Journeyman Wizards
Each of the Arcane Schools is a unique entity and should be celebrated as such. However¸ there isn't any monsters to help with low level specialist in their field. These wizards can be used in any world in any setting and are recommended to be used as apprentices of stronger wizards in their school of choice or a recent graduate striking it on their own. These wizards are also a great low level option to allow your party wizard to claim their spell book into their own after combat
