I'm playing in a Age of Ashes campaign. When my sorcerer went to 5th level, the system allows me to know add three spells to my repertoire, but only allows me to cast one per day. My workaround is to just not mark off the 3rd level spell slot until I've used my third spell, but it means I have to write it down and remember if we break a session in the middle of day. Is there something I'm missing here?
