I recently discovered the Radiating Orb build, that thing is busted! Together with the Cloak of Displacement you’re basically untouchable! Everything around you will have around 8 Orb stacks permanently, and every stack reduces their attack rolls by one, on any target! It also does a nice bit of passive radiant damage, but that’s honestly just a bonus.
I’d say the bread and butter of this are the helm and the chest armor:
Holy Lance Helm: Cause radiant damage to enemies who miss attacks against you
Luminous Armor: Whenever you deal radiant damage, trigger a shockwave that applies Radiating Orb in an area
Other items then synergize with this setup and make it even stronger:
