Chew through the enemy with this vicious automatic hand shotgun.
The Pyrana is an automatic Tenno pistol shotgun, available from the Tenno Lab. With its fast fire rate and its physical damage leaning towards Slash damage, the Pyrana can easily decimate groups of lightly armored targets or the Infested. However, this is counter-balanced by its small magazine and long reload time.
Barrel Diffusion can greatly increase the amount of pellets per shot (a fully ranked Barrel Diffusion can yield up to 26 pellets per shot). Although it can be paired with Lethal Torrent for more pellets, it will increase your rate of fire tremendously and deplete your ammo very quickly.
However, the net result is 33-34 pellets, the highest out of ANY shotgun. Coupled with its high crit chance, it can be a very deadly close-quarters weapon.
The weapon's name, design and description are all derived from the piranha, an omnivorous freshwater fish that inhabits South American rivers. The piranha is well known for hunting its prey in packs and viciously tearing it apart.
