Permanent Emanation

(Epic Level Handbook, page 64, DnD 3.0)

[Epic]

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 effect is permanent (though you can dismiss or restart it as a free action). Effects that would normally dispel you 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
