Bloodshed Double-Bladed Scimitar

The hilt of this sword bears a carnelian engraved with the blood rune.

You can add your Constitution modifier (minimum of +1) to the damage rolls of attacks made with this weapon.

Invoking the Rune: When you target a creature with an attack using this weapon, you can invoke the sword's rune, causing it to flare with crimson light and infusing your attack with bloodthirsty precision. You then spend and roll one of your unspent Hit Dice and add the number rolled to the attack roll. You can choose to invoke the rune after rolling the d20.

If this attack hits, you can also spend and roll any number of your unspent Hit Dice and add the total rolled to the weapon's damage.

Once the rune has been invoked, it can't be invoked again until the next dawn.

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.
