While no new weapon systems are coming in Destiny 2: Forsaken, the studio is seriously overhauling the Masterwork and mod setups from the base game. > All weapons will now have Masterwork levels, up to tier 10. Each time the level is raised, the weapon’s Masterwork stat will go up by a single tier. The first few levels are relatively cheap to increase, only taking a handful of Glimmer. However, to reach tier 10, players will need to invest Legendary Shards and Masterwork Cores into their weapons.
