Arbor Warden's flowers bloom when the Barrinade Ability is active, and also while in Social zones or the Inspection Screen. The flowers bloom in colors based on your current subclass
I had the pleasure of helping add a little sparkle accent to the Arbor Warden Exotic Titan Armor, debuting with Destiny 2: Season of the Deep. I was responsible for the shader and reveal tech that hides the flowers when the ability is not active. I worked closely with Alex Jackson on Character Art in order to ship, and I hope it's something Titan players enjoy!
