Most/All of the epic destiny melee attacks are acting as cleaves, unsure if this is intentional.
Epic Destiny abilities that act as cleaves.
Boulder's Might
Draw Them Out
Celestial Mandate
The Flower's Thorn
Smite the Wicked
Draw them out also requires a target for some reason, making it very annoying to use. Celestial Mandate has no such requirement to be used.
