Items that acquire heat will no longer automatically level up when enough heat is required at the end of a level. Instead, a new type of item called ‘Fire Crystals’ must be used within a new interface called ‘The Forge’ in order to level up your items.
The Forge can be accessed in town or at any arsenal station. When an item is ready to level up, open the Forge and select the item. The item will require a certain number of a specific fire crystal to level up. However, in some cases there is a chance the forge will not succeed and the fire crystals will be lost. No heat is ever lost due a failed forging.
Additionally, players have the option to add more than the requisite fire crystals in order to improve the odds of a successful forge as well as the chance to gain a special bonus.
Fire crystals may be purchased in stacks in the Supply Depot, acquired via missions or found as loot in treasure blocks.
