Thanks for the detailed bug reports, sorry for the delayed response, I've been trying to finish the latest update up before looking at it. I believe I have it fixed now with patch 0.43.5. There were two issues. First, the game was coded to almost never use the skill that was bugged, giving massive priority to her weakest special ability instead. I was probably testing the ability for some reason or another, and gave it high priority to ensure she'd use it during my test, and didn't change it back. Second, the bugged skill doesn't actually do any damage on it's attack. For some reason, a plugin I added hates for any damage formulas to not have values, even though that's fine with the base game. I originally still used the damage formula to apply the healing state onto Alexandra upon cast, but I just switched that to a common event instead. Let me know if applying that patch doesn't fix things, thanks!
