((OOC: scrap this post… Lia can’t see the swarm… I’ll post something else below!…))

((Sorry grwo, was trying to be quick! The school is not visible to Lia just yet. She sees Stena, the fish thing, and Neth in the water, but that's it.))

Lia comes up on deck and sees Stena being bothered by some kind of fish. The others are calling for help and attacking it. With a slight sigh, she pulls out her shortbow and fires towards the fish creature!…

Attack action (shortbow): Attack: 18 Damage: 7 (piercing damage).

((Edit: the roller is being weird!! Original attack roll was only 8 to hit)) 

Stena yells angrily at Lia,

"Stop it, ye could have hit meh or meh friend here."

If she has time (or just for flavour) Lia would be gesticulating and calling back something like, “Come back!!… Get out of the water!…”. But much of that might be lost in the chaos, or misinterpreted, or not heard… what with the splashing!

There is some splashing and thrashing of tentacles in front of Stena's best buddy.

Stena, you are the only one with a clear view of the creature that suddenly appears in the water next to you.

 "Ewww, gross!"

A half dozen ray shaped forms dart out from under the boat where they'd been hiding, and make for Stena, surrounding her and her best buddy in a half circle on the boat side. The splashy thing that seems to be objected to by her buddy is between the buddy and the rock, within 5 ft of both her and her buddy, but isn't blocking her from the rock.

Stena's buddy snaps at the tentacle thing.

Stena's Best Buddy: 11 (-4)
Neth: 10 <----<<<

Buppido: 5 <----<<<

 Stena does the only sensible thing and stabs the freaky thing her best buddy attacked!

"What in Moradin's oiled beard is that?"

 Attack: 18 Damage: 7

((Disadvantage in the water))

She'd also paddle over to the rock, much better to have solid footing.

Neth realizes what happens and screams out to Stena “Don’t attack the squid you fool, it’s mine!”  

Neth launches a blast of energy and the big unfriendliest friend of Stena’s.

Eldritch Blast 

A 12 D 11

”Take that thing out and maybe she will snap out of it!” He yells to the others.

"Just stop! Aye'm warning ye! Yer squid thing just jumped us!"

Stena calls back.

((Sorry for leaving things in the lurch, I had every intention of keeping up on things, but I turn around and it's a week later... T'was a good trip though!)) 

Neth takes a crack at Stena's buddy, but the blast crackles wide, much to her relief.

Jimjar follows the tiefling's suggestion, and sends a bolt from his hand crossbow flying after the magic blast. 

Attack: 20 Damage: 4

Stena jabs the tentacled creature, which vanishes in a cloud of inky cold darkness.

Buppido begins winching up the anchor.

Neth: 10 
Jimjar: 10 
Stena: 8 
Buppido: 5

Something goes awry with Jimjar's attempt, and he curses in a few different languages as he tries to get it working again.

Galingal watches the situation in the water for a moment then shouts down at Neth.

"Grab pole. Get out water," Galingal says. He'll help Neth climb up into the boat if that's what Neth does.

Then he feels more than sees what Buppido is doing.

"Don't let boat go there," he says, pointing at the rock Stena has climbed on to. "More rocks under water. Rip up boat."

Lia tries to make sense of the scene around her. She plants her feet and tries to account for the swaying of the boat, to get into the sway and rhythm with her dancer’s legs…

She nocks another arrow and fires again towards the creature nearest to Stena, calling, “Stena, snap out of it, please! Get out of the water!!…”.

Attack action (shortbow): Attack: 7 Damage: 8 (piercing damage).

((Not sure if Stena did get onto the rock?))

((I believe she was 25 ft from it, used her action to stab the tentacle thing, and without a swim speed, is able to move 15 ft towards it, so is currently 10 ft away? And now 45 ft from the boat?))

Galingal extends a hand to Neth (no check required for Neth to get back onboard as a result, he'll be able to use his movement to get out).

Lia sends a bolt splashing into the water near Stena and her buddies.

The swarm of fishy things circles around to the far side of Stena, getting between her and the stalagmite that juts from the water.

Two of them, getting impatient, dart in at Stena.

Bite Attack: 11 Damage: 4
Bite Attack: 17 Damage: 2

It was then that Stena realized she'd made a huge mistake.

"Knock it off! Haha, those two... such jokers. No harm, right buddy? C'mon, let's dive down to the bottom, I think I saw a necklace that would look great on you!" Her former best buddy pleads with her.

Persuasion: 5

Stena treads water as she sees some if her blood float up in the water from a shallow wound on her arm. She looks to her arm, then to her best friend then to the other manta ray things and then back to her best friend, face slowly twisting from confusion to comprehension to fury.

"Why... why ye filthy, lying abomination-"

She clenches her jaw then disengages and climbs onto the stalagmite.

((Any checks to do that?))

She then yells to the others,

"Stop mucking about and kill these things! Especially that one."

She points at former bestest best friend.

((You'd likely take multiple opportunity attacks unless you take measures not to, and I'd like an Athletics to scramble up, but not as an action.))

((She disengaged,  meaning she should be able to just climb up without the AoOs?))
