Skill Points

Description
A Skill Point is basically the embodiment of ones potential, it's almost like a chain if you will, a soul becomes a potential and a potential because that of which can be applied to ones self. Essentially it is the physical embodiment of ones soul and how they apply that, mainly in order to gain more abilities through harnessing ones soul power, once you have learn't it there's no going back in any normal means so chose wisely what you invest in. But at the same time, "Do not regret what you have done," as you cannot change it.

How to Obtain
You can attain a Skill Points (or SP as the community commonly refers to it) through gaining a soul, aka potential. So you might be wondering, can someone lose a skill point like losing a soul? The answer is yes, but you do not regress on that of which you have already learned through the normal means of losing a soul. You simply have a skill point taken away and do not lose the any skills previously learned, it only makes progressing harder if you are not only max. You can also have a negative amount of skill points since each skill learned those skill points will be consumed as well, having negative skill points does not effect you, it only makes progressing harder.

Uses
As you could have guessed by now, skill points are, quite obviously, used to gain skills and abilities from various trainers/mystical objects for a skill line (these objects being mark crystals). Early within your game life you will mainly only be getting these skills from trainers that of which are scattered throughout the games map. Buying a skill only consumes a skill point and no longer costs any Yen, upon purchase of a skill you will be down by the amount of skill points used to purchase the skill in the first place. So once you have enough skill points for a desired skill do not wait get it as soon as possible.

Most Important Note
YOU ONLY HAVE 4 SKILL SLOTS USABLE, so it's heavily advised you carefully plot ahead of time for what build you would like to achieve.
