The caster of Armor of Faith receives significant protection against melee, ranged, and magical attacks. This magical armor is a force of energy that absorbs a portion of the damage intended for the caster. At 1st level, the damage resistance is increased by 5%, and it improves by 5% every 5 levels of the caster: For example, a 20th-level priest would have +25% damage resistance if protected by this spell.
Although name and description already exist in the game files of the original Icewind Dale, the spell itself was only implemented in the Enhanced Edition.
