This artifact katana was passed down throughout the Dorobo clan's lineage. From clan leader to clan leader, it slowly became a stronger, more refined sword over the generations of harrengon that wielded it. It now contains the soul and curse of Lymeas, The Cursed Shade Of Revelna. Once unsheathed, the wielder will begin to exhale black clouds of smoke from their mouth and nose when breathing. While attuned to this sword, the wielder has immunity to necrotic damage and the frightened status.

The wielder may use two charges to do a 45 foot dash, transforming into a pure black gas. Anyone in the line, foe or friend, must roll a con save. On a failed save, they take 4d10 necrotic damage and suffer the blinded status for a turn as this black gas causes their eyesight to fade as its ingested. On a success, the creature takes half damage.

The wielder may use two charges to launch a slash of black mana at an enemy from 60 feet away. On a hit, it deals 6d10 necrotic damage and any creature within 5 feet of the target takes 2d6 necrotic damage as some of the mana shatters and shoots off in random directions upon impact like glass being shattered.

The wielder may use a charge to use their reaction to become black smoke when being attacked. Becoming this black smoke allows the target to avoid being hit (this works against most attacks, but will not work against attacks that do not have a physical form such as Vicious Mockery).

The wielder may use a charge to form a massive 50 foot sphere of black gas that envelopes an area. This gas cannot be seen through by any means and the only person who can see through it as the caster. While this black gas is up, any creatures moving within it can be detected by the caster meaning invisibility loses its edge.

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