Dueling Swords of Farron

The Dueling Swords of Farron are a dagger and a longsword, meant to be wielded simultaneously. Attuning to either weapon requires attuning to both weapons - you cannot attune to only one of them; as such, it requires two attunement slots to attune to these weapons.

While attuned to the Dueling Swords of Farron, you gain proficiency in the Acrobatics skill. If you are already proficient in Acrobatics, you add double your proficiency bonus instead.

Farron Sweep

While attuned to the Dueling Swords of Farron and wielding one in each hand, as an action, you can make a special attack with these weapons called the Farron Sweep. When you perform the Farron Sweep, you may move up to 10 feet (this does not consume movement speed) and may traverse enemy spaces during this movement, then make a single attack with the Farron Longsword against all creatures of your choice within 5 feet of you. After performing the Farron Sweep, you may make a single attack with the Farron Dagger as a bonus action.

Farron Dagger

Dagger, Legendary, requires attunement by a creature proficient in martial weapons

This dagger receives a +2 bonus to attack and damage rolls.

If you are attuned to the Farron Dagger, as a reaction to a creature making a melee weapon attack against you, you may make an attack against that creature with the Farron Dagger. If this attack hits, that creature’s attack fails, but if your attack fails, that creature's attack automatically hits.

Farron Longsword

Longsword, Legendary, requries attunement by a creature proficient in martial weapons

This longsword receives a +2 bonus to attack and damage rolls, does not have the versatile property, and has the finesse property.

Whenever you take the attack action while wielding the Farron Longsword, if you are also wielding the Farron Dagger, you can replace one of those attacks with an Acrobatics check opposed by a target creature’s Insight check. That creature must be of Large size or smaller and must be within 5 feet of you. If you succeed, you may move up to 10 feet and may traverse that creature’s space during this movement, and your next attack against that creature this turn has advantage.

Lore

Players must discover this information through research, or use the Legend Lore spell to learn this item’s lore.

The Legion of Farron was a famed, and ultimately infamous, order of knights tasked with a single duty: to guard against the Abyss, and any vile creature or corruption that might arise from it. For centuries, the Abyss Watchers, as they were called, stood vigilant against the Abyss and fought bravely to prevent its malignant influence from permeating across the material plane. Where they started as guards, however, they became fanatics, hunting down even the slightest signs of the Abyss with increasing ruthlessness and violence, until the appearance of their uniforms in a region became known as an ill omen - for where they ventured, death surely followed.

But the creatures of the Abyss are cunning and shrewd, and the closeness of the Watchers to the Abyss they so watched made them especially susceptible to its corruptive influence. The Watchers knew of this, and though they hunted down corrupted knights within their own ranks as fervently as they hunted down signs of the Abyss elsewhere, ultimately, the corruption spread so deep that the Legion consumed itself from within, culminating in a massive battle between their brothers and sisters in arms so devastating that it all but annihilated the order itself, and the Legion of Farron was disbanded and left to the pages of history.

The Dueling Swords of Farron were bestowed upon the most honored of their knights, emphasizing their rapid and aggressive fighting style that shunned the use of a shield in favor of a fast and brutal offense. Though few such sword pairs still exist today (even fewer found together), almost all of them having been lost to time, it is said that the souls of the renowned knights who fought with the Dueling Swords live on in their weapons, imbuing their skill and unique fighting style to those who can attune to their enchanted blades.
