Cycle
Source Player Core pg. 144
Actions with the cycle trait change your current stellar attunement to its opposite state. When you take such an action with this trait, you benefit from the additional effect of your current attunement if the action had the attuned trait, but once you complete the action, your attunement changes to its counterpart (so graviton-attuned if you were photonattuned before taking the action, or vice versa).
