The Elemental Shaman 2T15 bonus triggers from Lightning Bolt and Chain Lightning hits (including Overloads). A Chain Lightning that hits 5 targets has 5 separate chances to trigger the Lightning Strike. If it Overloads, then 10 chances. There is no ICD, so it can proc multiple times from a single Chain Lightning. However, in the next build (or perhaps a hotfix), the damage from the Lightning Strike will be split between affected targets. There is a very high potential impact from this set bonus, so we’re keeping our eye on this, and may have to nerf it. But we’re trying it this way, since it is the most fun version.
I am so happy for this. Will crit become more effective and how would we put this in rotationwise? I haven't played in awhile but I might come back because of this.
