Manhunter’s Blade

Weapon (dagger), very rare, requires attunement   While wielding this blade, a corrupted white light wraps around you and guides your strikes.   You gain a +2 bonus to attack and damage rolls made with this weapon. You have advantage on attack rolls made with this weapon against Humanoids and deal an additional 1d6 slashing damage to them. In addition while wielding this dagger you can cast the hunter’s mark spell at its lowest level against any Humanoid you see within range, at will. If you cast the spell in this way you cannot lose concentration on it due to taking damage, and when the target drops to 0 hit points, the spell ends. In addition, while marked by the spell, you always know the exact position of the target, as long as it is on the same plane of existence as you.
