"Stacks 1 totem whenever you're attacked by a target during the enemy's turn or use a skill during your turn. Becomes able to use the [Volcanic Tribe Totem] skill when you stack 3 totems. Attacks all enemies to remove all beneficial effects and decreases the HP by 5% per harmful effect granted when you use the skill. Up to 10% is applied to the boss."
I assume the effect that decreasess enemy HP by 5% based on their current debuffs is current HP, but not sure. Because if its max HP its usually written explicitly. Does anyone know?
