Maxing DPS
Thundering Tempest slows the mob and does over 1k damage per bolt (seems to be 2 hits/sec), auto-aim, and can move while dealing damage! Its range is decent, radius cannot be increased by items however, don’t think it is consider an AOE, although it does AOE. It is great for soloing Terminal Daily.
Lightning Column is among the best for single target DPS. It is a single tile AOE with lingering duration, it absolutely demolishes stationary enemies. While raining down lightning columns, throw in a few Ball of Lightning.
Ball of Light has very good AOE damage, usually hits a single target 2-3 times.
Of course all these damage are boosted by Crashing Hail.
