Murderous Straight Razor

This otherwise gleaming implement has dark stains that cannot be polished or scrubbed off. You gain a +2 bonus to _attack and damage rolls_ made with this razor. A number of times per day equal to half your proficiency bonus, when you hit with a melee attack you can use a bonus action to channel the inherent hatred of the razor, dealing 2d6 necrotic damage. _**Curse.**_ Once attuned to this weapon, you are _cursed_ until you are targeted by _remove curse_ or similar magic. Your appearance and manner have a hint of murderous rage at all times, giving you _disadvantage_ on Charisma checks and making beasts hostile towards you. Additionally, you have disadvantage on attack rolls with any other weapon and must make a DC 14 Wisdom _saving throw_ to willingly part with the razor, even temporarily.
