Staff of the Magi question
Long time listener, first time caller. I'm playing a really fun gnome wizard character that just recently acquired the Staff of the Magi in a long trek through the Shadowfell and some light grave robbery.
Wizard is level 10 and only has access to 5th level spell slots. Some of the staff's charged spells are cast at level 7. Can the wizard cast those using the staff or should he continue to cast Fireball and Lightning Bolt as prepared spells until reaching a higher level? Plane Shift is also in there.
EDIT: Thanks everyone! Being able to remove Fireball and Lightning Bolt (and others) from my prepared list is awesome, really opens up a LOT of possibilities. Plus, this character is very chaotic so having this staff is going to be very fun for him.
