Piranha Gun

The Piranha Gun is a post-Plantera Hardmode ranged weapon that fires a single piranha-shaped projectile that latches onto an enemy to do continuous damage while the attack button is being held. The projectile must return to the gun before being fired again, but if the attack button is held and other enemies are still within range, it will proceed to automatically home in on those enemies without needing to return, and attack until all enemies in range are defeated, or the attack button is released. The Piranha Gun is found in the Dungeon's Jungle Chest, which requires the Jungle Key to open. This weapon is very effective to most strong enemies.

Its best modifier is Unreal.

Tips

 * The Piranha Gun is great for eliminating swarms of enemies as you can hide behind walls whilst it jumps around between enemies in a wide open space, thus eliminating everything in a room from the safety of your point.
 * Especially good for eliminating Paladins as a player can safely fire at them then hide behind a wall whilst the piranha does its work.
 * This weapon is useful in dispatching teleporting enemies, such as Necromancers, since the piranha will lock on to and follow the target each teleport.
 * Useful in stunlocking enemies; certain enemies and bosses, or boss segments such as the Golem's fist, can not attack or fire whilst being damaged, thus, the Piranha Gun nullifies their attacks.
 * Some users may find the Piranha Gun is useful for support. It can be easily used to constantly damage bosses without focusing on aiming projectiles or going in close for melee attacks, allowing the user to focus on dodging the attacks of the boss and to hold out for any debuffs to clear such as Potion Sickness.
 * The Piranha Gun can be effective against Dungeon Guardians.

Trivia

 * A possible reference to a weapon used by the character Vector from Despicable Me.
 * The gun itself is actually a highly modified flail.
