The spell I see that neutralizes thugs more than any other is Paralyze.

There is also the E5 spell Petrify, which says in the description that even if it is resisted, you still get paralyzed for a while. So in theory that would work, but I have never seen it used.

Also, the Acid series of spells (Acid Bolt, Acid Rain,...) has nothing that resists. I think they are AP, so 30 protection + regen should be a decent defense against a 15 AP spell. But less protection than that or no regen and spam it and that will work.

There's also Mistform. Every attack that would normally do damage has a 1% chance of popping the mistform. I've lost more Oreiads that way...
