NOTE: Before you try this out, remember that this is also an experimental build meant to imitate Shadow Stalker's energy orb attacks,mainly his second attack called Omnidirectional Laser Beams.
The Mods:
The rest are beneficial for this build.
I switched [Metal Fiber] for [Sanctuary] to avoid being disrupted while healing a squadmate, the only downside of removing an armor mod is that your sentinel will quickly die in higher levels if you're not cautious. However, it's up to your preference if you're a bit self-centered.
==============
This build is meant to make Helios a non-melee support offensive sentinel without it's signature weapon for the Shadow Stalker build I made.
Extra Notes: I cannot guarantee that this build is effective since it's an experimental build.
