BP2 Dex save -4

Baik targets the remaining pudding (PB1 was killed) with his Sacred Flame and the pudding is bathed in a brief bit of holy power. 

At the top of the round a third pudding climbs out of the acidic pool right behind Xavier, and attacks Xavier with its Pseudopod Attack: 10 Damage: 5 bludgeoning damage + 17 acid damage. Evidently it's climb was strenuous as the pseudopod misses Xavier's back. 

Eiren is up 

Eiren lashes out with another skeletal hand, targeting the pudding everyone has been attacking...

Deathly touch attack: 27 Damage: 5 necrotic

(Elven Accuracy: 10)

Velmine turns back to Baik and replies while she's still standing close to the black gate. "Not doing any good? Well, I know that, but how is this any worse than trying to kill those slimes that keep destroying my weapons? By the way, there's one of those gates around the corner here. A black one, which means we can use it to teleport around this place if I'm not mistaken. So there, at least I discovered something."

Eiren's chill touch leaves a deathly hand, somehow gripping the ooze. 

The second Pudding moves to (M14) the closest target Corvin with it's Pseudopod Attack: 10 Damage: 7 bludgeoning damage + 18 + 14 acid damage, clobbering Corvin for a total of 27 damage. Corvin is wearing his new armor which seems to be immune to the corrosive effects of the puddings acid.

Baik, Corvin, Xavier, Velmine, and Qu'oth are up 

(Uh oh)

Velmine has already given up on that fight, so, after telling the group of the black gate she found, she disengages and dashes with her cunning action before she moves back towards the party, she gets close to the wizard's body and starts making an examination on his clothes and anything he was carrying. (Seeing the log for the battle, the wizard died on K16, so Velmine will be on J16. If you give me a free Investigation check, I'll put it here, if not, we can save it for the next round, in case I decide not to change plans.)

Investigation Check: 31 (Passive Investigation 22)

Xavier reaches out a hand toward the ooze and shocking grasp lightning zaps it. 

Attack: 10 Damage: 5

Cursing as his spell (I'm assuming) misses the target Xavier retreats moving to L17 on the map next to Baik.  

(Most Oozes have negative dexterity, so this one's AC is probably below 10. I'm pretty sure you hit it.)

Xavier tries to cast shocking grasp taking 2 acid damage on contact with the ooze, however the ooze doesn't seem affected by the lightning. Then Xavier moves away from the ooze, allowing it to make an opportunity Pseudopod Attack: 18 Damage: 4 bludgeoning damage + 18 acid damage. Xavier is able to get away from the ooze, but takes a total of 32 damage to do so.

Corvin and Baik are up (also Qu'oth)

(Wait. Even if the creature is immune to lighting, if the Shocking Grasp hits, it still means the target doesn't get a reaction. The damage and reaction effect are two different things that both come from the result of hitting the creature. That's how I'd rule it, but I'll let it to the DM to decide. Also, why do these things keep rolling so high? They have a +3 modifier to attack and I've barely seen them miss.)

(Also, since you didn't say anything about it, can I assume I'll need to wait for the next round to see the results of that investigation? Just asking, since you didn't make it completely clear.)

 The way I look at it is the no reaction part is a result of the lightning coursing through the targets body, causing a short circuit for a few seconds. If someone can provide a logical explanation for how this would work differently, I might change my mind.)

Yes I believe you would have to wait for next round to investigate the Wizards body. 

(The way I look at it, the monster is immune to the lighting damage, not to the entire spell. I try to avoid using scientific arguments in a fantasy game, because magic is magic, but IMO the monster not being completely immune to the effects of the spell could be a case of the electricity causing no harm but still momentarily seizing up whatever animating force the ooze has got going, briefly negating its ability to form pseudopods)

Qu’oth will perform another flyby on the weakened ooze, helping whoever next attacks it.

 Same argument on the frostbite spell we had.  The spell effects them it just doesn't hurt them.  The magic has multiple effects and you could be momentarily jolted and shocked by lightning without it hitting you.  Is the monster immune to lightning damage or to status effect reductions?  Things can be immune to charm or sleep or poisoned and such.  The spell doesn't say if they take damage then they can't react it says they take some damage and they cannot take reactions.  The one doesn't create the other.  The comma between the effects of the spell make it read like a list of multiple things the spell does independent of each other

Ok I posted in the OoC thread with my decision and edited the above post. Xavier took a total of 5 damage from touching the ooze.

Corvin and Baik are up 

Baik blasts Sacred Flames once more at the ooze Xavier attacked.

(DC 16 Dex or 10)

 Corvin and his spiritual weapon continue to attack the ooze.

Sacred flame: DC17 dex save or 9 Damage

Spiritual weapon: Attack: 10 Damage: 9

BP2 dex save 12

Corvin's Sacred Flame washes over the 2nd ooze killing it. Do you want to start moving the Spiritual weapon towards the 3rd ooze?

(I forgot I hadn't already done Baik so here is his turn)

Baik moves 5 feet to get a better shot and the newest ooze and cast Sacred Flame at it (BP3 dex save 8). The ooze is caught by the holy fire. 

Eiren is up 

Eiren throws his skeletal hand up at the ooze (taking advantage from Qu'oth): Attack: 24 Damage: 7 necrotic

(Elven Accuracy to replace the lowest roll: 21)

He also pulls out his longbow, ending his Bladesong, and aims a shot (bonus action) at the ooze. Attack: 10 Damage: 6 piercing

Somehow or other there is a withered hand clinging to the ooze as Eiren's spell takes effect. Eiren then pulls out his longbow and shoots at the ooze, but he over shoots and the arrow is lost in the black pool. 

The Ooze, oozes forward towards the closest target, ending in O15, and attacks Corvin with its Pseudopod Attack: 7 Damage: 6 bludgeoning damage + 19 acid damage. The ooze misses Corvin, maybe because of the skeletal hand hanging around.

Corvin, Baik, Velmine, Xavier, and Qu'oth are up
