This spell banishes one slot of skills per 3 levels of the caster from the target creature. The skills which may be banished are chosen by the caster. Skills which may be banished are one point of THAC0, one spell, one hit point per Hit Die to a minimum of half hit points (not per level but per Hit Die), one proficiency, one point of an ability, one psionic power, or even one complete memory block (the last is under DM jurisdiction) per slot. The target creature has a saving throw versus spell per targeted skill; if it succeeds, the spell fails. If it fails, the target loses the specified ability. It is possible to target only one skill with all open slots (if a 15th-level caster only wants to banish a fighter's THAC0, he could try it with all five slots at once, causing the fighter a -4 to the saving throw, as one slot is used to attack the THAC0 and the remaining four slots are used to reduce the chance to save). The caster of the spell can also split these slots on several different abilities. The banished abilities are lost for the duration of the spell. Afterwards, they automatically return at full Strength. During the time the affected creature is only able to use its lost abilities like any normal person (if proficiencies) or at the reduced ability score. It is not possible to banish curses with this spell.
The material component is a lodestone which is shaped recognisably like the target creature. In addition, a part of that specific creature has to be attached to the lodestone (a hair, a piece of skin, a drop of blood, etc.). This spell requires some form of direct mental or physical contact with the target creature throughout the casting (ESP, telepathy, a tied rope, a hand on the arm, etc.). If this is non-existent, the spell fails.
