@ChrisPerkinsDnD is there a method to judge the CR of certain creatures that you wish to grant levels as a caster? How would you adjust it?

The DMG offers guidance. If the added spells change the creature's average damage output significantly, there will be a CR bump. #WOTCstaff https://t.co/CUEZ24i5ym
