High level meta-magic feat that allows the caster to create a temporal hole to a place where magic is more powerful. In other words, there is more magic crystal in that area. This allows subsequent spells to have the same effect as if cast in the area of more powerful magic.

Once high level casters have found a strong ley line (rich vein of crystal that allows for the most powerful magics), they will, as needed, create a conduit to that area. There are no known succesful attempts of creating a permanent conduit.
