Well, someone said without a trainer it's not possible to advance in a skill. Why?
Maybe the process to rank up a skill could be done by myself, working working working and doing experience. For example, when you max red way, I can rank up (over the max) using red way using this magic way a lot in different situations (agains an ulber, against a furnace, againts me...). Each time I use this red way, I can advance in skill over the limit. Of course, this will be a very very slow process, wich permits to break the maximum limit.
