Sorry - here's the map and damage tracker: Map

The scavvers keep attacking her friends. Vesta winces as she sees one of the scavvers take another deep chomp out of Davis. She takes aim at that scavver and unleashes some more fiery fury! She draws deep from her innate magic and manages to duplicate the spell so that there are eight rays of fire, four for each scavver! (Metamagic - Twinned Spell)

3rd Level

Ray 1: Nat 1 :(

Ray 2: 30 to hit; 11 fire damage

Ray 3: 17 to hit; 11 fire damage (includes affinity)

Ray 4: 17 to hit; 8 fire damage

(Can Zyl get in a flanking position?)

Lyrena goes down!

(in 5e rules, Scorching Ray can't be twin spelled because it can target more than one opponent...and in 5.24 rules the spell has to be able to target additional creatures at higher levels. I'll take 2 rays for each scavver - 1 &2 on blue and 3&4 on red.)

(If Zyl moves to a flanking position, the scavver will get an AoO. She is by its head, and it has a 10' reach!)

(That's fine, Zyl thinks these nasty space monsters and suck brownies. :P)

Zyl moves to a flanking position in her rage and swings again!

Attack 1: 24 to hit, 15 fire (rerolled with Savage Attacker) + 4 fire (elemental cleaver) + 3 (rage bonus) = 22 damage total

Attack 2: 29 to hit, 11 fire + 6 fire (elemental cleaver) + 3 (rage bonus) = 20 damage total

AoO on Zyl - Attack: 16 Damage: 23

Round 2: 
Lyrena tolls the impending demise of the red scavver (DC17 Con save - 4)
Red Scavver is in a blood frenzy and snaps viciously at the only target around it - Lyrena! (Attack: 26 Damage: 34)
Blue Scavver is also in a blood frenzy and keeps trying to bite Davis. (Attack: 28 Damage: 42)
Zyllynne chops the big blue night scavver twice, nearly killing the creature.
Davis 
Vesta sends rays of fire at each big fish, finishing off the blue one and adding more damage to the red one that is chomping on Lyrena...
Vanizi 
Katarina??

 Oh, you're right. Darn! I'll remember that for next time.

Vanizi sees Lyrena succumb to her injuries. "Look! Can anyone get to Lyrena?"  She motions, calling out again to cast Eldritch Blast at the Red Scavver.
(Attack: 13, Damage: 11) 
(Attack: 21, Damage: 12) 
(Attack: 28, Damage: 11) 

She starts to move toward Lyrena, though she would try to allow others to move ahead of her to intercept the creature. 

Vanizi sends concentrated force blasts at the red scavver, hitting it twice and killing it. (Combat over! Lyrena is down and will need to make Death Saves unless someone stabilizes or heals her!)

Davis will go over to Lyrena heal her for 10 hps to get her on her feet. (Lay on Hands)

How close are we to the boat, and do we see other 'monsters' about? Trying to decide our next moves before I use up my healing slots! :)

Lyrena gets to her feet, brushing imaginary dust off her clothes. “Thank you,” she says stiffly. She hesitates for a moment before continuing, “I apologize. I know I haven’t been of any help so far. I only ask that you give me the benefit of the doubt; I can be of use.”

Zyl floats over and smiles at Lyrena, offering another brownie. "Is okay pretty lady! Here, have another brownie you'll feel better ok? Okay." She smiles and starts floating off whether Lyrena takes the brownie or not.

Vesta floats over to Lyrena. "Don't say that. We are glad to have you," she says. 

Watching Zyl hand out another brownie, the sorceress exclaims, "Zyl, do you have a Bag of Holding full of brownies? Where do you keep getting all of those?"

Vanizi slows as others rush to Lyrena's aid. "Ah good, she ok."

Zyl just shrugs and grins, reaching into her bodice for possibly another brownie. "I always stock up before I go out!" (her pack also presumably carries a fair number of brownies :) )

You can quickly reach the prow section of the Lambent Zenith since you were about halfway across when the scavvers attacked. If you weren't sure why the shipwrecked crew didn't just move from one section to another, you are definitely certain now!

A colossal heart—part flesh and part stone—looms over this segment’s top deck, a 15' x 30' deck that would have been the most forward on the ship. What remains of the ship’s prow is plunged deep into the heart, and the deck rumbles as the heart slowly pulses. Scraps of gossamer sails dangle off the ship’s broken-off mast, which is jammed through one of the doors leading into the forecastle. Another door is closed, but unblocked, and a central ladderway leads deeper into the prow section. (Map)

"Umm, should that heart thing be still going like that? Should we be worried?" Vanizi wonders aloud as they arrive at the front of the ship. "No signs of where we might find the rod piece here.  Should we try inside those doors?"
