Altered Artes are activated in place of their original arte during battle, if the required skills are equipped. After the original arte has been used more than 100 times (or more than 50 times for magic artes), the altered version will be learned as a separate arte, which no longer requires the skills to be equipped. In the PS3 demo version, all available altered artes are learned separately by default, and the required skills are unavailable. Additional altered artes cannot be activated.
