This page describes Amy's Battle Style in each of the games in which she appeared.
Soulcalibur III[]
Amy's greatest advantage is her swift mobility. She also has a selection of fast attacks, both high and low, which can be used to escape a tight situation. An example of this is her Graceful Cutter, a quick sweeping low attack. In addition to her quick moves, Amy has many moves that can link into moderately damaging combos.
Amy's attack damage is by far her greatest disadvantage as a character and is noticeable by anyone trying to master her. Like Talim, Amy mainly relies on combos to inflict any decent and notable damage. Another liability for her that her moves can be easily predicted.
In general, Amy is very quick but her attack power is very low. It is best to remain in mid-range so as to set up a combo. This style is available to custom Pirates (Level 10+) and Knights (Level 20+) under the Rapier discipline.
