Let's face it, the gun might as well have no perks. Zen Moment is a waste when its catalyst is +30 Stability, its Exotic trait actively encourages to be inaccurate and, as far as I can tell, it's the only Exotic gun (i.e. not including Bows or Swords) to not have a Grip or Stock. It is genuinely just a 150 Scout, already one of the most unforgiving archetypes in the game, that wants you to miss on purpose and its only slightly redeeming feature is good stats versus other 150s.
I genuinely think it's in the same tier as Salvation's Grip, and it was almost criminal for it to not be buffed alongside the likes of Lumina and Tarrabah with this expansion.

Jade is a green scout. That being said, it's a green scout that's better than most legendaries of it's archetype.
