This spell protects a single being against all magic in the following ways: The recipient receives a +3 bonus to all saving throws vs. spell; the recipient is rendered immune to all Illusion/Phantasm and Enchantment/Charm spells for the duration of the spell shield (previously existing magics of this sort are permanently broken by the shield), and the shield absorbs 1d2 points from each die of damage inflicted by any spell that does affect the shielded being.
Notes: Restricted to priests of Mystra, from the Forgotten Realms setting. This spell is found only in a few exceptionally rare tomes.
