Critical Strike is a special ability found on many different weapons. It gives the pirate a low chance to deal double damage with an attack (Skill or Combo) with that weapon. This is assuming that the pirate has managed to hit their enemy with a superior blow or a more precise hit to cause greater damage. Some Cannon Items grant the ability of performing a critical strike with a specific ammo type. Unlike regular attacks where the damage appears in red, the Critical Strike appears in bigger yellow numbers with an exclamation point at the end. Critical Strike is a passive weapon skill, and does not need to be activated, happens at random.
This skill can be very useful to get the upper hand in PvP battles and boss battles.
