Ancient Permanency

This spell affects the duration of certain other spells, making the duration permanent (i.e. comprehend languages, detect magic, true sight). The magic-user casts the desired spell and then follows with the permanency spell. Each permanency spell lowers the magic user's health by 100 hp or 1 constitution point (the constitution point cannot be regained without the use of magical items or the use of a  Greater Restoration, Regeneration, or wish spell). The magic-user cannot cast these spells upon unwilling creatures without making a rivaled wisdom save at disadvantage. in addition to personal use, the permanency spell can be used to make object/creature or area effect spells permanent (i.e. stinking cloud, wall of force, sending stone, banishment).

The former application of permanency can be dispelled only by a magic-user of greater level than the spell caster was when he or she initially cast it. The permanency application to other spells allows it to be cast simultaneously with any of the latter, but the permanency can be dispelled normally, and thus the entire spell negated.
