You can click your gear to preview the Set system.
Just collect 4 gears in the same prefix can activate the set. For example, Dragon Bow, Dragon Tally, Dragon Helmet, Dragon Armor will be automatically combined to a set.And your gears will turn to bling bling after you collected it. At the same time, you will receive the attribute of the set, which will upgrade your ATK, HP, etc.
