Rey's Wizard Lizard

This build is around the Lethal Venom's insane scaling, letting you do up to 1000 damage with it by late game with no cooldown

Shoot->bullets activate venom->ult->venom procs->venom procs again after ult->press 2->venom procs a third time and kills them

This crazy build idea is from my eternus friend twitch.tv/thebigdream1
