Lightning Rod is an ele trait that causes damage and weakness whenever you hit a mob with a hard cc attack. Mordrem Menders are unsteady, meaning they can suffer a minor knockback whenever they get hit. It turns out that knocking a mob back due to unsteady counts as you hitting them with a cc and procs lightning rod. Lightning rod does damage itself and so it can also knock them back, proccing another lightning rod. The result? Instant death, sometimes.
