Release Weapon

Release weapon causes a weapon-wielding creature to drop its weapon immediately. A successful saving throw vs. spell means that the spell had no effect. Unless aware of the caster, an affected being will likely believe that he dropped the weapon due to his own clumsiness. Recovering the weapon requires a full round, unless the weapon was dropped into a pit, over a cliff, etc. For every five additional levels of the caster, one more creature can be affected. Thus, a 6th-level wizard can disarm two opponents, an 11th-level caster can affect three, and so on.

This spell applies specifically to weapons or objects being used as weapons. It does not cause other items to be dropped.
