Those are Orpheus’ specializations in the elements.
Fire: Precise: Orpheus’ movements are unusually precise (for his low fire score). He’s delicate and careful. This would be useful for things like sewing, origami, and maybe lockpicking. Not so meaningful in a fight.
Orpheus gets a +1 to his Fire whenever precision of movement is important.
Air: Calm: Orpheus is eternally calm and levelheaded. Almost serene. He almost never raises his voice, and is very rarely angry. Even in the middle of a chaotic situation, Orpheus stays calm.
Orpheus gets a +1 to his Air to stay calm and level headed in emotional or chaotic situations.
Water: Empathy: Orpheus is relatively good at understanding people’s emotions (for his low water score). He’s generally personable, or at least isn’t likely to commit a faux pas.
Orpheus gets a +1 to his Water to read other’s emotions.
Earth: Stone Hard: Orpheus is made of rock. Even his high earth score doesn’t do his near immunity to damage justice.
Orpheus gets a +1 to his Earth whenever his body’s hardness would matter. For example, when taking blunt damage.
