1st level magic user. Plenty of fun as is, however, I've been thinking about a way to let starting wizards make temporary magic items. How's this...
1. cast a Nystul's magic aura on an object, lasts 1 day/level
2. cast a Find Familiar (doesn't count against the 'once a year' stipulation). Casting time is 1-24 hours. The familiar is bound to the object with the aura on it.
3. cast whatever spell you want the object to store or use after that.
It will have as many charges as the caster's intelligence-level (diminishing returns)
