Caustic Weapon

Prerequisite: 3rd level Alchemist, a simple or martial weapon

When you infuse this weapon, pick one of the following damage types: Acid or Poison. When the wielder hits a creature with this weapon, it deals an additional 1d4 of the chosen damage type. This magic weapon also has a number of charges equal to 1 + your Intelligence modifier (minimum of 1). When the wielder hits a creature with this weapon, it can expend a charge to force the target to make a Constitution saving throw against your spell save DC. On a failed save, the target takes 1d4 of the chosen damage type at the start of its next turn. The weapon regains all expended charges daily at dawn.
