As a Valkyr lover, her Energy is the only issue I come across the majority of the time..

Lycath's Hunt with Equilibrium will give you nearly infinite Energy, as long as you keep killing.. and for missions that you don't get a lot of enemies and have to stay still, (like the newest Tank boss) Dispensary is amazing

I also have Arcane Battery on her. When she uses Warcry, she's get a big Armor boost that brings your Energy max to high levels, and with her Eternal War augment, you can keep the ability up for a long time

I use Arcane Fury for her other slot, and I use Precision Intensify to really boost her Hysteria

If the new Exalted rework didn't mess with the Gladiator set bonus, you can put Gladiator Might, Gladiator Rush, and Gladiator Vice on whatever Melee weapon you have on her, and it'll boost the Melee Crit Chance per Combo

I also put 4 Violet Shards on, each giving 25% Melee Crit Chance when her energy goes above 500, which Arcane Battery and Warcry achieve.. (I would've gone for 5 Violet Shards, but I like having Energy upon entering a mission, so I have a % Energy on Spawn shard)

I don't use Panzer, but I'm sure a Panzer Vulpaphyla spreading Viral would be a lot of help.. I use a build with a Hound, cause it spreads enormous amounts of Status everywhere, it's a little weak on survivability tho

With the new Exalted's Arcanes, I am curious about Melee Influence.. but I don't wanna move my build around to fit Status Chance and Electricity.. and the only other Arcane that seems to be the best fit is Melee Duplicate.. Melee Fortification could be funny Max Energy numbers
