Main Mechanics in Arc Elementalist Lightning Caster build

  • Chaining: Arc is a lightning-based spell with the ability to chain between monsters.
    Each time it chains, it will also split to a second nearby enemy from where it can't chain further. The amount of times Arc can chain depends on its gem level and can be increased by enchantments, with a maximum of 10 chains attainable with this build. 
  • Shock: An elemental status ailment which increases the damage an enemy takes by up to 50% for a duration, based on our lightning damage dealt within a single hit. Arc comes with an implicit 10% chance to shock, which we further amplify and back up through shock effect to assure consistently strong shocks on all targets.
  • Semi-Crit: Instead of going all out on crit, we just get some to proc Elemental Overload, a conditional buff which gives us a 40% more damage multiplier if we've crit in the past 8 seconds.
  • Mind over Matter: This is a Keystone which redirects 30% of damage we take to our mana pool, as long as we have sufficient mana. In order for this to be effective, we need an unreserved mana pool equal to approx. 43% of our life pool and a quick way to refill mana, which we gain through regeneration and optional leech.
