Minor Spell Invulnerability
(Abjuration)

Range:  0
Components:  V, S, M
Duration:  2 rounds per level
Casting Time:  3
Area of Effect:  The caster
Saving Throw:  None

This spell creates either an immobile, faintly shimmering magical sphere around the caster that prevents any 1st-level spell effects from penetrating or a mobile, faintly shimmering field around the caster that prevents any 1st- and 50% of all 2nd-level spell effects from penetrating. This includes innate abilities and effects from devices. However, any type of spell can be cast out of the magical sphere or field, and these pass from the caster to the subject without affecting the globe or field. The caster can enter and leave the globe version without penalty: the field disappears when the caster leaves it. Note that spell effects are not disrupted by the globe or field unless cast directly into it. Area effect spells, however, are disrupted within the globe or field only as long as the caster is inside the globe or field.
The material component of the spell is a glass or crystal bead that shatters at the expiration of the spell.
