General use build for end-game Diriga. Synth-Deconstruct works pretty well with Arc-Coil.
First we have to put Arc-Coil on the first slot, to prioritize it to use for Diriga, before Assult-Mode. Every 1-2 sec if there's an enemy within range Arc-Coil deals him 100 dmg (up to 7 targets), so Synth-Deconstruct will activate.
Due to more health orbs that we have from enemies, we can use Synth-Fiber and Metal-Fiber to protect our Sentinel.
I had tested few weapons with this build, but the most reliable is Helstrum. It's built for viral-radiation stat-proc, so it provides nice crowd control BUT the most important mods are Firestorm and fire-rate. (it helps to damage much more enemies around, so Synth-Deconstruct becomes more reliable). I have noticed I got the most orbs using Helstrum, rather than Artax or Verglas.
