Go to the Temple of Growth ( -449, 49, -857 ) /waypoint -449, 49, -857 and click the urn
The praying urn is only up when a big group of guards around it is up. You have to either sneak to it or pray while fighting (golems see invisible, it is possible to sneak between them, but very difficult)
There is also another urn in the same room, guarded by only one mob, this urn can also be used
