In Shining Armor

In Shining Armor is a perk in the Fallout: New Vegas add-on Dead Money.

Effects
You gain +2 DT against energy weapons while wearing reflective eyewear and an additional +5 while wearing:
 * Advanced radiation suit
 * Chinese stealth armor
 * Gannon family Tesla armor
 * Legate armor
 * Legion centurion armor
 * Metal armor
 * Metal armor, reinforced
 * NCR Ranger combat armor
 * NCR Ranger patrol armor
 * Radiation suit
 * Recon armor
 * Remnants power armor
 * Space suit
 * T-45d power armor
 * T-51b power armor

Bugs

 * The all-purpose science suit, Brotherhood T-45d power armor, Brotherhood T-51b power armor, and NCR salvaged power armor are not affected by this perk. (The corresponding salvaged power helmet is affected by this perk.)
 * This perk does not provide any DT boost due to the fact that the parameter that is referenced in the GECK is "Energy" instead of "EnergyWeapons". This means that the function "IsWeaponSkillType" will never return a value that can activate the perk effect, because there is no weapon skill called "Energy".

Behind the Scenes

 * The name of the perk is a reference to the phrase "A knight in shining armor".
 * The +2 DT effect for wearing reflective eyewear is handled by a separate, hidden perk.
