Larry’s internal matrix is tingling with the magical energy that seems to be discharging left and right around the room…

With the many-limbed creature down, he spies the mage across the room, seeing them slightly distorted, looking around the kind of heat haze coming from the swirling sphere in the centre of the room.

He wastes no time and moves in a smooth arc left around the sphere, leaping the furniture blocking his way and skirting dangerously close to the sphere itself. As he passes the sphere, within inches, there’s a freak second when, in whatever passes for Larry’s mind he sees himself being pulled and pushed in every direction by the magic and ‘spaghetti-ed’ out infinitely long and thin… before the moment passes… his body just the same as always…

Disoriented nonetheless he makes it to the mage while already winding up for a flying-double-scissor-kick followed by a frost-encrusted ice punch to the chest, before landing!…

Scissor kick #1: Attack: 17 Damage: 7 (bludgeoning damage)

Scissor kick #2: Attack: 24 Damage: 10 (bludgeoning damage)

Ice punch: (bonus action): Attack: 17 Damage: 11 (cold damage)

He says calmly while he attacks, “You really must get your coat and leave the Mistress’s tower!… Your being here simply won’t do… Not at all…”.

”If you don’t have a formal invitation you must go immediately <thwack>…”.

Larry feels a crack of something other than ice as he punches the mage in the chest, but the unwelcome visitor is still standing.

((stunning strike… Con save DC13))

((just 1x Ki left now))

Chaos ripples through the mage as he swells in size, Larry now only reaching up to his waist.

Con Save: 18

 The mage shakes off Larry's strike despite the blood that they spit up. Desperate, they scream at Larry, darts of energy raining down on the metal man as the mage throws a lever, showering that half of the room in sparks and flickering energy as the sphere pulses and begins thrumming louder and louder, the tower rumbling and shaking beneath your feet.

Magic Missile: 16

Larry collapses as the darts strike home, slamming him around with a metallic cacophony.

((Larry is down))

Keller casts invisibility on himself and then moves quickly into the room, over the body of the abomination. He runs over the table, aiming for the mage, and seeing that the mage just flipped a lever, and the sphere is getting worse, he, with cunning action, will take a bonus action to dash to right next to the mage. Hoping for a free object interaction here to be able to flip the lever back to what Keller hopes is "normal."

Assuming this works, he mentally messages the others "I'm invisible, just tried to undo whatever they unleashed with that lever, hoping the tower doesn't come down on all of us!"

((Keller, looks like you had spent Tides, so casting invisibility triggers a surge from you?))

Hmm, not sure I remember that, but seems likely! 

Tides: 40

((I'm going off your sheet, so toggle it back, and keep in mind you've got the Tides available to get advantage with!))

Keller vanishes, and there is the Patter of quiet footsteps as he dashes into the room and throws the lever.

 Storm's body (bodies?) surges with chaos, rippling through the room and altering reality.

Bolt gets nauseous as the chaos churns through her, as Storm starts floating higher above the sphere as everyone vanishes.

The rumbling of the tower subsides a bit with the lever flipped.

Storm 4 ((9 round chaos surge))

Bryn looks as everyone vanishes and quickly saves the location of the mage in his brain he than points his rod to the location and a chaos bolt shoots out (creature in range, not creature that he can see; and straight roll because advantage unseen attacker, disadvantage unseen defender?)

Attack: 9 Damage: Unable to parse dice roll.

While black moves in waiting for any friend or foe to appear, when one does he will move next to him (friend or foe)

Bolt continues to where she last saw the mage, and if she can make it, chops with her axe.

Attack: 10 Damage: 7

She will burn her last booming charge if it hits.

((Rolled with disadvantage))

((It's like I'm rolling for the two of them again! Bryn had Tides spent, so casting chaos bolt triggers a surge, if you want to roll a d100, Secret?))

((Unseen vs Unseeing I'm saying is flat roll (advantage/disadvantage), but you still need to know where to attack. Since the Bolt is poisoned for 1, she would have disadvantage from that, but for this attack while invisible, the advantage cancels out any disadvantage, so it was a flat roll for her too. Too bad her first roll was the low one.))

((Keller still needs to pick where they're porting to. If you were wanting to have kept protecting the lever, you'd still need to port, but could port 5ft above the lever? I'll resolve the mage's turn and update maps later today.))
