This is my long-running build on my [Ivara Prime]. Great for stealth and utility. Bring some energy pads for the beginning of the mission, and you can take out a whole spy mission, scan everyone while they're unaware for Simaris, avoid all of the traps, and get extra energy etc. from locked containers.
Shooting Gallery makes this so much better, too. If you want to quickly go from spy node to spy node without sneaking and rolling the whole way, just throw up your 2 and dash between everyone.
I mainly use this as perma-invisibility. I use the 2 (Shooting Gallery) a fair bit, and occasionally a dash wire or cloak arrow. I pretty much never pull out her bow.
Another great thing to take along for spy/scan missions with this build is a [Carrier Prime] with '[Looter]' attached, so your sentinel will constantly burst containers around you as you go. Leave '[Assault Mode]' at home. And make sure to take Primed Animal Instinct. It stacks on top of Loot Detector, Thief's Wit, and her passive Enemy Radar.
