There are six main skills grade each divided in low, mid, high and top. Some skills can evolve and as they do, they gain a star. Ex: MC's Iron Fist
- Basics (The fundamentals. Most people train in them in the beginning just to strengthen their bodies until they become Rank 4 Martial Disciples and can start training in Mortal Grade techniques at which time they give up training the basics. The system made mc train for three full years in various types of basics skill until they were printed in his bones. This has allowed him to get deep and solid foundations. Thanks to that, each breakthrough gives him a huge boost in his fighting power and there's basically no bottleneck in his training);
- Mortal grade (Merely a set of basic moves and stances put together. They're just like karate, taekwondo and other skills. Difference is that they use spirit energy. The higher the rank, the more intricate and powerful they are and also the more spirit energy they require)
- Earth Grade (use spirit energy to launch a martial art which can create a spirit manifestation as they hold a few truths. Only martial scholars and above can train in them as their body is strong enough and they glimpse in the truth of the world)
- Heaven grade (Use the inner spirit energy to command the surrounding spiritual energy to launch a martial art. The might is such that the weakest of these martial arts can level a normal mountain and destroy the bodies and spirits of anyone lower than the scholar stage in a few kilometres around even before being fully released. That's why there's an unwritten rule which says that Martial Kings and above must fight in the air since one gains the ability to fly upon becoming a Prince stage expert and gaining entry level understanding in concepts)
- Sage grade (Using the world principles as base, one can launch a martial capable of reversing the world's principles for a few moments and destroying heaven and earth)
- Divine (Can only be used (forcibly) by some people who have fully understood a low level law as they use and affect the very laws that built and rule the world. Basically, only Late Martial Saints can have use them, peak mid Saints (Level 6 Saints) being able to forcibly launch them)
