With today's server save, we have implemented a balancing change in anticipation of the winter update, which, among many other things, will conclude the Iksupan adventure. If you have not yet started the questline around "Galthen and the City of Gold", the following adjustment may come in handy for you: the XP from iks chuka has been increased by 16%, and the XP from iks pututu by 31%.
