Grants Armour equal to 160% of your Reserved Life to you and nearby Allies 
Note: Because Radiant Faith is classified as a buff and not an aura, Aura effect does not increase the amount of Armour and Energy Shield the Guardian grants. However, those receiving the buff can increase the amounts received by their own Increased Armour and Increased Energy Shield stats. Radiant Faith being classified as a buff has the added effect of multiple instances stacking, though it is unknown if this was nerfed after 3.1 Note, that while the wording is similar to the Hierophant's Sanctuary of Thought, the mechanics are quite different. Sanctuary of thought functions as a conversion so Increased Maximum Mana and Increased Maximum Energy Shield mods stack with each other additively. Radiant Faith grants the percentage of your actual mana as base energy shield, so Increased Maximum Mana and Increased Maximum Energy Shield effectively stack multiplicatively with each other, which allows for extreme stacking of energy shield with proper gear.
