Skins

Skins increase hero stats and change their appearance. Each hero has a Default skin that boosts their main characteristic: strength, agility, or intelligence. Additional skins upgrade secondary stats. To level up a skin, you need to use Skin Stones.

Note
All skin bonuses stack no matter what skin is active at the moment. Equipping a skin only changes the appearance of a hero.

You can purchase skins with Skin Stones, buy them in the Skin Sale tab, or get them during special events. 

You can upgrade some skins even further, boosting their bonus by 100%. Such an upgrade is called Skin+. To level up a Skin+, you need to use Skin Stones.

You can distinguish a Skin+ from regular skins by a plus sign next to its name and a golden frame.

You can get a Skin+ only during special events. Developers may add other ways of getting these upgrades in the future.

Note
To get a certain Skin+, you need to have both a hero and an original skin. If you do not have the respective hero or skin, the button in the event shop will remain inactive.

For example, to get Mushy and Shroom's Lunar Skin+ you need to have Mushy and Shroom and their Lunar skin.
