Master Staff (Feat)

You can power a magical staff using the power in your own aura instead of charges.

Prerequisites: Caster Level 21, Creator (Feat)

Benefit: When you activate a staff, you can substitute a spell slot instead of using a charge. The spell slot must be one you have not used for the day, though you may lose a prepared spell to emulate a staff charge. You may not lose prepared spells from your school of specialty, if any. The spell slot lost must be equal to or higher in level than the specific spell stored in the staff, including any level-increasing metamagic enhancements. You cannot emulate a charge for a staff function that does not match a specific spell.
