Blue Crystals are one of the forms of currency in the game. You'll gradually get crystals through completing various activities. You can also buy them with real money and microtransactions. Crystals can be used to buy supplies for repairing items or completing collections. This achievement requires you to spend 400 crystals in total, a hefty number that will take a lot of work to get without buying them with real cash.
