ToME: the Tales of Maj'Eyal

So, I seem to have managed to accidentally bugged the Fortress's applying the Cloak permanantly.

Beat the beast, then accidentally immediately agreed to put the cloak effect on me before I had any actual power. It went to -10 power and I had no lasting Cloak of Deception effect.

Try putting it on then taking it back off again. That seemed to work for me.

That worked, thanks.
