FP, short for Fighting Points or Fatigue Points, is one of the three basic forms of energy a character has. Some skills cost a certain amount of FP to use, making it important for skill users to keep their FP as full as possible. FP can be restored with VitalDrinks.
Players have a maximum value for their FP. This value is a proportional STA. Some classes have a lower FP to STA ratio than others. A player's maximum FP be raised by buffs and awakened or statted equipment.
