Hearthstone's economy has two currencies, gold and dust. Gold is easy. You earn it by fulfilling quests, plus a bonus ten for every three wins, and a hundred of it buys you a card pack. With a new quest available each day, it's quite possible to build a decent collection without spending much real world money.

Dust is more complex. You use it to make cards of your choice, rather than the blind luck of opening a pack. There's only one reliable way to get it, and that's by disenchanting existing cards you own. Since you can only have two of each card in a deck, you need something to do with the extras you collect. But it's still in short supply compared to gold.

How best to get it, and how best to spend it, is what we're going to explain in this guide.
