[Inaros] has a lackluster base kit so most builds after the introduction of the Helminth system will focus on the new ability. This build dumps everything into range and survivability and uses a subsumed ability that fits into the stat distribution.
Ensnare is chosen because it's the most versatile CC ability but Larva and Resonator can also work in this build albeit with slightly less effectiveness.
Sandstorm is replaced because it's a horrible ability but any of the others can be put on the chopping block depending on the content that you're going against.
[Enemy Radar] mods help us to find enemies. Due to the nature of the build we need to sometimes seek out stragglers.
Arcane Grace and Arcane [Guardian] help to increase your survivability in all content. They can be replaced with offensive arcanes if you're planning on going to the level cap as everything will be instantly killing you at that point anyway.
