Invulnerable Shield (3.5e Spell)

''With a long string of words, you bind an object to your survival. The object begins to glow with a shifting light, and you stop cutting yourself while cooking.''

When you cast this spell, choose an object within close range that has combined hardness and hit points no greater than twice your caster level. Until that object is destroyed, you lose line of sight to it, you lose line of effect to it, or you come within 10' of it, you are invulnerable. While invulnerable, attacks cannot hit you.

A Spellcraft check to identify this spell also identifies which object is sustaining it.
