Arcane Staff

Spells you can normally cast may be placed into a prepared quarterstaff. You can store a number of spell levels equal to your caster level, but no spell can be higher than 2nd level. For example, a 5th-level caster could store two 2nd-level spells and a 1st-level spell; or one 2nd-level spell and three 1st-level spell; or any other combination totaling five levels. 0-level spells cannot be stored within an arcane staff. A spell stored within the quarterstaff can be cast just as any other spell. It does not count against your normal allotment of spells for a given day. You use up any applicable material components to cast the spell when you store it in the staff. You cannot have more than one prepared arcane staff at any given time.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can store spells of the spell slot level used to cast this spell -1. So if this spell was cast with a 4th level spell slot, you could store up to 3rd level spells, to a maxium of 6th level using a 7th level spell slot.
