Inventory
Save your gems, the game's premium currency, to unlock more inventory slots. Do not waste gems on rare chests, since you will be upgrading your own equipment at the forge.
Jewels
Jewels can be slotted into empty sockets on equipment to gain various bonuses. You can combine jewels to power up a single jewel. You must spend gold each time you want to insert or remove a jewel. The price increases with the rarity of the jewel. You can sell unwanted jewels for gold. After a jewel reaches its maximum level, you can evolve it if you have the proper materials, which will then permanently increase its bonus stats. Also consider waiting for special events where fusions will have a guaranteed bonus.
Mastery Points and gems
When you complete a level for the first time, you will earn one Mastery Point and five gems as a reward. You can repeat that level four more times, leveling up your mastery for that specific level up to a maximum of five Mastery Points. Once you reach that maximum number you will also receive fifty gems.
Party bonus
