Theo nimbly dodges out of the way, performing some fancy acrobatic moves as he draws a second blade and rushes forward, both weapons sinking into the owlbear's flesh, causing it to roar in pain

Elsenia, on the other hand, is knocked to the floor, spread-eagled on her back. Just then, Theo makes his assault, giving the druid time to climb to her feet, and then deliver a swift strike with her fist, which glows with dark energy

I'll reroll the hit roll real quick: 23

Ooboron, meanwhile, lets out a loud trumpet, a dark spirit leaking forth from his trunk, and it slithers towards the Owlbear, becoming a cloud wrapping around its head, filling its primitive mind with visions of fire and death

INT save: 3

Weaver, her glittery fairy dust having been succesful, pulls out a canister of something foul, and shoots a jet of the stuff at the rampaging beast. It hits the monster square in the chest/

CON save VS. Ray of Sickness: 23. On a failure, the Owlbear is also poisoned.

The owlbear, bloodied and battered, roars with a primal ferocity, and opens its beak, attempting to swallow Theo.

Beak Attack VS. Theo: 19 to hit. Hit: 6 Piercing damage and Theo is grappled (Escape DC 15)

Aurora, seeing her friend in trouble, sends out a sonic boom, which crashes against the owlbear's beak as she takes the Help to give Theo advantage on his escape check.

Party, GO!

Weaver sees the Owlbear knock Elsenia prone, but she's covered in spores, so she doesn't look too bad - but when her buddy Theo gets snagged by the beak, she freaks.  "Theo!"  She rushes forward, pulling out a canister with a spray bottle attachment at the top, and once she's next to Theo, she'll spray him with a minty smelling substance that heals him for 8 HP.

(casting [spell[Cure Wounds[/spell] on Theo)

Elsenia watches in alarm as the owlbear tries to devour Theo. Even after all the damage they've caused it, the beast is still on its feet. She never realized just how powerful and strong an owlbear was, but she is unfortunately finding out right now.

She recites an incantation, focusing her ire on the owlbear. If her spell is successful, the creature won't be able to see its targets, and that should help them out quite a bit!

(Save DC is 14 CON)

Theodore wiggles and struggles against the jaws of the owlbear. He cries in pain not noticing his wounds almost instanly heal (THANK you btw)

Continuing to concentrate on his previous attack (I'll let you roll the 1d6 psychic damage on the owlbear's turn), Ooboron puts his hands on his hips and says loudly, "Your critical thinking is like a barbarian’s spellcasting — non-existent."

DC14 WIS or take another 3 psychic damage and have disadvantage on the next attack roll it makes

Weaver rushes forward, using a concoction to heal her furry friend Theo, who is a whirlwind of steel as he leaps and dances, jabbing and slicing with two vicious strikes which both cause the Owlbear to scream in pain, releasing the Harengon from it's hold.

Elsenia, speaking ancient words of forgotten power, sends forth a shroud of darkness to blind the beast. The floating motes of necrotic shadow that surround her assault the Owlbear, causing it to howl in pain.

Owlbear's CON save VS. Elsenia's [Tooltip Not Found] spell: 13; Owlbear's CON save VS. Elsenia's Halo of Spores feature: 6. Damage: 6 Necrotic

While Ooboron shouts forth an insult so good he almost feels bad for saying it despite the fact the owlbear is dumb as rocks.

Owlbear's WIS save VS. Ooboron's Vicious Mockery spell: 16

Did the owlbear eat anybody? Or are we so awesome it ran away?

The owlbear shrieks in pain, the onslaught of attacks severely injuring it. The tendrils of dark energy which wrap around Elsenia strike it, and it falls limp to the ground, reverting to a wooden set piece. Out of the corner of her eye, Weaver notices something black shining on the thing: more of the strange goo.

Ooboron climbs up on stage to check on his friends and to inspect the inert owlbear (from a safe distance). "Does anyone need healing? I have a little bit more magic in me."

Weaver carefully grabs another sample of the goo to compare it to the earlier samples she's taken.  She wants to see if there's any change in composition from the earliest samples to now, to see if new information can be gleaned.  

"It would be nice if these things could happen NOT at a party or during a fun time. Then again, that would mean we were actually trying to find a bad time. HA!"

As the party talks, and Weaver takes some more goo (I wonder what potions I could make with this?), an older human woman in Silverquill professor robes rushes up to you, worry coloring her face. "Goodness! What happened here?! Is anyone hurt?" She says, then notices the gaping, bleeding wound on Theo's arm from the owlbears beak. "Here! Take this!" she says, handing the harengon a dark red potion.

"Aw it's just a scratch ma'am, thanks though." he smiles at her and pockets the potion.

"Oh please. You look injured. You should drink it. After all, these are dangerous times here at Strixhaven" she says with a grin and a wink, then subtly motions with her hand for the four of you to crowd closer. "Something is going on at this school." she whispers to you "Something not good. I'm sure you've noticed these 'incidents' throughout the year. I want to get to the bottom of it and expose the truth in the Strixhaven Star" she nods to Weaver, referring to the school newspaper which the fairy has been helping curate this year. "The school year is almost over, and we need to get to the bottom of this. Are you interested?"

Theo nods, "Oh absolutely! These shenanigans are putting people in danger. That is just not acceptable. You can count on us! Right best friends?!"

Weaver nods her agreement. "For sure!  There's still so much to do, though - what's your name, professor?  Maybe you can help us."

OOC: The school year is almost over? I've failed two out of the three exams. I'm doomed!

Ooboron nods, crowding in closer to hear how he can help.

"I'm professor Tochsk-ty. And thank you for your help. A fellow professor, Valentin, has agreed to help us if you can gather some samples of this substance, which seems to be originating in the Sedgemoor swamp on Witherbloom campus. Are you up to the challenge?" Professor Tochsk-ty asks.
