i try and made a ticket to oasis team they say to ask in forums cuz they are to lazy to fix the game or answer to our problems, also the translation in english about skills or what to do with some items *s cuz is not in detail or not a good translation at all. But from what the description says they must be exchanged for skill books like 1 skill page= 1 skill book but i cant find where to use them to exchange them cuz on champs dose not work and i cant see any other place to use them so yeah broken game with noob ppl who dont invest in it to make it better for those who give them money and support the game.
