Eclipse, Roar, and [Xata]'s Whisper allow your warframe to push out a lot of damage as long as you build to each ability's strength. We run Eclipse here because [Gara] has a passive that blinds enemies when she stands in areas with strong light sources.

This build also works with Nourish, Smite, and Shock. It even works with hybrid defensive/offensive options like Elemental Ward or Warcry. I would replace [Adaptation], [Rolling Guard], or [Constitution] for any additional augment if you choose augmented element buffs.

[Rolling Guard] protects us in scaling content but it can be replaced with any other survivability mod. The same can be said for [Adaptation] but to a lesser degree.

Arcane Velocity is run primarily because of the [Kuva Nukor] synergy but you can replace it with any other arcane that increases your damage. You can even run something like Arcane Resistance or Arcane Deflection if the enemies are putting out a lot of those procs.
