Always Run Strongrooms on Diablo 4 Items Torment III or IV

Difficulty matters. At Torment III and higher, Strongrooms unlock unique Pillar Buffs and boss spawns that dramatically increase your loot.

Why Torment III+ is mandatory:

A special Pillar Buff becomes available that guarantees a boss spawn at Tier 3 attunement.
Elites like The Butcher can spawn, dropping enormous attunement bonuses and elite gear.
Higher difficulties = better base loot tables for Horadric Tomes, Jewels, and crafting mats.

Running Strongrooms on lower World Tiers significantly limits your reward potential-especially if you're chasing Idol from Below or crafted Horadric Jewels with rare properties.

Strongroom Reward System: How Attunement Works

Everything in a Strongroom revolves around attunement-a score that measures how well you're doing. Attunement is earned by:

Killing monsters.
Triggering Pillars (especially high-value ones).
Slaying bosses and elite waves.

What you get from strong attunement:

Horadric Tomes - Essential for crafting endgame Horadric Jewels.
Horadric Phials - Used in Jewel crafting recipes.
Gem Fragments - Fed into the Lapidary, a workstation that fuses Jewels.
Rare Jewels - The ultimate reward. Jewels have powerful seasonal effects, especially if crafted with Tomes and Phials from Tier 3 runs.

The higher your attunement tier, the more chests spawn at the end, and the higher their quality. It's a direct, skill-based path to buy Diablo 4 Items endgame upgrades.
