Light damage

General

 * Light damage is a damage type found on monk Smiting Rods and Smiting Staves. And on other Elonian Monk weapons.
 * Light damage does not ignore armor, but nothing protects specifically against light damage.
 * There are no skills that cause light damage. Some monk and dervish skills cause holy damage, which is functionally the same.
 * Light damage is neither physical nor elemental damage.
 * Light damage deals double damage to undead creatures, such as minions.
 * The Necromancer's Tormentor's armor takes additional damage from light damage.
