Dashing while attacking can yield many different results. You can dash forward, sideways and even backward while attacking. Each direction you dash and attack in results in a completely different attack. There are two distinct dashing ranged attacks: rapid shot and charged shot. These are affected by the direction you choose to dash in before firing.
Continuous Fire Dash Shot: Except for club weapons, every weapon has some form of dashing continuous fire. Each weapon type has special properties for this attack. Some weapons fire shots that home in better on targets than others. Other weapons may fire more shots while dashing forward.
Charged Dash Shot: These attacks are among the most damaging ranged abilities at your disposal and have a wide variety of special properties. Some weapons gain enhanced elemental damage properties during a forward dash. Other Charged Dash Shots may act as a powerful area-of-effect attack.
For melee combat, there is only the forward dash attack. The range and effectiveness of the forward dash melee attack varies between weapon types. However, it is possible to use this attack outside of its normal range. While dashing at an opponent, flick the Circle Pad in the opposite direction and press the L button. Be aware that you must wait a few moments before you can perform this attack again outside of melee range.
