Blackstaff

Created by the renowned archmage Khelben Arunsun and shared only with those whom he trusts implicitly, Blackstaff has three principle effects.

First, the spell gives the affected staff or quarterstaff a +4 enhancement bonus on attack and damage rolls.

Second, any creature struck by a successful melee or touch attack with the Blackstaff is subject to a Dispel Magic effect. The effect works exactly like a targeted Dispel Magic spell cast by the creator of the Blackstaff.

Third, any spellcaster struck by a successful melee or touch attack with the Blackstaff loses one unused spell slot of the highest level available. A successful WIS save negates the loss, but not any damage or the dispel effects.

Blackstaff may be cast upon any nonmagical quarterstaff or on a magical staff in the caster's possession. If cast on a magical staff, the wielder of the staff must decide as a free action on their turn each round whether they will use the staff's normal abilities or the effects of the Blackstaff spell. Nothing prevents the caster from giving a staff or quarterstaff under the effect of a Blackstaff spell to another creature to wield after casting the spell.
