Warding Rune (Su): At 6th level, when a creature is damaged by your blast rune, it cannot attack you for a number of rounds equal to 1/2 your cleric level unless it succeeds at a Will save, as per the spell sanctuary. Using this ability is an immediate action when a creature triggers one of your blast runes. The ability does not prevent you from being attacked or affected by area of effect spells or abilities. You can use this ability once per day at 8th level, plus one additional time per day at 14th level and 20th level.
