Cantrip Learning

You have learned a number of cantrips and so have many people. Play your cards right and many of them could teach you one or two.

• You unlock this feat upon learning your first cantrip beyond your normal limit. You can, with 8 hours of guided practice on a given cantrip, retain the ability to cast that cantrip indefinitely. Your highest level caster class determines your spellcasting ability for that spell: Charisma for bard, sorcerer, or warlock; Wisdom for cleric or druid; or Intelligence for wizard. If you have two equally leveled caster classes upon gaining this feat you may decide which one will be used.  
• If you come across a cantrip in written form, such as a magical spell scroll, a wizard's spellbook, or a Cantrip Guide you might be able to add it to your spell list.
