Acidic Bowstring

When this bowstring is attached to any longbow, your ranged melee attacks made with the weapon deal an additional 1d4 acid damage. You may only gain this benefit once per round. This damage is increased based on your level. 6th level (2d4). 12th level (3d4). 18th level (4d4). Putting this bowstring on a longbow requires a short rest to apply. When you roll a natural 1 as an attack roll with this bowstring equipped, you take the acid damage doubled. Attacks made with the weapon this item is attached to are considered magical.

Notes: Damage: Acid
