More optimized build for high duration, so you can AFK more easily. Duration isn't maxed, or nearly as high as my other build, but this is far more useable as it has nearly 3x the max energy and better range.
For Aura, I would recommend using an Aura Forma so you'd have some flexibility between [Brief Respite] and [Corrosive Projection], amongst other mods. However, if you don't have any, its entirely preference between [Brief Respite] and [Corrosive Projection] (don't quote me on this, I'm only like 90% sure).
For Arcanes, Arcane Energize is definitely necessary if you don't have Zenurik, but if you do, use Arcane [Fury], or whichever other mod you find suitable. I use Molt Efficiency over Arcane [Fury] here as this build is not meant for you to actively farm whipclaw stacks.
Note that this isn't meant for Steel Path, and I'm relatively sure you'd get killed instantly if you used it there.
