Drizzak
In one quick movement, Drizzak caught the vials, shook them and then guzzled them both in a hurry. He began to cackle once again as his cell became unlocked. These elixirs were different to the previous, mixed with different constituent ingredients but overall the same effect would come of them. Absolute carnage.
As his cell opened, Drizzak hopped over to the corner of the room and donned his equipment once more. Costume, dagger, crossbow and trusty pants. All were thrown on, and the costume bagged, as he began to froth violently at the mouth. He shook, more than usual, as his chattering cackle devolved into a high pitched shriek.
"Get your stuff, their in the corner. No time to stop, bring the fight to that hooded bastard."Drizzak turned to his saviour, and smiled wide. Frothy red leaked from the corners of his mouth as he growled. His face elongated and thinned to become something of a snout, as his back exploded into a pair of membranous wings. His skin took on the same red tone and his fingers became long, skeletal claws. He became skinnier and... sleeker overall.
And then he burst into flames. Again.
Drizzak screamed with glee as he took off, one flap of his mighty wings sending him forward.
"DRIZZAK TEAR BONE-FACE APART. PICK TEETH WITH TEETH!" His brilliant orange body burned a bright bee-line. Straight into the thickest part of the undead group as he collided with them in a puff of flame.
