Dou Qi Methods and Dou Qi Techniques
Dou Qi Method is like a foundation for you as a Dou Zhe. It is like your internal energy skill. You can only possess one Dou Qi Method at a time and you at least have to be a Dou Zhe. If you want a new Dou Qi Method then you will have to abandon your current Dou Qi Method and you will have to train the new method from the beginning. This is why it is very important which Dou Qi Method you choose.
A Dou Qi Method gives your Dou Qi an Attribute, or element. Without a Dou Qi Method, a person's Dou Qi would be described as white, or colorless. Learning a Dou Qi Method gives color to a person's Dou Qi. For example, low Huang level fire attribute Dou Qi Methods make Dou Qi a pale yellow color. The higher the rank of the method, the deeper the color.
Yellow (Huang): This is the first rank skill class and within each skill there is a further subclass as low/mid/high.
Black (Xuan)
Earth (Di)
Heaven (Tian)

Dou Qi techniques is separated into 4 classes. The higher the level, the stronger the skill. Once you have reached Dou Practitioner, you are able to learn skills and abilities. Reading scrolls is the most common way to gain a new skill; however, there are other ways to obtain abilities. You can even develop new and unique abilities through rigorous training. Though uncommon, these are abilities that have never been seen before and are unique to you.
