Hi MasterofCoin, when you use amulets that are transmitted by link, the members of the group receive 10% of the percentage that you already receive. This 10% does not carry over if you are already wearing an amulet of that type. For example: You get together with some friends and the 4 activate amulets of the same type, then the 4 receive the same as they would if they were not in the link.
