I guess something needs the poison random enemy trait and Venoxia drew the short end of the stick. The problem is that poison in its current state isn’t good and random application makes it even less usable. Once you poison something, it doesn’t need to get poisoned again most of the times, making it even MORE useless.
If it was up to me, I’d make poison a random enemy on 4-5 match a universal trait, move that to the 2nd slot, and give a random stat gain each time something takes poison damage as Venoxia’s 3rd Trait.
Then… I’d completely get rid of Venoxia’s current spell and try something new. Anything. Even summoning a poisoned Bunninog would be better. (half-joking)
