However....An air ele could use conjure lightning on an air staff or wand and use Jude's Insight on top of that.
THIS BIT IS JUST A THEORY AND MIGHT NOT WORK......Also could be good when using Thunderclap as you dont really want to use spells with Thunderclap due to the energy drain. Thunderclap only works when someone is hit by lightning. Judges Insight turns damage into holly damage so this is just a theory. NOT TESTED
NOTE: Conjure Lightning MUST be cast BEFORE Judges Insight as Conjure Lightning removes all enchaments. Thunderclap is a Hex so that doesn't matter.
