You can scribe scrolls of epic power.
Prerequisites: Scribe Scroll, Knowledge (arcana) 24 ranks, Spellcraft 24 ranks.
Benefit: The character can scribe scrolls that exceed the normal limits for such items. For instance, you could scribe a scroll with spells of greater than 9th level, or a scroll with a caster level greater than 20th. Even this feat does not allow the character to scribe a scroll with an epic spell. See Creating Epic Scrolls for details.
