Houseward (Uncommon)

This engraved block of lead, approximately 1 cubic foot in size, holds an embedded Siberys dragonshard. The houseward provides state-of-the-art magical security, and is typically embedded into the floor of the building it is supposed to protect. If any creature with the Mark of Warding spends 10 minutes touching the houseward, it can cast guards and wards without requiring material components. The area protected by the spell is determined by the rarity of the houseward. The duration of the spell is 24 days, but the effect ends early if the houseward is used again to cast the spell, if a creature with the Mark of Warding spends 10 minutes touching the houseward to end its effects, or if a houseward is removed from the area it is currently protecting. After being used to cast the spell, the houseward can't do so again until dawn the next day. Wards 2,500 square feet.
