Isn't using material links or sympathetic magic now a metamagic for initates? So normal mages need a spotter but adepts with sympathetic magic can target using a material link.
Material links don't require metamagic. Material links are stuff that was an integral part of the target--blood, hair, fingernails from a person, a brick from a building, things like that.
Sympathetic links require the Sympathetic Linking metamagic. Sympathetic links are things that were never part of the target, but have enough association to have picked up traces of the target's aura--things the target has worn, carried frequently, has an emotional attachment to, or has handled very recently can be used as sympathetic links. The examples in
Street Magic are a wedding ring, the target's Predator, and a burger wrapper the target tossed in the trash five minutes ago. The degree of the association determines the dice pool modifier applied to the ritual for using a sympathetic link. (They're less effective than material links.)
If the casters can't even get a sympathetic link, an initiate with Sympathetic Linking can also use a symbolic link. A symbolic link is an item created in the image of the target--a picture, sculpture, or doll. The classic example is a voodoo doll. Symbolic links are only as good as the worst sympathetic link--a voodoo doll and that burger wrapper would each apply a -6 modifier to the dice pool.
Links are discussed in detail on pages 28-29 of
Street Magic, which Karoline quoted, but I play a voodoo priestess and couldn't resist yammering about the topic.
