Ok as I dont know if this is possible but who cares ill suggest this i have a crap load of spirit and i believe a lot of others has a lot also. I think we should be able to change some spirit to some exp or epic coins make the farming that everyone has to do for levels worth the grinding we are doing cause atm i have no books to learn and have about 86 mil spirit i think we should make a way to change this spirit and make it useful instead of sitting there.
Learn all sage or demon skills than report back how much spirit u have left.
