       "description": "While unleashing Ultimate, the powers of the Demonblade boost the wielder's Total DMG by 10.0% for 15s, during which the wielder is also cursed by the Demonblade and loses 1% of her max HP per second (will not cause death). The 2nd hit of Bloodefrye Frenzy releases the powers of the Demonblade in the form of flames, and for every 1% of the wielder's HP loss, this hit additionally deals 80% ATK of Fire DMG (max stacks: 10). The wielder stops losing Hp after unleashing the 2nd hit."
