Wizarding Styles
There are three common archetypes of Wizards:
1. Old, wizened Wizards with a lot of experience under their belt. Generally tend to use a variety of spells for different situations, rather than trying to brute force with a couple powerful spells.
2. The young prodigy. Similar to the old wizard, but much more limited in their knowledge. Have a few trick aces up their sleeves, but often end up using the few spells they do know in creative or unexpected ways to solve problems
3. The grunt. These are the most limited in the variety of their spell usage, and often use only a couple favored spells. Instead of using their spells in unconventional ways like the prodigy, they use the raw power of their spells to brute force problems.
I have also seen a ‘Tank’ or ‘Muscle’ type of Wizard that surrounds them self in magic like a suit of armor, or that uses their magic to amplify their physical capability. Think Gaara or Rock Lee from Naruto respectively. I consider this to be a subtype of the ‘Grunt’ Wizards.
For an example of the differences between these types of Wizards: If there is a locked door, the wizened Wizard might use a spell to unlock the door. A prodigy wizard might try to concentrate fire magic to remove the hinges from the door. The grunt will likely go “f-- this” and try to blow down the door outright.
