The Forgotten Wish

Oren would use the first round to:

Run up and get closer to the elf/blob.   He would stop 20 feet away.

Second round:

Oren takes a deep breath, looks around to make sure his friends are also nearby and attacking, then he would step up the creature and take a swing at the thing with his warhammer.  

He would be careful with the swing, trying to hit the blob part and not the elf.  Attack: 8   Damage: 7

"C'mon'" he yells, and (Using action surge) attacks a second time.   Attack: 19   Damage: 11

After his attack he looks back at his companions, hoping they have luck taking care of the creature.  (Actually, he is hoping the many rogues get lots of sneak attacks due to him being close to the creature now)

Oren wastes no time charging straight in., which in turn leads to the monster running in his direction first, sprinting,  and the two of them end up practically next to each other- Though the beast doesn't yet find time to strike.

Although maybe it doesn't even need to. While Oren had his warhammer ready and braced, now so close to this hideous thing, there is a nagging, oppressive feeling in the back of his mind...

All at once, an invisible dam breaks, and it's like a flood of these unnatural voices break into Oren's mind all at once. He finds himself frozen to the floor, completely frozen for a split second, until he lets out an involuntary scream. Whether it are these voices overloading him, or taking direct control, he finds himself raising his warhammer with little regard as to where he is actually aiming, as it looms over the elf.

...And luckily, still comes smacking down on the horror first, rather than the elf.

(Action surge has been refunded)

Following this, the creature snaps, and one of its many hideously large mouths lurch in Oren's direction.

Attack: 13 Damage: 13

And the attack comes short.

(There are a bunch of held actions. It technically didn't move closer, but I will accept it attacking Oren as an initiative to shoot. Asimi, because Oren retroactively moved as close as possible, would Asimi have joined to be as close as possible?)

(No, I'll leave Asimi where she is to avoid any more potential retroactive confusion. Can just maintain that she's still somewhat unsure about the scatter shot nature of the group's response and defending the bulk of them.)

Breldo's been studying the creature, and has gained somewhat of an understanding of it, at some primal level. He lifts his crossbow and fires on the blob, seeking to help put it down before it does something foul to Oren.

"Oren! Careful!"

Attack: 22 Damage: 11

Rick helps by distracting the creature,

"Hey Mouth monster? What were the useful things and where can Rick find them?"

(it seems like notifications might have been broken again for a bit, so just giving a poke I'm checking people with held actions.) 

((I'd said that Breldo was standing ready with crossbow out, but he'd been trying to study it (rolled meh), so I wasn't considering him to have mechanically held his action, so above crit is his action on his proper turn.))

Nuria looses the arrow she had prepared, while Breldo uses what little knowledge he just gleamed to aim carefully. His arrow seems to hit a weak spot, piercing almost all the way through the hideous beast, but causes it to be dragged by the sheer velocity of the projectile, partially tearing it off the host as it collapses to the ground.

Though its rapid, undulating movements there betray that hit didn't quite kill it yet, vigorous even now. While the elf, now seemingly freed, stumbles for a moment with a dazed look, that strange goop spreads underneath the creature quickly, catching both the elf's and Oren's feet within.

Khond falters for a moment, then grits his teeth and charges, drawing his rapier, with intent to strike only the abomination.  If he's somehow got 30' between himself and the thing (Which I find unlikely), he'll add in a charge attack with his hooves.

Anticipated WIS save: 7

Rapier attack: 15
Rapier damage: 8

Charge Hooves Attack: 9
Hooves damage: 4

(Awaiting Khond's action for now, but will presume that he will be unable to attack this turn.)

Sylvera, looking quite pleased with herself after her last attack, proceeds to throw her boomerang again. 

Action:

Attack: 22 Damage: 5

With the battle now well and truly kicked off, any remaining hesitation Asimi may have had is gone as the elf rushes in to join the fight. Sprinting towards the separated blob of flesh she wastes little time in attempting to drive her halberd down on it.

First action is running 50ft to get within 10ft of it. Or 60ft to get within 5ft if there's no valid space.
WIS save: 12

Using Action Surge to attack using her halberd with the second action.
Attack: 13 Damage: 4

Sylvera's boomerang strikes again, more gibbering noises made, but nothing coherent, almost as if panick. Asimi joins in by quickly rushing in, and striking at the beast as well by exerting herself. While she doesn't seem affected by the strange sounds just yet, she does need to step in the goop that now spills from it in order to strike. Certainly, nothing that might come back as an issue.

The elf, for his own part, in tattered clothes that barely survived a long, long time of being within these halls, seems... Surprisingly calm, given the circumstances. His movements a bit sluggish, his eyes slightly lidded, glancing briefly at the twisted mass of flesh, before at the slick oil-like substance that protrudes from it, and tries to lift up his feet.

The elf takes a surprisingly nimble leap out, and then shuffles just a bit further away, before turning to watch the scene almost apathetically. They do, however, speak:

(Do you speak Elvish?)

Acting completely out of fear and reflex, Nuria looses another arrow at the blob thing.

To hit: 9 

and she misses….
