[Ivara] already had a powerful team damage buff in the form of [Empowered Quiver] ziplines. We now add a subsumed buffing ability to give her even better damage or support potential.

Roar synergizes with several weapons that focus on damage over time procs. [Xata]'s Whisper and Eclipse provide similar benefits but may require specific enemies and tilesets to shine.

Nourish, Smite, and Shock all increase your elemental damage which allows you to replace a few mods on some weapons. They can adversely change your element combinations so be mindful how they combine with your current element mods in your loadout. Nourish is the easiest to use at it doesn't require an augment slot.

[Enemy Radar] helps you and your team to find enemies at an even greater distance. It may be overkill when combined with [Ivara]'s passive and [Animal Instinct] on companions when you are on smaller tile sets.

Arcane [Rage] synergizes with the game plan of the build. It can be replaced with any other arcane to suit your playstyle.
