Your mystery provides you with divine magical power. You can cast spells using the Cast a Spell activity, and you can supply material, somatic, and verbal components when casting spells. Your unconventional access to this divine power means you can usually replace material components with somatic components, so you don't need to use a material component pouch when casting spells.
At 1st level, you can cast up to two 1st-level spells per day. You must know spells to cast them, and you learn them via the spell repertoire class feature. The number of spells you can cast each day is called your spell slots. As you increase in level as an oracle, your number of spells per day increases, as does the highest level of spells you can cast, as shown here:
| Your Level | Cantrips | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th | 10th |

Some of your spells require you to attempt a spell attack roll to see how effective they are, or have your enemies roll against your spell DC (typically by attempting a saving throw). Since your key ability is Charisma, your spell attack rolls and spell DCs use your Charisma modifier.
Heightening Spells
When you get spell slots of 2nd level and higher, you can fill those slots with stronger versions of lower-level spells. To cast a heightened spell, you must have the heightened version in your repertoire; for example, you can't cast a 3rd-level version of a spell that is only in your repertoire at 1st level. Many spells have specific improvements when they are heightened to certain levels. The signature spells class feature lets you heighten certain spells freely.
Spell Repertoire
The collection of spells you can cast is called your spell repertoire. At 1st level, you learn two 1st-level spells of your choice and five cantrips of your choice. You choose these from the common spells from the divine spell list, or from other divine spells to which you have access. You can cast any spell in your spell repertoire by using a spell slot of an appropriate spell level.
You add to this spell repertoire as you increase in level. Each time you get a spell slot (see Table 2–3), you add a spell of the same level to your spell repertoire. At 2nd level, you select another 1st-level spell; at 3rd level, you select two 2nd-level spells, and so on. When you add spells, you might add a higher-level version of a spell you already have, so you can cast a heightened version of that spell.
Though you gain them at the same rate, your spell slots and the spells in your spell repertoire are separate. If a feat or other ability adds a spell to your spell repertoire, it wouldn't give you another spell slot, and vice versa.
Swapping Spells In Your Repertoire
As you gain new spells in your repertoire, you might want to replace some of the spells you previously learned. This can be useful for retraining spells once you've learned them at a higher level. Each time you gain a level and learn new spells, you can swap out one of your old spells for a different spell of the same level. You can also instead swap a cantrip. You can also swap out spells by retraining during downtime.
