In this week’s This Week at Bungie, the studio revealed how the economy of Destiny 2 will change when the Forsaken expansion is released on Sept. 4. Reputation tokens will, for the most part, be going away in favor of destination materials, like Dusklight Shards from the European Dead Zone.

Players have long wondered what will happen to their various currencies when the expansion is released. Bungie clarified that players will still be able to redeem any tokens they currently have, with the exception of Ikora Rey’s meditation tokens. However, most of these tokens will no longer drop from from challenges or Public Events. Activities that used to reward tokens will now offer players planetary materials instead.
