Destiny 2 has launched to a very positive reception so far, especially among fans of the original game (primarily because developer Bungie fixed many of Destiny’s most glaring issues for the sequel). But one change that Bungie made has left players fuming: In Destiny 2, armor shaders are single-use consumable items.

Shaders are cosmetic items that can be applied to armor to give it a color scheme that’s different from its original look. In the original Destiny, players often received shaders as loot drops from various activities. They could also buy shaders from vendors such as Eva Levante with an in-game currency called Glimmer. (In both Destiny and Destiny 2, Glimmer must be earned through play — you can’t buy it with real money.)
