Arc

Arc is a lightning spell that creates a chaining pulse of electricity.

Skill functions and interactions

  • Chain: Arc deals 15% more damage per remaining chain. Arc gains base chains from gem level, and additional sources of chain such as Chain Support are also taken into account for this bonus.

    • Every time Arc chains, a secondary Arc is created that hits an additional nearby enemy. This secondary Arc cannot chain further.

    • Arc remembers the last two enemies hit by the main Arc, and will not hit these enemies again. This means at least 3 enemies are required before the main Arc can hit the same enemy twice.
