Dodge is an action for avoiding bullets or arrows. You can move quickly short distance.
However be careful with its cool time!

Player gain invulnerable frames while doing Dodge. Except some damage type, players don't take damage completely. The invulnerable duration is quite short so it may be difficult to utilize it well, but it possibly saves your life when surrounded by enemies?
