Description

You are immune to necrotic and cold damage and vulnerable to fire and radiant damage while you wear this armor. Additionally, you are imbued with soul-devouring energy. When you hit with a melee attack, the target takes an extra 3d6 necrotic damage, and you regain 3d6 hit points. If you gain hit points above your maximum, you immediately gain a level of exhaustion, and the soul-devouring power of the armor ends until the next dawn.

This armor is made of narrow vertical strips of metal riveted to a backing of leather that is worn over cloth padding. Flexible chain mail protects the joints.

The wearer has disadvantage on Stealth (Dexterity) checks.

If the wearer has a Strength score lower than 15, their speed is reduced by 10 feet.
