Fanmade Cursed Tools

Gunner’s Spare Change

item (coins), Legendary

A gold coin engraved with a styalized version of the word "Sharpshooter" on one side, and the head of an Eagle on the opposite side. When you attack with a gun that shoots a single projectile, you can chose to flip this coin into the air. When this coin is flicked into the air, you make a slight of hand check DC = to the opponent's AC - your Charisma bonus. On a success the bullet hits the coin, bounces off of it, and hits the target, treating it as if you dealt max damage, and on a fail your attack misses and the coin simply lands on the ground before returning back to you. If you roll within your criticl hit range while using this, the shot is treated as a critical hit and deals critical damage and acts as if you rolled the max amount of damage possible. If you have multiple coins you can throw up to 4 coins in the air, each coil lessening the slight of hand DC by your Charisma bonus and increasing your critical hit range per coin. This coin always returns to you immediately after it stops falling, but does not do this if you simply hand the coins to somebody or if the coins are taken from you. Only 4 of these coins have ever been made supposedly. You have to wait a turn before you can use a coin again.
