I am thinking of a prestige system for the lvl 100 people.
When you prestige you will get a little token and there will be a little board that you can spend it on like the skills, the max prestige will be 10 and when you prestige you will start from lvl 1 again, each prestige will show everyone by the color of your diamond thing,
blue- non prestige
yellow prestige 1
green-prestige 2
pink-prestige 3
red-prestige 4
purple-prestige 5
orange -prestige 6
dark blue-prestige 7
dark red-prestige 8
white-prestige 9
black-prestige 10

With these prestige thinks i think you should unlock either shaman items- or skills to help you at shamaning

I haven't thought of any yet but leave your idea
