This exquisite double bladed scimitar was crafted from a rare metal known as Stormsteel, which is said to have been imbued with the power of lightning by the gods themselves. The blades are adorned with intricate runes that seem to glow with a soft blue light, and their edges shimmer like the surface of a pond on a windy day.

Thunderstrike: Once per day, the wielder can call down a bolt of lightning from the sky to strike a single target. The target must make a Dexterity saving throw (DC 23) or take 10d10 lightning damage. If the target succeeds on the saving throw, they take half damage.

Wind Dance: The wielder gains incredible agility and speed, allowing them to move with blinding speed and strike their enemies with a flurry of deadly blows. When wielding the Windcaller's Blades, the wielder gains a +5 bonus to Dexterity and can make one additional attack per round.

Stormcaller: When the wielder is in a location with inclement weather (such as a thunderstorm or hurricane), the Windcaller's Blades become even more deadly. The blades are charged with the power of the storm, allowing the wielder to deal an extra 2d10 lightning damage with each successful hit.

Tempest's Fury: When the wielder is surrounded by enemies, they can unleash a devastating whirlwind attack that deals damage to all enemies within a 10-foot radius. The wielder must make a melee attack roll against each target in the area, and each target takes 4d10 slashing damage on a hit. The wielder takes no damage from this ability. This ability can only be used once per day.

Proficiency with a Greatsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
