Pennypuncher Slingshot

This slingshot requires two hands to attack and is adorned with coin-like designs. You gain a +1 bonus to attack and damage rolls made with this magic weapon. In addition, when you make a ranged attack with this weapon and use a coin as its ammunition, it deals extra damage on a hit based on the value of the coin you use:

Pennypuncher Slingshot:

Recovering coins fired in this way follows the normal rules for recovering ammunition. Depending on the nature of the battlefield, you may recover more or fewer coins than normal as determined by the GM.

Ammunition: You can use a weapon that has the ammunition property to make a ranged attack only if you have ammunition to fire from the weapon. Each time you attack with the weapon, you expend one piece of ammunition. The ammunition of a firearm is destroyed upon use. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon). At the end of the battle, you can recover half your expended ammunition by taking a minute to search the battlefield. If you use a weapon that has the ammunition property to make a melee attack, you treat the weapon as an improvised weapon (see "Improvised Weapons"). A sling must be loaded to deal any damage when used in this way.

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.
