Jaw Breakers Double-Bladed Scimitars (Rare)

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.

Forged as a pair, these magic weapons are crafted from the matching upper and lower jaw bones of a tarrasque. Their innate magic—and one of the reasons the tar-rasque's bite is so powerful—creates an arcanomagnetic pull between the two jawbones, dealing devastating damage to whatever lies between them. You gain a +1 bonus to attack and damage rolls you make with each of these magic weapons. These weapons deal piercing damage instead of their usual damage type.

Chomp: When you engage in two-weapon fighting using these two weapons and hit the same target with both weapons, the attack you make with your second weapon deals an additional 1d8 damage.

Optional Attunement: You can choose to attune to a pair of jaw breakers. They count as a single magic item with regard to the number of magic items you can attune to. When you do so, the weapons gain the Swirling Dervish property while you are attuned to them.

OA: Swirling Dervish: Harnessing the power of the blades, you leap over a target, becoming a tornado of lacerating blades. As an action while you wield both jaw breakers, you can perform a magically-enhanced jump, attacking creatures you pass over. This jump has a maximum distance of 20 feet, is a straight line, must end in an unoccupied space, does not provoke attacks of opportunity, and each foot you clear on the jump costs one foot of movement. You can make one attack against a creature under you in each 5-foot space over which you jump. These attacks always alternate main-hand, then off-hand. For example, if you jumped over one Huge creature, you could make three attacks against it (the second one dealing Chomp's extra damage on a hit). If you jumped over three Medium creatures, you could make one attack against each (with no extra damage from Chomp).

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.
