One of your personal emanation spells becomes permanent.
Prerequisite: Spellcraft 25 ranks, ability to cast the spell to be made permanent
Benefit: Designate any one of your spells whose area is an emanation from you, such as detect magic. This spell's effect is permanent (though you can dismiss or restart as a free action). Effects that would normally dispel your spell instead suppress it for 2d4 rounds.
Special: This feat may be taken multiple times. Each time, you select a different spell to become permanent.
