Iron Mother (Patreon)

Armor (shield) , very rare (requires attunement)

The countenance of the Bloody Mother adorns this shield, beautiful and terrifying all the same in its ferocious serenity. You gain a +2 bonus to your AC while holding this shield. This bonus is in addition to the shield's normal bonus to AC.

Mother's Embrace. This shield functions as a martial melee weapon that deals 1d8 piercing damage + your Strength modifier. If you are proficient with shields, you can add your proficiency bonus to attack and damage rolls made with this shield. If the target is a creature, you can choose to grapple it (escape DC 8 + your Strength modifier + your proficiency bonus). Until this grapple ends, the target is restrained, and you can't attack another creature with this shield.

Scarlet Room. While a creature is grappled by this shield, you can use your action to force the creature to make a DC 17 Charisma saving throw. On a failed save, the target is banished to a demiplane of constant suffering for 1 minute. The demiplane is an endless expanse of shallow blood overgrown with ferrous thorns. At the start of each of the target’s turns inside the demiplane, it takes 2d8 piercing damage and 2d8 necrotic damage. The target can use its action to attempt to escape the demiplane, repeating the saving throw. If it succeeds, it escapes and is teleported to an unoccupied space within 5 feet of this shield.

Once you use this property it can't be used again until you finish a long rest. If a creature dies while in the demiplane, its body sinks into the blood of the demiplane and you regain a use of this property.

Prostrate yourself before the Mother, generous is she to bestow her love upon any of her misbegotten children. With supplication she shall accept their miserable forms and make them beautiful. With their screams we shall sound the call that paints the skies a bloody hue, as we beckon the crimson tide to drown this sinful world in scarlet.

-The Crimson Tome; Verse 65:2
