Feeblemind

Tips
Enemy necromancers in level 10 missions may cast feeblemind on you. Fortunately, they will target it on anyone, not only spellcasters, so some victims (such as barbarians) might be only minorly disabled. Having a 1 intelligence is less disruptive in DDO than in PnP, because only abilities which directly use intelligence or charisma are disabled. You can still communicate with PCs and NPCs, and remember which end of a sword to stick in monsters.

Currently (July,16,2006) this spell can only be removed by death or a Restoration spell. Heal, which is castable by a Brother at any inn, is supposed to remove it as well, but at this time is bugged and does not.
