Splint Armor of the White Rose

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.
