Become enraged, staggering and dealing 150% heartrune damage to targets within 3m. Then turning into a hulking beast for 10s. While active, light attacks deal 100% damage and your heavy attack is a leap, dealing 120% damage and knocking down targets. Use the heartrune again to end it, dealing 150% damage within 3m. Heartrunes under GS700 can be upgraded at a Stonecutting station.
