Vampire Lissandra

Appearance... Similar to coven skin but black-red or maybe some robe with a hood and instead of ice following her everywhere~ turn it into black smoke or pool of blood!

Abilities...

Instead of throwing ice~ let her throw bolt of dark magic looking like black smoke or maybe blood bolt.

Instead of summoning a hand~ make her summon a bat made out of dark smoke. When you teleport to it... Explosion made out of smoke! (Blood?)

Ultimate? Prison made out smoke, blood or swarm of little bats. Maybe even a simple coffin.

Fast travel and recall? Bat transformation!
