If you're looking for a build that is easy to use, a lot of fun, and stomps normal Star Chart through Sortie missions, this is where it's at. Tons of range to apply Sow, lots of power strength to then nuke it all with Reap, a little sprint speed so you can get around quickly, some efficiency and energy replenish so you can spam abilities to your heart's content. What more could you want?
Note: Arcanes and Molt aren't necessary, by any means. And if you want to try out other abilities via Helminth, go have a blast. I enjoy using [Firewalker] for move speed and status immunity, Breach Surge for more damage, Fire Blast if I want armor strip, or Ensnare if CC would be helpful. Experiment and find out what fits your playstyle the best.
If you're looking for something to use in Steel Path, check out my Steel Path Destroyer Sevagoth build or Release The Kraken build.
You shouldn't even need to go into your Exalted Shadow, but if you just want to and need a build for that, here you go and here's a build for the claws.
