The way i'd rule it in my game, and thats a stipulation.
Its a thaumaturgic block one use spell thats tied to an item. In that sence its a scene wide block spell, perhaps several spells to create a defence/offence terrain change to a single battle. Ie a area block, and a few landminds. To get this to work would be a major casting, probably a whole week of declarations like you'd use to make the family houses wards.
How many spells to an item? Depends on the items quality. A fist sized uncut diamond, resource 6 or 7 would be able to hold several spells, probably its "Quality Rating". Theirs probably also a lore limit to how much an item could hold say the quality rating times the lore skill of the caster's a good base.
Kind of a Defensive Doom Box from the tv series.
I wouldnt permit declarations for the "summoning" of one of these, its a thematic ritual, probably a story in and of itself how you came about the knowledge to make this thing. Maybe done during the week between sessions.
Its it powerful? Yes, is it more powerful than a 30shift ritual to murder someone with their fingernail clippings? Probably not.
