Empowered Shrines provide a two minute bonus that increases a character's resource regeneration rate, and also reduces the length of skill cooldowns. All resources are boosted in regeneration rate save for the Demon Hunter's Discipline which receives no bonus from this shrine.

The utility of this shrine varies greatly between classes and builds. Some characters using low-cost builds receive little benefit, while others using a lot of resources can greatly improve their performance.

These shrines were added to the game in Patch 1.0.5.
