ToV PS3 - Patty Fleur: Artes

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

Skill Henka Majutsu (スキル変化魔術 - "Altered Magic Artes")
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 and artes obtained from costumes, the altered version will be learned as a separate arte, which no longer requires the skills to be equipped.

Burst Artes (バーストアーツ)
Burst Artes can be activated only while Over Limit mode is active. The burst arte duration, damage, and effects are increased with Over Limit levels, with maximum effects at Level 3. Similar to altered artes, burst artes can be "altered" if the correct skills are equipped. However, these elemental burst artes cannot be learned separately. All burst artes are activated by holding the during any arcane or altered arte.
