dredknightThis is different bug originating from ToE and already reported by fktifzobr@mail.ru over here.
I have put it in my queue but is low priority for the moment.
I agree, this is a low-priority bug.
What I noticed was that Frenzy was always applied for 2 turns even though the rest of the debuffs were at an advanced level.
Most likely, the skill level for this Frenzy is not spelled out, but somewhere in the code it is hardcoded = 2 (and another +1 = 3, if there is an expert Frenzy in the book, and this +1 was fixed)
