The trident has a swing cooldown of roughly 1.5 seconds. It takes six hits to knock an opponent down. The user will then have to stomp twice due to its difficulty hitting enemies who are knocked down.
The trident has a shorter range than the spear. It's a shorter spear that deals less damage but has a shorter swing cooldown. Take advantage of its range by maintaining a range that is outside of the enemy's swing distance but close enough for your own weapon.
