Armor of the Ravenous

A sentient suit of black plate armor created by Yeenoghu, that when donned instantly forms to fit the wearer and appears Gnoll-like. The armor controls all of its own functions but does not communicate with the wearer. While wearing this armor you gain the following benefits: 

• You gain +3 bonus to armor class.
• You can sleep in this armor and are immune to exhaustion.
• You are immune to the frightened and charmed conditions.
• The armor doesn’t impose disadvantage on your Dexterity (Stealth) checks.
• Having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until initiative ends, and you die then only if you still have 0 hit points. 
• When you reduce a creature to 0 hit points with a melee attack on your turn, you can take a bonus action to move up to half your speed and make a bite attack with the armors face plate using your proficiency and strength modifier to hit. On hit deal 1d10 + Strength Modifier. 

Curse:  This armor is cursed. When this armor is donned it immediately attaches itself to you, shunting black spikes into your body dealing 10d10 piercing damage and making it impossible to remove. When you kill a creature while wearing this armor you must succeed on a DC 17 Wisdom saving throw or descend into a madness determined by the Madness of Yeenoghu table. Only a wish spell can remove the armor's curse.

Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.
