How do you do that? Please tell, I'm sure more people than me would like to know!
Download and install IEMod from here nexusmods dot com/pillarsofeternity/mods/1/
Then for example character has name - Zhanna
IERemove Zhanna BattleForged
FindCharater Zhanna (you get string like Player_New_Game(Clone)_2)
AddAbility Player_New_Game(Clone)_2 BattleForged
Thank you! I will try this as early as I can.

Supposedly it's supposed to be fixed in 1.05, although I don't think it works retroactively... And Cheat engine cant remove it either. Might try cheat mode in the IE mod, maybe that can remove active effects.
