Tsunami, helps with trash clear and good for vet/elite, falls kinda off tho
Tempest, damage boost, put the skill on Wind Devils
Wraith, just 2 nodes to get the flat lightning damage
Viper & Widow for resist reduction
Spear of Heavens might be okayish, haven’t tried that one cuz it costs too much to get there imo and I’d rather have that proc chance on attack, not being attacked
The rest is up to you. I think flat lightning damage and attack speed is most important because of Stormcaller’s Pact and I’d also run with pure lightning based weapons. Getting flat and % health through devotions is also a good idea because of how Wendigo Totem works.
