So what should you purchase? The simple answer is "the items you'll need in the future". If you think that's too vague consider it this way: How do you typically earn more rewards? Through skilling, fighting, or even questing? Are you a fan of melee and ranged attack or maybe you're a Mage? Find items with OSRS Accounts that give you the most benefits and are also reasonably priced.
