Aranen's Divinial Armor

This spell is effective only upon those warriors of the same alignment as the priest who are also wearing metal armor. The spell temporarily turns the warriors into holy warriors, with hit point and Armor Class benefits tied to the caster's level. The priest casting the spell can affect one warrior for every two levels of experience (round up), to a maximum of 5 warriors. For example, a 3rd level priest can affect two warriors. The spell duration is two rounds, plus two rounds per caster level. Thus, a divinial armor spell cast by a 6th level priest lasts 14 rounds.

The material component is the caster's holy symbol.
