Hey guys, just posting the cost to level rare skins (from 1 to 6). These skins are changing the TOP 10 in the game (along Beck downgrade ), so this info may be useful for planning to get them.
As far as I checked, these status (common armor, elemental armor and health) and their bonus doesnt change for Common Skins. For instance, check Hardscope Deputy and Commando skins.
