Even though a robe is one of the main parts of its design, I'm a big fan of the Deepshadow chestpiece. It's the most armored healer equipment that I can think of, and it even has those metallic "clink" sfx when you walk around. I threw it on my WHM the instant I discovered it existed

The rest of the set might not be your cup of tea, though (it even has some random-ass high heels thrown in for some reason)
