"That's interesting.  I didn't know any of that.  Whatever the case, we've put an end to that monstrous creature.  We did attack it first, but it didn't really seem like it wanted to talk..." Athos goes silent as he gets lost in thought.

From what you hear, the next encounter is a couple of oozes. Black puddings to be precise. (and although a 20 gets you the creature, it doesn't get you abilities. If you happen to know anything about them without looking it up, you can choose if your character knows it) 

"Oozes will be a bit different from a drider, at least they don't have the same kind of sentience.  Shouldn't be that much of a problem." Athos says confidently and busies himself getting ready for the next fight.

"Ooozes?! Hmm... Those will be treaky. But, you have the right of it about them not being smart." Gimmond said in agreement, yet held up a finger in a halting gesture. "That said, there not to be underestimated. Of heard of some being as bad as rust monsters, and others capable of swallowing a whole platoon!" He further asserted, only to moments later chuckle sheepishly and add, "But, of course some of this might be just exaggerations. Doesn't mean we shouldn't be cautious, and ready to adapt if the need arises! Understood? Good." 

The fight is due to begin. The arena is back to its default look, with default lighting. You are free to reposition yourselves and/or take an action in preparation before the oozes are released. And then because they are quite slow reacting, you all go first.

(the slimes come through the center hole. The grate doesn't open, the lift brings them up and they just ooze through, slightly rusting the gate) 

Without fully knowing what sort of tactics might be best for dealing with the ooze, or oozes as the case might've turned out to be, Gimmond defaults to the standard approach of starting out just head of Zumfir, ready to intercept any attack that might be headed her way. But, seeing an opportunity for a more aggressive play, he'd immediately rush the creature with his spear and assault the sludgy mass thrice over in a sharp, calculated series of prods to test the creature's defenses.

Mo: Using full 30ft if needed to get within melee of ooze.
Ac: Attack nearest ooze with a most vicious spear!
Attack #1: One-Handed Vicious Spear vs Ooze(AC ??) - To Hit: 9 For: 14 Piercing Damage.  
Attack #2: One-Handed Vicious Spear vs  Ooze(AC ??) - To Hit: 26 For: 17 Piercing Damage. (Accidentally rolled part of the damage twice despite SA only being one turn, so ignore the 14) 
Ba: Polearm Strike vs Vicious Spear(AC ??) - To Hit: 18 For: 17  bludgeoning damage. (Rolled a 2nd time w/ Savage attacker for current results)
Sapping target with first to hit.

Athos will grin and follow Gimmond in and attack with his battle axe. 

14 to hit for 8 slashing damage with a smite added for 8 radiant.

And a 22 to hit for 15 slashing damage.

And a CON15 save or be knock prone from Topple.

Seeing the gaze corrode as the oozes pass through it, Twinkle doesn't like the thought of touching them.

The monks limbs begin to darken slightly as she summons fire. The slimes probably wouldn't like that. [Elemental Attunement]

She then rushes forward, staying well away from the goopy enemies, bombarding them with a series of strikes from 15 feet distance, testing them for weaknesses by invoking the power from her magical wraps on the last two strikes.

Action:
Attack 1: 13 damage: 7 fire
Attack 2: 23, damage: 9 fire

Bonus Action [Flurry of Blows]:  
Attack 3: 16, damage: 14 force
Attack 4: 18, damage: 14 force

Gimmond, all three attacks hit. But you take 11 acid damage from it as your attacks hit. The acid doesn't seem to be affecting your weapon though.

Athos, you slice through (I assume the same one?) and the blade deals no damage. The smite however does affect it. Rather than deal damage the slime splits into two smaller ones (starts large. Now there are 2 medium and one large). With that in mind (as well as confirming if you did target the same one) I will let you adjust your second attack. You also take 8 damage when you hit. Topple seems to have no affect on the ooze, being such that there is no "right way up" (immune to prone). And your weapon gets a -1 to attack rolls as the acid starts to eat at it. 

Twinkle, all attacks hit. Both damage types seem as per normal in terms of damage. Based on the wording of the ability, having reach doesn't affect the acid damage (it just states hitting with a melee attack roll) so that is 12 acid damage. I also need to know who you targeted.

Zumfir to act as well.

(As I haven't formatted rolls for colour, Athos had max acid damage from his one attack. Both Twinkle and Gimmond had a min damage roll within their rolls) 

Athos wouldn't hit it a second time if he saw it have no effect besides splitting it into two creatures.  "Hey, looks like my attacks are doing nothing to these things." he'll say to the others and then re-evaluate his strategy.

"You can always take a page out of Twinkles book, and show it what for if you feel brave enough!" Gimmond called out and gave a pained grinned.

(coughs in forgot to log in)

"It seems like slicing them will just create more- do you guys have any contundent weapons? Like maces? use your shields, too!" Zumfir warns, throwing his Mace towards Athos, hoping that the warrior would follow his advice. 

Then (hoping that it was a free action) , the cleric whispers a prayer, and a moonlight hammer appears before him, quickly spinning and hitting one of the oozes who was attacking Athos.

Cast: Spiritual Weapon ATK: 17 Damage: 8 FORCE damage

Twinkle yelps as acid rains in her direction. She would also target the medium slimes first.
