While you never graduated, you're still a Wizard at heart. You gain the following benefits:

• You are considered a wizard for any feat or magic item that has a prerequisite of a wizard. If anything in the item or feat's description references wizard spells or abilities, work with the DM to adapt it to your sorcerer abilities.
• You gain the Bonfire Cantrip as your "Favorite Cantrip". You can now upcast this catrip using any available spell slots. When you do, the spell gains 1d8 of damage for each level of spell slot used, and the radius of the spell grows an additional 5 feet. At 10th level you gain a second cantrip that will function similarly.
• if you have the Wild Magic subclass, you trigger a Wild Magic Surge whenever you cast a spell.
