Keep your skin for Kong, once he got an awaken he will got a quest and a new ability and you can be happy. Otherwise. If you dont know about things like "Awaken" or Skin ability, listen to the ohers who tried to clarify things for you. Take a look on Garrick and you will see he has 6 ability. 5th comes with his Awakening quest after lvl90, 6th is the skin one. There is I think 4 skin with no any ability: Sylphi,Kong,Gale,Lucius. Deal with it.
