As you know, in most (or all) classic RPGs, there is no way to reassign your levels or skills. You must plan your character well, or reload. Here, as the game is still in development and new skills are being introduced, I added a relatively simple mechanic to be able to, ocassionally, replace your skills for new ones and try them out. That doesn't mean it has to be convenient or cheap, as it's not intended as a way to replace skills "for a day". I am not sure if I will make it more flexible or not in the future, but at this point I won't be adding a skill selection UI, moreso when betatesters only have to spend 1 gold.
