Gold coins could be used to buy all kinds of avatars, avatars, guard (eye) skins, some hero skins, and some hero skins.
Of course, allowing players to use gold coins to buy a portion of the hero skins was equivalent to letting the players have a discount. It had to be strictly controlled, otherwise, it would cause the entire economic system to collapse.
Gold coins could only buy a small number of average-quality skins. The specific list of available skins would change every week, and the corresponding hero's proficiency must reach the highest Grandmaster level to buy, and the price was extremely high.
As for the skin color, it was just a change of color, and it wasn't hard to make, so Chen Mo made it in the first version.
After a player obtained a certain skin, they could spend a certain amount of point certificates and gold coins to buy a dazzling skin.
Other than that, players could also use gold coins to open chests.
