In game, with all buffs active.
This build revolves around the new Rutnick Pistol introduced in patch 1.1.8.1. The Watcher of Erulan adds some much needed tankiness and a nice skill modifier to Smite on top of the modifiers from the Bonemonger set. The Magelord rings allows us to cap Inquisitor Seal and convert about half of the elemental damage from multiple sources to aether.

Apparently grimtools does not display the physical resist buff on the shield properly: it only shows an increase to physical resist of 10% instead of 18%. Phys res in game sits at 64%.
Edited build after people kindly pointed out that the resist shred to guardians was only applied from celestial presence.
