Adamantine Double-Bladed Scimitar

Whenever you hit an object with this weapon, the hit is a critical hit.

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.

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.
