Big shout-out to the ocs and lore that depicts physical/appearance changes due to high concentration and uses of magic btw that shit is so cool. Whether your wizard's hair turns blue or straight up grows an extra arm due to the excessive amount of powerful magic they use everyday I eat that shit up. Bonus points if it's a rare/newly discovered condition or if your wizard is just straight up unrecognizable from arc 1 to arc 4. Bonus bonus points if the wizard gains a disability from it and has to learn to adapt to their new condition
