As you gain experience, you uncover new secrets about the powers of energy, gravity, stars, and other fundamental sources of cosmic power that grant you the ability to channel these forces and manifest potent preternatural powers. At 1st level, you automatically learn the black hole and supernova stellar revelations. At 2nd level and every 2 levels thereafter, you learn an additional stellar revelation. You cannot select the same stellar revelation more than once unless it says otherwise. You can choose any stellar revelations you wish, but if you have more photon revelations than graviton revelations, or vice versa, it is more difficult to become fully attuned in either mode (see Disproportionate Revelations). The list of stellar revelations begins on Stellar Revelations.
Stellar revelations normally note what kind of action they require. If a stellar revelation does not note the kind of action it takes and it modifies some other action (such as an attack or skill check), it can be used as part of that action. If a stellar revelation allows a saving throw to resist its effects, the DC is equal to 10 + half your solarian level + your Charisma modifier. A revelation that says it lasts for 1 round or until you leave the associated mode lasts for whichever of these durations is longer. You can use stellar revelations both in and out of combat, but since you can’t enter a stellar mode outside of battle, any revelation that lasts for 1 round or as long as you’re in a stellar mode lasts only 1 round if you’re not in combat.
