Variant: Cantrip Versatility

At 1st level, you may choose to record your cantrips in your spellbook, instead of simply knowing them. If you do so, you begin play by adding 4 cantrips to your spellbook from the Wizard spell list. You must prepare your cantrips in order to cast them, just as your other spells; however, these do not count against your usual spell preparation limit. Instead, you may prepare a number of cantrips equal to your proficiency bonus.

Adding a new cantrip to your spellbook takes 1 hour, and costs 25 gp. The cost represents the material components you expend as you experiment with the cantrip to master it, as well as the fine inks you need to record it. Once you have spent this time and money, you can prepare the cantrip just like your other cantrips.
