Probably one of the harder warframes to farm because a blueprint is on a Rotation C mission. If you see her as a reward for the Duviri Circuit it can save you a lot of bad RNG trying to get her Neuroptics from a Survival mission.
Her abilities make most difficult missions doable even while solo, and my favourite use for her is to use Mallet to quickly spawn a Sister of Parvos. Her kit is pretty versatile giving mild CC, damage, invisibility, and even energy regeneration which can also be granted from Octavia Specters.
