Sacred link

Sacred link was a powerful divine alteration and evocation spell used by priests devoted to Tempus, enabling them to create a magical bond between two objects.

Effects
Once the sacred link was established, what happened to one object would happen to the other regardless of the distance between them. This link would last until either one of the items was destroyed or the magic was successfully dispelled.

The items in question were held in the caster's hands when the spell was cast. The items needed to be made of the same material and be roughly the same size. The items could not be living creatures. This spell was most effective when cast upon identical, or nearly identical, items.

Components
In addition to verbal and somatic components, this spell required as material components the caster's holy symbol and strand of hair, fine wire or spider web to cast.
