- If a skill has no base Cast Time or modifiers reduce it to 0 or less, the casting phase is skipped entirely, and no cast bar appears. - During casting, the character cannot move, attack, or use other skills, but consumables can still be used. If the character takes damage during casting, the skill is canceled unless special conditions apply (e.g., using a Phen or being Devotion by a Crusader).
Casting Bar
The Casting Bar (or "Cast Bar" or CB) is shown as a progress gauge above the character's head. It starts as an empty black bar and gradually fills green as casting progresses. Once the bar is full, the casting is complete. Some skills may not display a Cast Bar, even though they have a cast time (e.g., Sight or Quagmire).
