This [Loki] build utilizes Invisibility along with either an armor stripping ability or a damage buff to give a stealth frame offensive potential. Several abilities can be swapped in depending on the type of content you're going against.
Shuriken is chosen because it doesn't scale with the negative range from [Narrow Minded]. Elemental buffs like Nourish, Shock, and Smite work against specific bosses and allow you to save mods on your weapons. Eclipse, Roar, and [Xata]'s Whisper are also decent options even at average power strength.
Radial Disarm and Switch Teleport don't perform very well with low range. Either can be replaced for your subsumed ability. Switch Teleport at least has the option of running [Safeguard Switch].
[Enemy Radar] mods help your team to find enemies. This build is usually focused on LoS combat so you sometimes need to track down stragglers.
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.
