Players can get variants of this weapon with random rolls by completing other deliveries too. However, there are also rewards for reaching certain milestones. Less often, players will also get the chance to receive mods, Enhancement Cores, or non-powerful legendary items. These are usually blue items or perhaps some tokens. The RewardsEach batch of cookies delivered will grant players a reward.
The bad news is you will lose the common and rare ingredients. If you gift these cookies to the Cryptarch, he will trade them for 15 Essence, so at least you don't have to go back and complete more activities. These don't count for any of the rewards, but all is not lost if you accidentally mess up a recipe and create these instead. Any other combination of ingredients will create Burned Edge Transit cookies.
