This Abyssal armor grants you resistance to necrotic damage.  

You also can cast rage 3 times per long rest. Due to the screams for children it drives the wearer of the armor mad with rage.

This armor is forged from the depths of the abyss using souls of children. The souls are still trapped within this armor and whoever wears this armor will hear them cry and scream out in pain whenever you sleep while attuned to the armor.

A greater restoration spell can set the children's souls free and let them rest in peace but it will cause 10D10 psychic damage to the one releasing the souls.

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.

Notes: Long rest, Str. 15 Required, Stealth Disadvantage
