ToV - Rita Mordio: Artes

Altered Artes (スキル変化技 - Skill Henkawaza)
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, the altered version will be learned as a separate arte, which no longer requires the skills to be equipped.

Altered Magic Artes (スキル変化魔術 - Skill Henka Majutsu)
Altered Magic Artes are activated in place of their original arte during battle, if the required skills are equipped. After the original spell has been used more than 50 times, the altered version will be learned as a separate arte, which no longer requires the skills to be equipped.
