Mystic Artes

Hi-Oujis are the hidden techniques that certain characters in the Tales series can use. They don't appear in every game and they can only be performed under certain circumstances. Other names for the hi-ougi include the Secret Tech, the Mystic Arte and the Blast Calibur.

In Tales of the Abyss
In this game, Mystic Artes or Hi-Ougis can only be performed when the character using them is in a state of Over-Limit. The player must then launch an Arcane Arte or a high-level Fonic Arte whilst holding down the X button. When the character's attack ends, he or she will immediately go into a Mystic Arte.

In Tales of the Tempest
Even though there are no actual Hi-Ougis in this game, there is still a type of special attack that can only be used under certain circumstances. Two of the main characters can transform into beasts called Ramourne after killing enough enemies and when they do their attack power is greatly heightened. Their form lasts either until they run out of TP or until the battle ends.
