As of the launch of Forsaken, it has now been confirmed that the variable level drop system the vendors adhered to in Year One has been patched. The changes made to the way vendors reward Guardians efforts, and the way infusions and mods work, means the old system doesn't make a lot of sense. Going forward vendor rewards (from original Year One vendors at least) are capped to about 20 points (currently 581) below maximum light.

Developing and maintaining VendorEngrams was a fun ride, and I'm forever grateful to all the awesome Guardians who helped with research, voted, donated, developed extensions, or simply helped get the word out — you're all amazing.

Below I'm collating a list of other Destiny 2 community projects; check them out and show them the same awesomeness you've show me. If you know of a community project I've missed (I'm sure there is plenty) please let me know and I'll get it added.

Eyes up, Guardian.
