The most important division is race- characters in Frontier are divided into Humans, Monsters, Mystics, and Mecs. Whenever a weapon or ability is used, there is a chance that the statistics that type of attack uses will raise. Humans may use Sword, Gun, and Bare Handed abilities, as well as spells. Swords have a wide variety of attacks. Whenever you use a sword attack, there is a chance a light bulb will appear above the characters head, and a new sword technique will be learned.
Specific techniques have a greater chance of teaching certain other techniques.
As well, there are specific techniques that may only be learned while using Katana-type swords. Bare Handed attacks are weaker than sword attacks, but have a powerful secret technique that is more powerful than any other in the game. They are learned in much the same way as sword techniques, but are divided loosely among punch, kick, slide, and throw attacks. Using a punch attack will make learning another punch attack more likely, etc. Gun attacks can become very powerful, and are relatively easy to master.
