The Hammer of Grace

The Hammer of Grace is a decent one handed mace for a Pre-MC healer. About as good as your going to get from 5-man instances.

Source
The Hammer of Grace can be found in the Chest of The Seven after defeating the ghostly dwarves in the Summoners' Tomb in the Blackrock Depths.

Background
These rounded hammers produce a calming white glow. Originally crafted by followers of the Light, they are formidable weapons in their own right, but become even more effective in the hands of healers.
