You can cleave any foe within your reach.
Prerequisites
Benefit
Whenever you use Great Cleave or Whirlwind Cleave and miss an attack, you can expend one use of mythic power to continue making attacks against foes within your reach. A miss still counts as an attack assigned to a creature, so you can’t attack that creature again (unless you have Whirlwind Cleave and have attacked all creatures).
You can use this feat multiple times in a single cleave attack, but you must expend one additional use of mythic power to continue the attack each time you miss.
