Penris, horrified at both the hag's oozing form and her claw slicing Vanyel's chest, moves again to attack with her dagger, aiming for the hand that injured Vanyel. 

Attack: 7 Damage: 6

Kip is still just trying to save fish unless one of his companions yell at him that they need his help. 

Penris' dagger slashes towards the hag's clawed hand; which darts away with amazing speed.  Vanyel brings his axe down hard upon the hag; but her slimy form slides out of the way, causing the axe to dig deep into the mud.

Grizelda slithers back.  A section of the moss covered flesh reforms, revealing sharp angled teeth.  "You are too weak too challenge me; I shall eat your flesh."  A spray of green burning ooze flies towards Vanyel.  (Grizelda: 8)  Vanyel pulls his axe out of the ground in time enough to step back out of the range of the slime.

Kip, Glitter flies out of your tail, helping to push the fish down the hole; the fire overhead, now moving onto the walls, blazing with an intense heat.

Penris narrows her eyes at the hag.  "You're disgusting," she says, lunging at the hag again with her dagger. 

Attack: 6 Damage: 4

EDIT: Adv on attack:  Attack: 21 Damage: 8

Vanyel growls in anger and frustration. "I will strike you down you ugly hag." He then charges her and once within 10 feet swings the axe in a giant downward chopping motion as if splitting wood and she was the wood. Attack: Unable to parse dice roll. Damage: 16

2nd roll for attack

20

Vanyel and Penris has advantage on the attack due to flanking.  Kip, you're about two thirds of the way through the barrel.  You may attempt the difficult check to try to push over the barrel as a bonus action this round.

As Kip continues to try to free the fish, he will squeeze his body between the wall and the barrel before attempting to push over the barrel by pushing hard with his feet as the smoke begins to fill the room. (Using my inspiration! 9) 

(OOC can I see the hag from my location inside the house?)

(No, the fight has moved towards the side of the house, and with smoke is filling the room, it is impossible to see.  However the fight sounds close to where you entered.)

Kip will just keep unloading the fish then, staying in until someone asks for help or all the fish are free.

Penris moves in, dagger in hand; bringing it down towards the twisted, deformed form, of the hag.  Vanyel charges in, startling Grizelda; forcing her to fall back, directly below where Penris' dagger is plunging.  The hag screams out as her twisted form becomes pinned to the ground; just in time for Vanyel to chop deep into her, severing a piece of flesh.

The hag writhes and leaps into the air, inflating instantly to her full size; bones and organs popping into place.  When she lands on her feet, you can see her full hideous form; green, knarled, and covered with warts, ooze, and blood.  She lands near her burning hut, hand on her most recent wound.

"Fine, fine." Her croaked and sinister voice says. "You found the evil witch, beat her up, burned down her home, freed her prisoners.  Now you ask me the questions you have for me and then I am either freed or I have to escape."

She looks from Vanyel to Penris.  "Been hearing the name Pluto a lot from the fairies; guessing that's one of the new Gods, and you lot are their champions.  Which of you belongs to Pluto?"

Penris looks quickly at Vanyel.  “Don’t tell her anything, Vanyel!”  She looks back to the hag, her eyes narrowed.  “We’ll ask the questions, hag.  How many do we get?” she says uncertainly.

After the fish were saved, Kip would leap out the window of the smoke filled house, unable to see and hear what was going on outside... The squirreling would immediatly slide a bullet into his sling. After coughing and choking a bit, Kip would spot the hag though his watering eyes and launch a stone towards the creature.

Attack: 10 Damage: 9

"Get away from my friends you wretched creature! You are no match for the power of Hope!" The squirreling would shout as he releases the stone.

Vanyel, still enraged desired to only learn just how many chops of his axe it would take to cause the hag to stop living. But hearing his companion asking a question he momentarily held back his rage and silently prayed to The Mighty for guidance before charging. "Mighty do I attack or hold back until we get more information?"

The stone begins to glow and you hear "Yeah!" from Hope, as she begins to arc the stone.  It beams the hag in the face, breaking her twisted nose.

Grizelda turns again to Penris, spitting out some blood.  "One less now." She replies.

Vanyel, you barely hear The Mighty say; "She admits defeat; watch to make sure she doesn't change her mind."

Slowly Vanyel begins to circle around the hag with the intention to cut off any route of escape while gripping his axe in preparation of attacking at any sign of aggression or flight, his eyes narrowing as he watched her. (insight) 4

The hag looks like she'll take any opportunity to escape; though none seem available to her at the moment.

Kip, realizing that there is no longer a fight going on would walk towards his companions. "So.. umm... are we done fighting her now?" He would say as his tail twitches behind him as he looks from the Vanyel to Penris. "I Think I missed something.. I was in the burning house.. it was loud and smokey in there... " He will say as he puts another rock in his sling.

Penris looks at Kip, still eying the hag warily.  "She says we get to ask her questions.  I'm not sure how many, though," Penris hisses through her teeth.  "What should we ask her?  Glitter, do you have any ideas?" she asks the sprite hopefully.  "OH! I know one question - how do we turn back the people you turned into fishes? And two - how do we defeat you and your boss?" she asks.  "Those are good questions, right, Kip?" she whispers.

On the farside of the burning hut, Kip can see a flutter of fish being led away by the sparkling shine of Glitter; towards the remnants of the faries land.

"Sounds good to me!" Kip would reply while rubbing his fluffy chin.
