I think it’s within my speed. If not, say so please.) giant cube thing! Mind if I help you and then take you apart? He swings!

Attack: 18 Damage: 10

Success, as Johnathan’s swing connects with the side of the Baron’s skull. Staggering him, he’s looking mighty weak! 

Advantage on all attacks against him until his turn!

Kora you’re up, the battle is almost won...what do you do?

Kora

She stands up on the rocking deck, still grinning, glances at her new wound and pulls a hand axe off of her belt. There's still a Sahuagin in front of her (he of the bite miss but spear stab) so she will go for him, slicing low with her short sword, and following up high with the hand axe.

Action: Short sword: 6 to hit, for 4 piercing damage
Bonus action: Hand axe (off hand): 17 to hit, for 3 slashing damage

The Sahuagin falls down dead after her second strike. The first one piercing it’s groin, if that’s where it’s “located”, and the second slashing across its ugly fish monster mug. 

“Yes! Good job, Greywind! Almost done!” LT yells in excitement. Her pride at the unit coming together in battle and defeating foe and after foe could be heard in her voice. 

Isuzu, what would you like to do now?

Isuzu

Isuzu attempts to target the Sahuagin Baron with Chill Touch Attempt to Hit: 9 If Hit Damage: 8

Kashkaval

Kashkaval raises his left hand and points a finger at the Baron who tried to kill him a moment ago and unleashes a beam of intense cold energy

[Ray of frost: 15 Damage: 7  cold damage and their speed is reduced by 10]

The baron dodges Isuzu's attack, taking a half-step back.

But then he is hit square in his chest, right in the area that has been cut and slashed open. The beam of cold energy splashes against him, going to the heart of his wounds and freezing them over. He makes a gasp for air as he falls over holding his chest. The last Sahuagin Baron is dead!

Two (2) Sahuagin remain!

The three last remaining Sahuagin were ready to fight unto the bitter end, as long as their Baron was still standing. Seeing their Priestess and both Baron's dead they yell out and Disengage . Jumping off the deck of the ship and diving into the depths of the lake called Galifar, returning to the depths from whence they came!

COMBAT OVER, ENEMIES DEFEATED!!!!

Kashkaval leans heavily against the mast and breathes a sigh or relief, then looks around to make sure the rest of his party is ok.  He also looks quizzically at the modron floating above him.

"Good job, Greywind!" Lt. Winehand says over the cheers and shouts from the Vexation crew. 

No lives were lost, thanks to the heroic actions of everyone on board. Though, there are a lot of injuries. And the Vexation has sustained some damages, but all in all, Aundair's finest proved their mettle against a sneak attack of a powerful force. 

Sarge picks himself up off the deck, rubbing the egg that appeared on his forehead. The Captain of the ship has the men and women of the Vexation dump the bodies overboard after looting them, of course. 

"Greywind, excellent work. Our healers will see to your injuries. Thank you for protecting the Vexation and being an exemplary example of what it means to be an Aundairian soldier."

The modron floats there for some time. Looking around for enemies, seeing none he lands next to Kash. He speaks to Kash, "Ee-ooh beep ta-doop." 

Kora

Standing over her kill, she pokes it with a soggy boot, breathing heavily. Then she, too, looks around at her unit, noting they are all still standing. She is sopping wet, long white hair dripping in her face, plastered to her disheveled uniform, her chainmail shining beneath. She wipes her short sword and axe, to get most of the Sahuagin blood off, belts the axe and hooks the sword into her belt. She will clean it later.

Then she looks to the LT for instructions and if none are forthcoming, begins to help right the ship, assisting in carrying wounded, moving heavy things, greeting the soldiers on the ship with a nod and a "Well fought," or the like. She will keep an eye on the modron, but move along and not engage with it, letting Kash, Johnathon, or others handle it.

"Well, that was exhausting. I've got a bottle of wine in my quarters, who wants a glass?" Percival looks up at the floating modron. "So, how'd you summon that here? Not that I'm complaining, just curious."

The minotaur stares blankly at the modron, then shrugs, and pats it on the head.

"Um good job?!"
