From the Pathfinder SRD's description of the third-party Wan oracle curse from Oracle’s Curse (emphasis mine):
You are pale, sickly, and languorous, with one foot in death’s door.
You have the fatigued condition, but are immune to the exhausted condition.
At 5th level, you learn the “inflict” spell of any level spell you can cast.
At 10th level, add ray of exhaustion to your spells known.
At 15th level, add waves of exhaustion to your spells known.
I was skimming through the oracle curses list on the Pathfinder SRD and found the curse quoted above. I'm confused by the wording.
Is there a spell called "inflict" that I'm not aware of, or is it a method of delivery? Maybe it's referring to inflict light wounds and inflict moderate wounds. That's my best guess, but I'm likely wrong on that.
