Changed 3 rubies from Dragagon's build.
removed r1 Frenzy and r2Glowing ray then took r3 Severe Punishment, r3 Reparation and Thunder gleam.
The reason is.
1. r1 Frenzy is quite useless. 50% more dmg of particle of light for just 1 hit per 50sec. So better to take perma +15% dmg of Smite.
2. Cleric's main aoe dps skill is both dots(cleansing flame and heavenly smite). So even without Glowing ray ruby, you still can do decent aoe dps. I think it's better to maximize your single target dps instead of aoe.
