I was just brainstorming a character that could be kinda funny. I call it The Prestidigitator - a character built to prepare the maximum possible number of cantrips per day. Take a gnome or an elf, both of which can get two cantrips from heritage and ancestry feats, make them a specialist wizard so you can prepare another six cantrips, take a cleric, druid, or sorcerer dedication and then get cantrip expansion with it, get a second dedication, then a third. Either the second or third should be bard and you get inspirational performance (for a composition cantrip) and then esoteric polymath, which I think would let you prepare another cantrip (at least as written). And then get your fourth dedication at 20. You end up with 18 or 19 daily cantrips, all heightened to level 10. Of course you have to prepare prestidigitation every day, because why else would you be playing this character?
