As SP has been made aware Zahra and her + 50 % life mechanic is bugged, especially in combination with Uriel's Essence, causing dead monsters to be revived spontaneously, dead monsters still being targeted by the ai, et cetera.
Her protection skills apparently cannot be removed either.
When can we expect a fix? I would like to be able to actually use her at some point. And while you are busy fixing her, maybe take another look at her skills as well. Not worthy of a warmaster.
