Shadow Steel Double-Bladed Scimitar

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.

Another deadly invention, but not by gnomes, Shadow Steel is said to require souls to be produced. According to rumors, the souls are torn into pieces using dark spells and transformed into a raw spiritual essence of pain, which takes a pitch-black sheen reflecting no light. Weapons made from it cannot be resisted by conventional metals. They cut through the spiritual essence of living flesh, discharging excruciating pain into the victim. The rare survivors of these weapons report levels of pain that can render a person inert for hours. When wielding a weapon made of Shadow Steel, you have advantage on attack rolls made against any target wearing medium or heavy armor. A creature hit by a Shadow Steel Blade must make a DC 14 Constitution saving throw, becoming stunned until the end of its next turn on a failed save.

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.
