So I'm most familiar with people using taglocks in the form of things which contain DNA from a person, a picture of a person, items from a person, etc.
However, what about using an item which has not belonged to a person in a long time, perhaps years? Has anyone here teased out the energy from long ago in order to target a person? For example, a necklace that was once a childhood friends but is now yours, or a plastic container you ended up with from so-and-so?
When I pick up certain older objects, I can sometimes feel that residual energy lingering, but it is very muddled with the other energies of the object. I am not currently familiar with methods for energy extraction, or if it is even possible to do smoothly and cleanly.
