Increases the duration of the spell it is cast together with. The DR of the permanency is added to the DR of the spell it is cast together with and the desired (set) level of one of the spells. The level of the other (not set) spell is determined by how much the roll exceeds this. If the spell is cast on a living creature it increases the duration by 5 steps + 2 steps per level. If it is cast on an object or area it increases the duration by 15 steps + 2 steps per level. Casting a permanency spell permanently reduces your MA by 1.
