New Link: https://www.grimtools.com/calc/M2gz9XvN
Edit: Link updated - TY @Gnomish_Inquisition, @DeputyChuck, @XandeRoot
- Edits include: Devotion assignment swapped to maximise dot damage, Ignaffar’s Combustion relic included for Ele RR and max Inquisitor Seal (was previously Eye of the Storm), Components re-arranged for slightly more energy regen to account for dropping Eye of the Storm’s skill cost bonus, and rebalancing of resists. Due to slight skill point reshuffle, an added Ugdenbog Leather and Ignaffar’s Combustion, build now has about 100 more DA. Dropped Word of Pain, and can now fit movement augment Ultos’ Arrival into the skillbar.
OG Post:
TruthSayer disrupts the battlefield with a constant barrage of debuffs and wide reaching lightning attacks. Four lightning mortars bring the bulk of the damage, with Horn of Gandarr serving as an EMP, damaging and debilitating enemies across the battlefield. This build is great at controlling and debuffing mobs while raining divine lightning wrath from the heavens upon them. This build would work well in a team thanks to it’s powerful inquisitor seals, huge reduction to enemy damage across the field, and myriad of other debuffs to enemies that the build brings.
This is a technical build, with all skill slots occupied, and needing to drink energy potions from time to time. Movement rune now included! This build is intended to be a fun concept build, and has not been excessively minmaxed for effectiveness. 
Vid 2: SR 75

As you can see, the first three shards of SR 75 are very easy due to AOE lifesteal, AOE damage and plenty of CC, but the boss room is a little more precarious. I also accidentally pulled three of the bosses at once trying to kite Grava, and the mutators were fairly harsh. Still, I was able to come out of the boss room with zero deaths and about 6 minutes left on the clock. Not bad. I only did 75 because I am lazy. I am confident that the build can do 76 just fine. Especially with different mutators.
TruthSayer’s Tactical Techniques:
:: Horn of Gandarr debuffs enemies
30% damage reduction
200 reduced defensive ability
12% attack damage converted to health.
~1s cooldown
Being able to spam an AOE skill like Horn of Gandarr with the attack damage converted to health, 100% of pierce damage converted to lightning (plus extra lightning damage), plus 80% weapon attack damage makes for constant healing and constant energy leech from all enemies in the area. As far as I can tell, the highest crit I’ve achieved with this is around 220k, but I think between 90-120k is more common. That means that against most individuals of enemies, a single cast of this skill will fully heal you. It hits everything in a 12 meter area.
Storm Box of Elgoloth also adds to DA shred to give a total of 300 DA shred to enemies.
:: Lightning Mortars
Four mortars with 100% phys and fire converted to lightning make up a strong portion of this build’s damage. Reckless Tempest is assigned to them so that they may provide additional AOE lightning damage.
:: Ulzuin’s Wrath
On top of Horn of Gandarr’s healing, AOE lightning spam and mass confusion, Ulzuin’s Wrath is constantly proccing, hitting enemies for additional lightning damage and healing you for 15% of it, and is knocking down enemies.
:: Light of Truth + Arcane Bomb
This build lacks DA, so it’s important that it can debuff enemy OA. Stacked OA totals at 295 reduced OA to enemies.
:: Searing Light
30% Fumble/Impaired aim to enemies is like a 30% reduction of overall incoming damage from most damage sources. Super helpful to prevent incoming attacks!
:: Inquisitor Seal 21/12
Divine damage absorption! 392 to be exact. Delish.
:: CC
Flashbang, Ulzuin’s Wrath, Horn of Gandarr, Heavy Ordinance, Reckless Tempest and Hand of Ultos are constantly confusing, knocking down or stunning trash mobs. This is a big part in what makes SR 75 so smooth during the first three shards. These are clearly less powerful when versing bosses.
:: Failsafes
At 66% hp, Blast Shield procs, which also opens up Giant’s Blood to proc for healing and regen. Blast Shield is not highly ranked, it is mainly there to give Giant’s Blood something to proc on when your HP starts dropping. Additionally, Rewind Fate serves as a second circuitbreaker, fully restoring your HP should it drop below 25%. Very helpful if you’ve taken an unfortunate critical hit or something!
