Problem is that fleeing isn't a viable option when a thief can stack a lot of traps too.

And that's before you consider what would happen if the thief chose to call in an accomplice during the very long ko periods. Flaaayin can take many magi solo.

It's a lot worse than deafen. If deafened, you can use a wand to recall.

It's worse than mage forget, because unless I'm mistaken, the anti-forget edge does nothing against the forget effect (same as I think the anti-poison edges do nothing against the poisons to begin with). I could be mistaken on this though.

Effectively it's forcedual on a person who can't use their class abilities.

I generally like the idea of the ingredients but the problem with such an approach is that once these things become common knowledge there's a massive balance issue (unless some counter also becomes common knowledge).
