Bloodlust (5e Equipment)
From D&D Wiki
Weapon (dagger), very rare (requires attunement)
As rumors and fears of vampires spread, so, too, did the...appreciation of their powers. Not wishing to forfeit their soul or inherit the thirst for blood, a group of Arcane users that preferred to walk in the shadows as much as the daylight began work on creating a magical tool that could mimic the powers of these great, though terrifying, beasts. They called such daggers that were birthed from this the "Bloodlust", signifying the origins of it's power, and its creator's hunger for more of it.
You have a +1 bonus to attack rolls and damage rolls with this magic dagger.
When you hit a creature with bloodlust, the target must make a Constitution saving throw with a DC of 14. On a failed save, they suffer an additional 2d6 necrotic damage, and you are healed for half that amount, rounded down. On a successful save, they still suffer the necrotic damage, but you are not healed. This effect can only be used 3 times per long rest.
If a creature is reduced to 0 hp from an attack from this weapon, you may, as a reaction, move up to half your movement speed and make another attack against a creature you can reach, even if you have already used your full movement this round.
