1. This was done at level 75.
2. Contributing buffs/trinkets are: Blessing of Kings, Avenging Wrath, Auto-Blocker, and Tome of the Lightbringer. I unfortunately don't have a second block value trinket.
3. The Tome of the Lightbringer buff fell off as I took the screenshot, immediately after the hit, that's why it doesn't show in the buff pane.
This is fun
