Cursed Spirit, Weapon Cache/Inventory Curse

Cursed Spirit. Cursed Spirits are invisible. This invisibility cannot be removed in any way. All their attacks are magical. 

Cursed Sight. Curses can see invisible creatures and objects.

Utility Curse. The Curse may be wrapped around one's body, its tail around the waist, its body across the chest/back and head on the shoulder. While being worn, the Inventory Curse provides AC equal to its hit points and can store infinite amounts of items within its seemingly bottomless stomach with no additional weight. The wearer may use a bonus action to equip a weapon that was stored within the Curse's stomach. When the Curse is equipped, the wearer must make a Charisma ability check. On a success, it accepts it as its master. On a failure, it makes a Strangle attack against the wearer. The ability check may be made ever 1d4 +1 minuets. While worn the Weapon Cache gains telepathy with its wearer and vice versa. Whenever an attack is made against the wearer while the Curse is being worn, and the attack does not deal damage due to the wearer's AC, the Curse receives the incoming damage. The Curse may also be targeted by an attack. When it dies, it disintegrates, spilling out all stored items. 

The Weapon Cache needs fed at least once every 4d5 hours. If it is not, it will consume 1d4 random items it is storing. The Curse can eat anything and it will sustain it.

Strangle. The Inventory Curse deals 2 (1d6) bludgeoning damage to a target wearing it.
