Are Force Domes spheres or hemispheres?
Force Domes are really spheres of magical energy, with the top hemisphere showing and the bottom hemisphere engulfing mass as a magical (not physical) “anchor”. E.g., a 3-hex Force Dome radiates 2 hexes out from the center hex, and is 5 yards (15′) in diameter. It must be cast on a patch of ground at least 15′ across, and appears to be a “dome” 7.5′ high in its center. The other hemisphere is under the ground, full of dirt, stone, or other solid junk. To uncover the whole sphere, cast Disintegrate, Earth-to-Air, Teleport Other or something similar on the mass in the sphere after you have cast Force Dome.
