Infinite damage loop with Choir of the Storm

Choir of the Storm Jade Amulet currently can enable an infinite damage loop.

The skill Greater Lightning Bolt that it grants is not counted as meta-activated, and thus it is able to generate Energy for meta skillgems.

So, you can have meta skillgems triggering damage skills that on crit trigger Greater Lightning Bolt, which in turn generates Energy for mega skillgems, completing the loop, which goes on infinitely, as long as spells have valid target(s).
