Master Arcanum

A book... well, most of one. It floats, though!

The Master Arcanum grants to a wizard who wields it the ability to cast any wizard spell without preparation, so long as the wizard is able to cast spells of that particular level. It also functions as a wizard's arcane focus, removing the need for common material components when casting a spell.

Only one hand is needed to utilize the Master Arcanum (it floats, sure, but you still need a hand to flip through its pages).

The current possessor of the Master Arcanum is Zaszir Zolando, a human wizard working under Mr. Black. The Master Arcanum is currently missing its cantrips section as well.
