Moon Shield

This spell creates an intangible shield of moonlight that floats along with the caster. It provides enough light to read by, cannot be made brighter or darker by the caster, and operates automatically. A moon shield gives its caster a saving throw vs. death magic against all undead aging, fear, level-and ability-draining attacks. If successful, the attacks fail (though any purely physical damage they cause is unaltered).

A moon shield also provides its caster with a +2 bonus to all saving throws against priest spells of the Sun sphere (where such spells allow saving throws) and provides a saving throw vs. spell against all attacks made on the caster by lycanthropes and by silver weapons. If these saves succeed, all damage done to the caster by such forces is reduced to 1 point per successful attack.

The material components of a moon shield spell are a piece of silver and a moonstone (both can be of any size, so long as they present at least one surface as large as the caster's smallest fingernail).
