Lost Lab of Kwalish

Both of Ana's attacks land, as do each of Gravity's.  Sam manages to hit once.

The huge lizard on the ceiling advances into the dark cavern climbing out over the water before releasing the slippery rock lining rhe tunnel and plinking into the water below.  A moment later, electricity crackles across the water's surface and explodes in a sphere of lightning, Encompassing Sam, Ana and Tetrevess. 15 DC15 Con save for half 

The smaller lizards scurry towards their mother. A few burst into little balls of lightning again.

The fastest (4) follows Ana along the west bank. Behind it, (2) pauses at the water's edge and blasts Sam and Tetrevess.  Three more swim out into the water, the furthest east (6) blasts Tetrevess.

Ana grit her teeth at the shock and impulsively pointed her finger at the big lizard and spoke the words of a rebuke. Flames sprung up around it for an instant. But she was not done and fired two more arrows at it.

(hellish rebuke at the big lizard as a reaction - Dex save DC 19 or take 33 fire damage.

Attack: 13 Damage: 9 )

(TETREVESS is standing in water that is more than ankle deep.  Lizards swim here, not standing upright as a human, but the water does become deeper as you move down on the map (tecnically North). To make things easier, I'm calling water "water" and anything blue is extra movement (difficult terrain) but because o failed to state this, Tetrevess can move out of the water (thus turn only) if desired, without the movement penalty.

(Post coming in the am!)

Constitution Saving Throw x Lightning Attack: 19

Tetrrevess save 12 

he casts absorb elements to take half the damage. 

on his turn, he uses fireball  (4th level) hitting the big lizard and any little ones he can without hitting our group.  
30. Fire damage-  dex  DC 19 for half

Just realized I didn't post  a capture if the battlefield. Whoops.  I think you were told the calf is further back in the cave.  He's on the Mao, but I notice he's still in a darkened area, so you wouldn't have seen him.  He's there though.

@Tesservett,  wait. Is it a fire damage fireball? The lizard is underwater and standing right beside you.  You can use movement to get far away before hand, but the lizard being underwater will shield it from fire damage. I think it's resistance iirc.

PHB 198 says...

Creatures and objects that are fully immersed in water have resistance to fire damage.

The little ones are swimming, they're like 90% underwater, so RAW, no resistance, and I think that's how I should rule it - no resistance for swimming lizards, just the one that fell from the ceiling and used no swim movement.

Actually makes me wonder if she can crawl around on the bottom, but I stead if swim speed use half movement speed. Probably not.

Is it visible then? Would Ana be able to target it?

Oh I’m sorry i didn’t realize one was fully underwater.  If that’s the case he’d use acid instead- (with his order of scribes feature)  and hustle out of the water!

 It's water with plenty of silt I suppose since the silt deposits are what line the sides of the water, but it was not my intent that it would obscure your vision.

The three small lizards (they're like 2 ft long, similar to your average green iguana) begin to thrash about un the water as it turns ro acid around them.  They soon sink below the surface, their bones rapidly stripped clean soon fall to the submerged muddy floor of the tunnel.

The large lizard, flesh seared by hellish fire and acid bursts from the water before Ana, biting and at her and whipping its tail and clawing at the warlock.

Tail  12 for 13 and DC15 Str of knocked prone

Claw  19 for 13

Bite 12 for 17 piercing plus 15 lightning 

The lizards continue to Harry the party. #4 bites Ana 6 for 5 piercing plus 2 lightning.

One of its siblings nips at Samogri's tail 15 for 6, as another tries to take a chunk out of Gravity 21 for 4.

Ana will use Misty Escape as a  reaction to teleport 30 feet north and turn invisible. She will then move 30 feet more away from the big lizard and shoot it twice, first attack with advantage due to invisibility.
