Wyvern Knights are renowned for the Pierce skill that they possess, allowing them to bypass the enemy's Defense when activated, in turn resulting in each attack inflicting a sizeable amount of damage. Pierce can be stacked with a Critical hit, a fact that further amplifies the strength of each attack by a devastating amount.
A well-known glitch is associated with the Pierce skill, however; this glitch causes the game to freeze, and occurs as a result of its user activating Pierce on the first hit but failing to kill the enemy and thereafter attacking a second time without the enemy retaliating. This glitch does not occur when battle animations are turned off or in the original Japanese release.
The Triangle Attack, originally a move that can only be performed by a set of three Pegasus-based characters, can still be performed with Wyvern Knights, but only if the player has one Wyvern Knight and two Pegasus or Falcon Knights, alongside a requisite for the Wyvern Knight character to initiate the attack.
