The spell is decent, but the furry still moves first, and Rezara is right next to her with low HP...
I take it the spell is based on a weapon attack with all the bleeds and crits?
Yes.
Because Rezara doesn't have Renavan's conviction, there's a funny situation: she can use the spell to knock herself off the battlefield)
Scared of her own power, I guess.
Does Astarothia have a portrait?
