Spell Shield (3.5e Spell)

The target of this spell is encased in a near-skintight semi-opaque barrier of magical energy that absorbs incoming spells. This spell grants the touched creature a spell shield with 5 hit points per caster level (maximum 50), regaining a number of hit points equal to the caster's level every minute while active. Once the spell shield is brought down to 0 hit points, it collapses and the spell ends.

While it has at least 1 hit point, a spell shield, as well as any magical effects active on the creature or object protected by it, is impervious to dispel magic and similar spells.
