This is a no-forma build good right out of the foundry with no primed mods.

For my current forma'd Ivara build with Primed mods, go here:

This is a no-forma no-primed version of 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. I mainly use this as perma-invisibility.

Another great thing to take along for spy/scan missions with this build is a carrier / [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 [Animal Instinct]. It stacks on top of [Loot Detector] and her passive [Enemy Radar].
