Diamond horseshoe

Lucky is the homeowner who owns this smooth curve of gemstone brilliance, as dropping the diamond horseshoe in one's home conveys a swathe of magical puissance effecting the following protections to all current rooms in the owner's house:

• eye sigil
• monolith sigil
• key sigil
• no prism

The horseshoe's dedication is impervious; it cannot be removed once placed in the home, though it can be touched once to update its coverage to any new room additions. Diamond horseshoes are for sale at the House of Wonders in Delos.
