Peddler's Bargain (HB)

You touch up to three coins and turn them into deadly projectiles that can be flicked with lethal velocity against your foes. For the duration, you can flick one transmuted coin as a ranged spell attack with a range of 30 feet as part of the casting of this spell. You can make a single attack using a transmuted coin as part of casting this spell. On subsequent turns, you can flick a transmuted coin by using a Bonus Action. Only you can make attacks using the coins, though other creatures can safely handle them without discharging the spell. At the end of the battle, you can recover half your hurled coins of each type by taking a minute to search the battlefield. Different coins create different effects when used to make attacks, as presented below:

Copper. On a hit, the coin deals 1d6 Piercing damage plus your spellcasting ability modifier.

Silver. On a hit, the coin deals 1d8 Piercing damage plus your spellcasting ability modifier ignoring Resistance to Piercing damage.

Gold. On a hit, the coin deals 1d10 Piercing damage plus your spellcasting ability modifier ignoring Resistance and Immunity to Piercing damage.

Platinum. On a hit, the coin deals 1d12 Piercing damage plus your spellcasting ability modifier ignoring Resistance and Immunity to Piercing damage and can score a Critical Hit on a roll of 15-20.

Using a Higher-Level Spell Slot: You can enchant one more coin for each spell slot level above 1.
