Blade of Bloody Mess
Weapon (longsword), very rare (requires attunement)
The decoration on the blade depicts a gruesome disembowelment that seems to writhe grotesquely out of the corner of your eye. You have a +2 bonus to attack and damage rolls made with this magic weapon.
When you reduce a creature that has blood to 0 hit points using this weapon, the creature sprays a fountain of sanguine mist in a 10-foot radius. All creatures in this area are coated with blood. Hostile creatures within that area must make a DC 17 Wisdom saving throw or become frightened of you for 1 minute. This magic weapon deals an additional 1d8 psychic damage to a creature that is frightened in this way. At the end of each of its turns, a creature can repeat the saving throw if it is no longer within line of sight, ending the effect on itself on a success. Additionally, for 1 hour while you are coated with blood you have advantage on Charisma (Intimidation) checks.
Sanjuro stepped towards the trembling merchants as a thick red mist rained down, soaking their robes and coating every inch of exposed skin. The droplets were hot and smelled of iron. He licked the blood from his lips and grinned; the exsanguinated bodyguards spouted the cost of bravery with each fading heartbeat. There was nothing they would deny him now.
