Hey Larian,
playing with Ifan being a Summoner. During combat dominate mind was used on him while he had a non magic champion incarnate, according to the combat log both Ifan and the Incarnate were charmed from the same skill. I was able to use Peace of Mind on Ifan before his turn and he was cleared of Charm, however the Incarnate was not. It seems like a bug to me that the Summoner was cleared of Charm, but the summoned wasn't. Especially considering it took 1 Dominate Mind skill use to charm both of them. Surely if that is the case Peace of Mind would also clear both of them?
