Status warfare doesn't come up too much in GFL too much given bosses are routinely immune to it and elites get shortened status effect durations, but if you actually need status effects from an AR, the stun is surprisingly far-reaching behind the initial target, and she prioritizes enemies suffering from debuffs.

Calico and Thunder's lovechild. Also kinda slutty because French. Boasts a weird AoE attack that, amazingly, stuns stuff. The stun is better if there's multiple targets in the AoE, but worse vs. a single target. The damage isn't great (6x multiplier + not super high FP) but you mostly want the stun and the damage is a bonus.

Note that the stun's effective area is actually not as wide as a normal stun grenade because it's a narrow vertical strip rather than a normal radius. Also, it won't stun anything a regular flashbang won't already stun.
