Double-Bladed Scimitar of Retribution

The double scimitar is the signature weapon of Valenar elves. A haft of fine wood supports a long blade on either end. Forged with techniques honed over tens of thousands of years, these blades are strong, sharp, and remarkably light. Each scimitar is a masterpiece, and as a result the double scimitar is an expensive weapon, but few people ever have an opportunity to purchase one. If you're an elf, your blade could have a long and storied history. If you're not an elf, you might have stolen the weapon from a fallen foe or received it from a dying Valenar ally. If you work with your DM to create the story behind your double scimitar, you can start with the weapon at 1st level in place of a martial weapon normally granted by your class. However, it can be dangerous for a non-elf to carry a double scimitar. Valenar may demand its return or challenge you to prove that you're worthy to wield it.

You gain a +3 bonus to attack and damage rolls made with this sword. Hit points lost to this weapon's damage can be regained only through a short or long rest, rather than by regeneration, magic, or any other means.

Curse: You're unwilling to part with this weapon while attuned to it. While attuned to this weapon, you also have disadvantage on attack rolls made with weapons other than this one. The vengeful spirit possessing the sword shares its history and lust for vengeance with the wielder. After each successful long rest, you experience nightmares of the spirit's past, culminating in its death. When you wake, you must make a DC 11 Constitution saving throw. On a failed save, you only gain the benefits of a short rest. Only the Remove Curse spell allows you to end attunement to this item.

Corrupting: This item corrupts. See the "Infernal Item Corruption" section.

Special: If you attack with a double-bladed scimitar as part of the Attack action on your turn, you can use a bonus action immediately after to make a melee attack with it. This attack deals 1d4 slashing damage on a hit, instead of 2d4.

Two-Handed: This weapon requires two hands when you attack with it.
