[Ivara]'s base kit has many augments that synergize together to make [Artemis Bow] a powerful albeit small nuke. We run a few of them together on this build to allow [Ivara] to tackle various types of content by just swapping out augments.
Ensnare allows the [Concentrated Arrow] to nuke large groups of enemies while they're kept crowd controlled and stationary. Roar is a strong bonus when paired with the forced Slash procs from [Hunter Munitions] or [Internal Bleeding]. [Primed Fulmination] can be used on the [Artemis Bow] which allows you to use Navigator and all base abilities rather than relying on a subsumed ability for crowd control or damage.
Concentrated Arrow provides a small-room sized nuke to deal with most enemies outside of long endurance runs. We run high range since it has no damage fall-off.
[Empowered Quiver] is a great damage bonus even at average ability strength. It can be replaced if you don't want to camp on ziplines or need to fit in another augment.
Survivability shouldn't be needed if you're constantly in Prowl. On smaller maps you may still be hit by AoE attacks from enemies so you can replace [Overextended] with [Rolling Guard].
[Growing Power] is easy to proc and this build runs low enough Strength that it feels impactful when combined with all the different abilities that it benefits.
Arcane [Rage] synergizes with the game plan of the build. It can be replaced but there aren't many other options other than survivability focused arcanes.
