Guide awaiting review
Earn Army of the Light Reputation
Farm reputation with the Army of the Light faction in Legion content until you reach Exalted, then continue earning reputation past Exalted to fill the paragon bar and receive a Gleaming Footlocker each time it fills.
Open Gleaming Footlocker Caches
Open each Gleaming Footlocker you earn from the paragon system for a chance at the Holy Lightsphere; one player reported obtaining it after 4 Gleaming Footlocker caches, while others have opened over 40 to 50 caches without seeing it drop.
Use the Holy Lightsphere
Once obtained, the Holy Lightsphere has a 5-second cooldown, so it cannot be spammed repeatedly.
Tips
Farming the paragon cache on multiple characters each week increases the number of Gleaming Footlockers you can open — one player farmed on 12 characters and obtained the Holy Lightsphere after 4 total caches across those characters.
