You and the subjects each make a small cut in your palms (dealing no measurable damage), and then clasp hands, allowing your blood to mix and flow into each other's bodies.
This spell forges a mystic connection between you and the subjects so that you and they count as touching for the duration of the spell. You may cast spells with a distance of touch, short, medium, or long, onto any subject of the spell no matter your actual distance from each other, as long as you are on the same plane. Likewise, the subjects can cast such spells on you and each other regardless of distance, and ongoing spells that require you to stay within a certain distance work as if you were all adjacent to each other.
