Pathfinder: Wrath of the Righteous · Mythic ability: damage
Elemental Barrage
A target damaged by one energy type can take added divine damage when hit with a different energy type within three rounds.
How it works
When a spell deals energy damage to a creature, that creature is marked. If a spell dealing a different energy type hits the marked target during the next three rounds, it takes additional divine damage equal to 1d6 per mythic rank. The guide explicitly limits the effect to spells and says it does not work with elemental properties applied to a melee weapon.
