Steel Path Endurance Build: Replaced 4th ability with Pillage for armor/shield strip, requires two casts for full strip. Arcane [Guardian] is required, 2nd arcane you could swap in anything you want, I swap in Arcanes for the build based on how I want to play..ex. Molt Augmented, Arcane Strike, Arcane Energize, etc.
You can swap out [Power Drift] with [Handspring] or Primed Surefooted, I find that while invisible with Prowl and on a zipline I don't get knocked down, So im running Power Drift to increase armor strip for pillage.
Between Pillage, Prowl, Navigator/[Empowered Quiver] you can take out any high level enemies. Archon shards can further increase survivability, I personally have two Azure (blue) shards for +300 armor, two Crimson (red) shards +20 power strength to increase shield strip with Pillage, one Amber (orange) shard with casting speed to speed up pillage, prowl cast. Hope the build works for you guys, this also scales perfectly in Steel Path Duviri Circuit. Enjoy!
