Staff Expertise [Epic]
[Epic Insights; Epic Level Magic by Andy Collins; Wizards Archive - 03/14/2003]
You can activate staffs with the speed that an archer fires arrows.
Prerequisites: Craft Staff, Master Staff, Quicken Spell, Spellcraft 30 ranks.
Benefits: You may activate a staff in place of an attack instead of as a standard action. As a full-round action, you could thus make as many staff activations as you could normally make ranged attacks. For instance, if your base attack bonus is +11, you could activate a staff three times as a full-round action. If you also had the Rapid Shot feat, you could activate the staff four times as a full-round action.
Each activation after the first costs one additional charge from the staff, cumulative. Thus, the second activation in a round costs 2 extra charges, the third activation 3 extra charges, and so forth.
