You have around 38,320,568 combinations. At first I thought "wow, this isn't much customization." Something about the items on the table read as "alchemy" to me and not "put these in the slots". It didn't take me long though, and once I figured out what they all did, I had a bunch of fun customizing this guy. I see a lot of potential for this game where maybe you have to deduce the abilities of an enemy wizard based on their appearance. I'm sure you already have tons of ideas.
TLDR, great job, and amazing art.
