Diablo III: Reaper of Souls

Your electrocute will continue to bounce until it has used up all of its bounces. This means electrocute will always hit the maximum amount of times between 2+ mobs. However, mobs will take reduced damage for every additional hit they take and the reduction is actually quite drastic.

So it'd synergize really well with the chain lightning rune then.
Do the hits trigger proc effects?
