Some of your spells are cantrips. A cantrip is a special type of spell that doesn't use spell slots. You can cast a cantrip at will, any number of times per day. A cantrip is automatically heightened to half your level rounded up—this is usually equal to the highest level of oracle spell slot you have. For example, as a 1st-level psychic, your cantrips are 1st-level spells, and as a 5th-level psychic, your cantrips are 3rd-level spells.
