Adamantine Bow (5e Equipment)
From D&D Wiki
Weapon (longbow), artifact (requires attunement)
Standing at 2’ 4” tall, this adamantine bow is a masterpiece of craftsmanship capable of tearing apart those it hits.
Powerful Recurve. The weapon's normal range is 250 feet and its long range is 1000 feet instead of the ranges normal for a longbow. In addition, when you miss an attack roll with the Adamantine Bow, you may reroll the attack roll. You may use this feature a number of times equal to your Dexterity modifier, and you regain all expended uses after a long rest.
Close-Range Combat. The Adamantine Bow can be used as a Simple melee weapon with the Two-Handed and Finesse properties. On a hit, it deals 1d8 Bludgeoning damage. This applies even while the Adamantine Bow is in its compact form, and melee attacks made with this bow still count as magical for the sake of overcoming resistances and immunities.
