Feeblemind

Tips
Enemy necromancers in level 10 missions may cast feeblemind on you. Fortunately, they will target it on anyone, not only spell casters, 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.

This spell can be removed by the Heal and the Panacea spells or by any potion of mneumonic enhancement.
