Perverted mind

And another question: how do you use the "berserk" spell? It doesn't work for me, it seems to be glitching. I remember it used to work a long time ago. Now, the icon of an open book flickers, no matter what I hover the cursor over – whether it's my units, enemy units, or an empty cell. When I click, the spell seems to be cast, but it doesn't target anyone. I have a licensed "complete collection" version.
