The runic keyword on a power indicates that the power has two possible added benefits, labeled rune of destruction and rune of protection. When a character uses a runic power, he or she chooses one of the two runes, and the power gains the corresponding benefit. When a character chooses a rune in this way, he or she enters the rune state associated with the chosen rune. A character's rune state ends when he or she enters a different rune state, or at the end of the encounter. A runepriest with the Rune Master class feature gains a benefit while in a rune state.
