Fulminator

Fulminator

This sword electrifies the entire battlefield. Any lightning damage you deal can turn enemies into conduits that in turn deal damage to nearby foes over several seconds. Individual hits thus spark a contagious chain reaction that spreads rapidly, especially through dense packs.

The sword carries no class restriction, but it naturally comes into its own in any build that commits to lightning damage. Practical tip: aim preferentially at large clusters so as many enemies as possible become conduits at once and their damage areas overlap. The tighter the enemies are packed, the more devastating the arcing damage becomes, and you'll clear whole rooms almost on their own.
