Valdia uses a stats system to effect what skills you can practice and what activities you can participate in etc. The skills you can practice and the things you can do are dictated by the Stats system, for example mining a certain ore may require more Strength than a previous ore etc. When you first join Valdia you can put your stat points into whatever stat you wish and you can get more stat points by practicing skills and working towards your overall level. When your overall level goes up you gain a certain number of stat points. This still needs expanded on but it is a basic example.
The stats are as follows:
Effects amount you can Carry.
Effects time to complete a job.
Effects movement time from one location to another.
Effects time until next botcheck.
Effects your ability to study books and do more intellectual activities.
