Cloak of the Slasher

Wondrous item, rare (requires attunement)

This billowing cloak moves almost as if on its own, and trails behind you like an extension of your being. While wearing this cloak, your stealth checks are made with advantage. If you are in dim light, you can Hide as an action, even if being observed.

Curse. Once you draw a weapon, you cannot willingly drop it until you slay a creature. If you hold a weapon while wearing this cloak during a sunset, you must also make a DC 13 Charisma saving throw. If you fail, you are considered charmed and are compelled to find and slay an innocent living creature. The next morning you awake and have murky memories of the event. You cannot remove this cloak until you are subject to a remove curse spell.
