(5 point Merit)
You are able to utilize one of the Spheres of magick with a greater degree of ease than others. In aprevious incarnation, you were extremely proficient in one of the Spheres--so much so that your Avatar has managed to draw a small portion of that knowledge through into this lifetime.
Select a Sphere; when spending experience points to gain levels in that Sphere, you pay three-quarters of the normal cost. This Sphere must be declared during character creation. Of course, this Merit may only be purchased once.
