This is just a showcase of an off-meta, end-of-league experiment. It's a Forbidden Rite Guardian built around scaling life, mana, mana gained as ES, and mana recoup. I would not recommend playing the build as a league starter, or at all for that matter. I do, however, go over how I would change the build for 3.18, now that they've revealed the Searing Purity passive, which can help solve this build's problems. Check out the video if you like seeing weird theorycrafts put into practice!
