Okay first skins can be bought with robux or a coin method. With the robux it will be 10-50 robux since it will just be a skin and will not make it better. It will be like evolutive version for example
If you get a wood sword, it will look like a slim and dumb looking sword, but as you level it up it looks cooler. And the final version will be a outstanding cool giant blade, for the pickaxes the same,
The armor will have the same, with evolutive states and same as above
also skins won’t affect damage but will make you visible if your enemy even cares for you
yesssss
