Mezomel Luperfang

Mezomel Luperfang, the scion of moonlight, is the originator of the myth that Skinwalkers are influenced by the moon. Mezomel was originally a human traveler in the land of the Yakai, who happened to fall victim to a kitsune shapeshifter that lured her out into the woods one day. As she chased her paramour through the woods she fell into a den of wolves, crushed several pups and flushed with adrenaline, killed the den mother, who promptly had attacked her. Forever more she was struck with the Skinwalker curse.

BASE FORM

Mezomel buffs herself with her A3 with three good nuking buffs (Increase Attack, Increase Critical Rate and Increase Critical Damage) before it grants an extra turn to roll into either one of her A2 abilities. With a 3-turn cooldown, you have the option to switch over to her alternate form without them running out. 

Her Scarlet Crescent, base form A2, ignores/neutralizes most significant defensive protective buffs but very importantly, it doesn't ignore any defense. So keep Savage/Lethal gear and Helmsmasher in mind when building this nuker. This ability also blocks revives if it kills a target, which is crucial in many areas of the game.

Her A1 can decrease defense to further shred her targets. Her passive ability can help heal her up and will place a Revive on Death buff if she happens to kill any enemies. Mezomel is a damage dealer through and through.
