Urukar grumbles as he approaches his fellow half-orc, "That makes no sense, tiefling...".  He spies the other creature in the room, and runs towards it, hoping to obliterate it like that last one.

(Urukar, should've made it more clear. That last vicious mockery killed him...sticks and stones broke his bones and words finished him off)

Urukar and Valen gang up on the brain thing, pummeling it mercilessly. They step back...and surprisingly, it is still standing. The tentacled creature looks at Urukar, speaks some unintelligible words, and points. Urukar, I need a wisdom save.

The brain leaps at Valen, slashing with its claws:

Attack: 24 Damage: 9

It lands, and looks almost like it's straining towards Valen. Intelligence save from Valen.

Valen int save: 17

The brain leaps at Valen's face out of nowhere, catching him completely off guard and slashing deep into his face and neck, narrowly missing vitals but producing a lot of blood. You also feel something probing around your mind, but you're able to push it out.

Rayner: "Someone take Master Floon to safety! I'm gonna try and follow that squid creature!"

Auric:

Seeing the brain-like creature attaching itself to Valen, Auric moves over and slashes at it with his battleaxe, trying to free his companion from whatever monstrous thing the brain is trying to do to him!

Mal’thrae shoots at the brain creature (unless it’s dead, in which case he shoots at the tentacle creature.)

Attack: 21 Damage: 14

 Urukar, you feel the tentacled thing infiltrating your mind. It speaks in your head: 

 You have no choice but to obey. The thing has dominated your mind.

With that, the creature pulls something out of its robes and moves down the side hallway.

(Rayner, you can amend your post to chase after it if you'd like)

Valen uses Wrath of the Storm
When a creature within 5 ft. that you can see hits you with an attack, you can use your reaction to cause the creature to make a DEX saving throw (DC 12 or it takes 8 lightning damage (half damage on success).

Between the lightning storm and battleaxe, the brain is turned into a steaming pile of gray matter. 

Mal'thrae's arrow and Rayner's glaive find their mark, and the creature turns, it's alien eyes glittering with anger. In Urukar's head:

 It continues its journey down the hall and out of sight.

A dumb look comes across Urukar's face, as he appears to be listening to something only he can hear.  He suddenly snaps out of it, letting out a blood-curdling roar, veins popping out the side of his head.  The half-orc drops his greataxe, and roars again as his massive bulk moves like lightning in the direction of Rayner!

Urukar goes into a rage!
