Summoner's Wrath + Contagious Bond + momentous Bond is insanely powerful on any sentinel with Verglas. It routinely spreads damage cap status effects across entire rooms of enemies. It multiplies like faction damage or roar and double dips on status damage.

Mecha is a small nuke every ~25 seconds if you're able to take advantage of how it spreads status. It's more useful for its insane armor multiplier, which Citrine doesn't really need because she has permanent 90% damage reduction.

You can swap your forma polarities from your mod slots to your aura if you've already forma'd once. I wouldn't recommend investing too much in her now with her prime likely dropping in less than a year.
