I just saw a random white circle similar to the yellow one you see after beating the iron golemn that takes you to Anor Lando. Do these teleport you somewhere? Because I can't see to get them to work...
They add a temp boost to miracles, e.g. if you have the heal miracle equipped it will gain the same circle on the icon, using it will give a slightly higher rate of healing.
I've been wondering about these for ages. What makes them appear?
Wow..I thought that was some indication of multiplayer/co-op/messages after seeing an orange message pop up under one. I'll have to try this. Sweet.
