We're planning to start the Booster Pack promotion around the 3rd June. The Booster Pack will give you current and reserve stamina and also increase your maximum stamina and inventory (backpack) slots. It will also give some items designed to help new players such as a 3 piece Legendary Set (level 5) and 5 potions (giving Adept Learner, Librarian and Animal Magnetism level 150 for 120 minutes).
Once the promotion starts, we'll let you know which sites it is available on so you can get a promo code. Note we've added a new section in the 'Upgrades' menu called 'Redeem' which you can use to redeem promo codes
