The store is evil, right? Full of things to tempt you into spending real money. Actually, no, not really. Hop into the store and you can unlock a free chest every 5 minutes. You'll gain some minor equipment shards, experience potions, or maybe some crafting material to increase your equipment options. Alongside that is a crystal item chest. These are only available (for free) once every 24 hours. They're worth logging in for as they're pretty good for offering up crystals. Oftentimes, there are special offers within the store that can be purchased with crystals rather than real money. They're worth doing. You should earn a steady amount of crystals just by playing and completing quests. Packs include things like a large quantity of money, equipment shards and materials. Don't be afraid to use your crystals for this kind of stuff rather than stockpiling them. This is exactly what you should be saving crystals for. Alternatively, crystals are used for restoring your energy or continuing in combat, but this is a waste of such resources. Just wait it out for your energy bar to restore. Don't use crystals on it.
