Dragonwing Scimitars (Patreon)

Weapon (scimitar), legendary (requires attunement)

This pair of twin scimitars features draconic guards and winglike blades. Despite there being two weapons, they are considered to be a single item for the purposes of attuning to them. While holding one of the swords, you always know the general direction and distance of the other.

Chromatic Change. Each of the swords is associated with a damage type: either acid, cold, fire, lightning or poison. Any target hit by one of the scimitars takes an extra 1d10 damage of its associated type. While one of them is in your hand, you can use a bonus action to change its damage type to a different one. When you do, the color of its metal changes to reflect the new damage type.

Draconic Riposte. While holding each of the swords in either hand, you can use your reaction when you're hit by a melee attack to gain a +4 bonus to your AC against the triggering attack, potentially causing it to miss you. If the attack misses as a result of this reaction and the attacker is within 5 feet of you, you can immediately make an opportunity attack against the attacker using one of the scimitars.

Winged Rush. While you're holding the two swords in either hand, you gain a flying speed equal to your walking speed whenever you take the Dash action. You lose this speed at the end of your turn, falling if you are in the air and nothing else is holding you aloft.

The half-dragon drew her twinned blades as her adversary approached. Flames licked from the edge of the first, and sparks leaped from the second. The colors echoed her red scales and blue regalia.

With a maniacal grin, her forked tongue couldn't help but flick the air as she cackled, "This has been a long time coming. Come at me!"
