This spell creates an immobile, faintly shimmering magical sphere around the caster that prevents any 1st, 2nd, 3rd, 4th, or 5th level spell effects from penetrating (i.e., the area of effect of any such spells does not include the area of the globe of invulnerability). This includes innate abilities and effects from devices. However, any type of spell can be cast out of the magical sphere, and these pass from the caster of the globe to their subject without affecting the minor globe. The globe does not affect eighth and higher level spells. The globe can be brought down by a successful dispel magic spell.
