Being a Guardian isn't easy as it comes with plenty of stress. When things get overwhelming, many Guardians break out their engram stress balls. Just ask Cayde-6! Each package of Destiny Engram Stress Balls contains one engram stress ball available in green, yellow, blue, and purple. The engrams are printed with designs to match their in-game appearance. You can't unlock one for weapons and gear, but you at least can squeeze it until you're stress-free. One chosen at random.
