Hoard Your Exotic Engrams
It might be tempting to decrypt all your Exotic engrams once you get them, but I recommend holding off on doing that until you’re above the 360 threshold. By decrypting them at a lower light level, the levels on your Exotics will be significantly lower than what they could be if you were to decrypt them at 365.
While you can always infuse your higher level blue gear into the Exotics, this is a waste of resources, and will require you to have multiple Exotic Shards on hand as well. If you keep them until you reach 365, your Exotic engrams should give you higher level stuff that you can choose to either equip or infuse into your existing weapons. Don’t forget to pop your Three of Coins before each Strike boss too, as that will increase your chances of getting an Exotic drop from them.
