You can get Enhanced Devoted 3 perk with Faceted or Zaros components.
Faceted is new component, that you can get from disassembling crystal flasks.
The perk have 4.5% chance per rank on being hit that protection prayers will work at 100% (or 75% in PvP) for 3 seconds. This does not stack with devoted.
Look like it is 100% guarantee with 4 * Faceted + 1 * Zaros.
With 5 * Faceted, i got Crystal Shield 3 perk.
