Shathra healing is NOT working!
I'm using Shathra in AQ. She is awakened, sig 60, meaning she is supposed to get a regen passive healing 3.9% of BASE health per vengeance at the start of each fight.
I got hit early on, putting her at 20% health. I then fought the next 3 fights with her to heal back some health thanks to her sig. I fought and won all 3 fights with her, taking basically no damage in any fight.
She got the regen passive in each fight, but i never healed more than 1% health, even with 3 vengeance! I did not have any heal block or health reduction effect in any fight.
My best guess is that Shathra's sig is granting 3.9% of STARTING health, rather than base health, per fight. Either that, or this ability is simply not working!
This was in AQ map 6, with the "power through sickness" modifier, and my bonus buff was defensive measures, which has no effect for Shathra. Playing on a galaxy s25+.
