During the Forsaken-era of Destiny 2 (Year 2), Bungie re-introduced random rolls on weapons going forward. That means that weapons that you find out in the wild come with random perks and traits that modify that weapon’s performance beyond its base stats. This allows players to explore a variety of weapon perk combinations and adds diversity to the loot pool.
