Advanced Dungeons & Dragons 2nd Edition Wiki
See also Feeblemind (Wizard Spell).

A spell solely for employment against persons or creatures that use magical spells, feeblemind causes the victim's brain to become that of a mo­ronic child. The individual remains in this state until a heal, restoration or wish spell is used to do away with the effects. The spell is of such a nature that its chance to affect the target creature is gener­ally enhanced (saving throws are lowered).

The spell has no material component.

Notes: Common for clerics (Updated from 1st Ed. PHB).
