Any damage you take for the next 6 seconds will be stored. When this ends, you will deal 100% of the damage taken back at your target up to 10,000. In PvP there are diminishing returns on the damage stored as it increases.
When activated, it tracks damage taken from all sources for 6 seconds. After this time, the player attacks their current target for 100% of the damage stored, with a cap of 10,000. Reprisal has significantly increased hit chance. The damage has diminishing returns during player killing.
Self-inflicted damage and typeless damage is also stored, meaning that Shadow Tendrils and Nex's ice prisons are added to Reprisal's damage.
A hit healed by Resonance adds 1 damage to Reprisal.
Unlike Transfigure, a similar ability that stores damage to later heal the user, the player is not bound or stunned when using Reprisal and is free to perform other abilities and actions.
