Stormblast Mine throws a mine that deals lightning damage in an area around it when detonated. The mines have an aura which causes enemies in the aura to take increased damage.

Skill functions and interactions

• The innate aura effect of this skill (Each Mine applies 3% increased Damage Taken to Enemies near it, up to a maximum of 150%) has a base radius distance of 35 units and are scaled by modifiers to area, including those specific to auras. Increased aura effect will improve the bonus per mine near an enemy, but will not affect the maximum bonus.
  • This modifier applies globally, and can be used to increase damage taken by other skills by maximizing the mine duration without detonating it.
