Gunslashes are a weapon category in Phantasy Star Online 2. They are a cross between short swords and handguns.
Gunslashes are a utility weapon that combine the efforts of both Striking attacks and Ranged attacks into a single weapon. They are the only weapon class whose weapons can be equipped by any Class in the game, but are best wielded by Classes that can capitalize on their strengths, such as Hunters.
Gunslashes are typically seen as weak weapons; in exchange for their plethora of Striking and Ranged attacks, they exhibit relatively low ATK stats in comparison to more specialized weapons. In addition, they are not specialized by any class and require boosts from generic skills to increase their damage.
However, Gunslashes are also fairly decent crowd control weapons, with Photon Arts that deal high multi-target ranged and strike damage. In addition, they exhibit fairly high PP recovery rates in relation to their relatively quick rate of attack; in Gun Mode, they have the highest PP recovery of all Ranged weapons.
The Gunslash's Weapon Action is known as Mode Change. By activating your Weapon Action, you can switch between Sword and Gun Modes. This changes the properties of your basic attack; in Sword Mode, a basic combo consists of quick slashes, while in Gun Mode, a basic combo consists of quick shots. The active Mode also changes which attack the Photon Art Strezwei starts with.
