Coin Gun

The Coin Gun is a Hardmode ranged weapon that uses coins as ammunition, which cannot be retrieved once fired. Its damage and velocity depend on the type of coin fired. It is dropped very rarely (0.0125% or 1/8000 chance) by Pirate Invasion enemies, excluding the Parrot. The drop rate for the Pirate Captain is quadrupled (0.05% or 1/2000) and quintupled again with the Flying Dutchman (0.25% or 1/400).

The Coin Gun cannot receive any modifiers that increase damage, so the modifier that boosts its the most is Agile (+12% speed, +3% critical strike chance). Zealous (+5% critical strike chance) serves as the most ammo-efficient option, dealing the greatest amount of damage per coin fired.

Tips

 * If used with Platinum Coins, the Coin Gun is easily one of the most powerful weapons, though it can make combat prohibitively expensive.
 * Just using Copper Coins is more efficient in terms of total damage over number of projectiles.
 * Combining the Greedy Ring or Lucky Coin with the Coin Gun can establish a somewhat infinite supply of ammo, as long as combat is intensive.
 * The Coin Gun becomes much more viable in due to the larger volume of coin drops.
 * It pairs well with Vortex armor or Shroomite armor as it greatly increases the and reduces coins used.
 * The Coin Gun requires a constant craft of 100 low-tier coins because the pickup of coins can convert the stacks with lower than 100 coins into a higher-tier coin, otherwise it can eventually use unwanted coins. It requires constant attention to the ammunition amount indicated. If there is less than 200 ammo, it can start using Silver, Gold or Platinum Coins.

Trivia

 * The Coin Gun is extremely rare. Before 1.3, it took an average of 66-67 Pirate Invasions completed before it dropped. With the addition of the Flying Dutchman in 1.3, there is an increased chance of the weapon drop, but it is still very rare.
