Patch 2.6.4: Set Reworks & Season of the Forbidden Archives

Patch 2.6.4 went live in mid-January 2019 and still stands as one of the biggest balance patches of Diablo 3's later years. Its focus was the class sets: a whole batch of older or underperforming sets was pushed up – in some cases dramatically – to close the gap with the dominant builds of the day, such as the Condemn Crusader and the Rathma Necromancer. Alongside it, Season 16, the Season of Grandeur, launched on January 18, 2019. For many veterans, this one-two punch of patch and season marks one of the most enjoyable moments in the entire life of the game.

The Context: A Stagnant Meta

To understand why Patch 2.6.4 mattered, you need to know the state of the endgame in late 2018. The Greater Rift tier lists had been dominated by a handful of sets for years. The Condemn Crusader running the Thorns of the Invoker set and the Rathma Necromancer with its skeleton army could reach rift levels that were simply out of reach for most other builds. If you wanted to compete in serious pushing, you had almost no real choice of class.

Diablo 3 was firmly in maintenance mode at this point: Blizzard had long since shifted most of its resources to other projects, and a small team handled seasonal content and occasional balance tweaks. Within that framework, Patch 2.6.4 was a remarkably ambitious effort that deliberately tried to close the gap between the strongest and weakest builds.

Instead of nerfing the top builds down, Blizzard took the opposite route and pulled the laggards massively upward. The result was one of the most diverse tier lists Diablo 3 ever had.

Sweeping Set Reworks

The patch became famous for the sheer scale of its damage buffs. Rather than fine-tuning, Blizzard raised many set multipliers by entire orders of magnitude so that long-neglected builds could finally clear higher Greater Rifts. Where other patches nudged bonuses by 20 or 30 percent, this one sometimes tripled or quadrupled them.

• Might of the Earth (Barbarian): bonuses lifted from roughly 5,600% to as high as 20,000%
• Thorns of the Invoker (Crusader): from 5,400% to 15,000%
• Legacy of Nightmares (cross-class): a sizeable damage boost for ring-driven builds that use no class set at all
• Additional Monk and Wizard sets were brought up to competitive levels

The Barbarian benefited enormously. Might of the Earth had previously been a nostalgic fun build built around Earthquake and Leap that had no place in serious pushing. With the buff to as high as 20,000%, it became a genuine option overnight, suddenly cracking high rift levels with the right gear and legendaries. The same applied to Thorns of the Invoker: the Thorns Crusader was already strong, but the extra boost cemented its position even further.

The Goal: Diversity, Not Homogenization

The stated goal was more diversity on the tier lists. Builds that had been pure novelties suddenly became real push options – a welcome break from years of a narrow meta dominated by a few sets. Crucially, Blizzard did not nerf the top builds; it only lifted the stragglers. This "buff upward" approach meant nobody felt punished, while far more classes and builds became viable at the same time.

Season 16: The Season of Grandeur

The season's namesake theme was as simple as it was powerful: for the full duration of the season, every Seasonal hero permanently gained the legendary power of the Ring of Royal Grandeur – with no need to equip or even find the ring. The effect applied automatically from level 1 to every freshly created Seasonal character.

That power reduces the number of set pieces required for a bonus by one. So a six-piece set bonus that normally activates only with six pieces required just five in Season 16. Importantly, the effect does not stack with an additional Ring of Royal Grandeur worn directly or slotted in Kanai's Cube – you could not double up the benefit.

Why the Grandeur Buff Was So Strong

The free ring effect opened up enormous freedom in build construction. Activating a set bonus with one fewer piece freed a precious gear slot – and in a game where every single slot decides thousands of percent in damage or defense, that is worth its weight in gold:

• A free ring slot for an extra legendary power or jewelry bonus such as the Stone of Jordan
• The ability to combine two class set bonuses by saving one piece from each
• More room for hybrid and experimental builds that normally fail on slot constraints
• Stronger defensive options, since a slot could be freed for more survivability

It was exactly this flexibility that made Season 16 so appealing to theorycrafters and push players. It dovetailed perfectly with the patch's set buffs: while the higher multipliers raised the damage floor, the Grandeur effect gave everyone the freedom to outfit that floor more cleverly. The interplay of both changes led to an unusually wide spread of different builds appearing on the solo leaderboards in Season 16.

Quality-of-Life Improvements

Beyond balance and the season, Patch 2.6.4 delivered tangible convenience updates that noticeably improved the day-to-day flow of play:

• Five additional Armory tabs per character – ten saved gear loadouts in total, making it far easier to switch between speed, push, and bounty builds
• A guaranteed Primal Legendary drop the first time you solo-clear a Greater Rift level 70 in a season – a reliable on-ramp to the most coveted item tier
• Better Primal Legendary visibility: a red beam on drop, a red pentagram on the minimap, and a red border on the item icon so no Primal goes unnoticed
• Greater Rift Keystones moved into the Materials tab, freeing up inventory space
• Legendary Potions no longer stored in inventory, managed directly from the action bar

The Armory expansion and the guaranteed Primal drop in particular were long-standing community requests. Both reduced the frustration and grind associated with collecting and managing gear, and they remain a fixed part of the game to this day.

Community Reception

The reception of Patch 2.6.4 was largely positive. Players especially welcomed Blizzard's willingness to genuinely and noticeably uplift weak builds rather than make merely cosmetic adjustments. The enormous multiplier jumps generated plenty of discussion, fresh build guides, and a wave of theorycrafting as the community tested which of the buffed sets were now competitive.

The Season of Grandeur itself is remembered as one of the most accessible and popular seasons. The free ring effect removed the biggest barrier to entry for many builds, and combined with the fresh set buffs, the entire class roster felt more alive than it had in a long time.

Placing It in Patch History

Patch 2.6.4 belongs to a run of late patches with which Blizzard kept Diablo 3 fresh despite reduced development resources. The philosophy it introduced – aggressive buffs for weak sets rather than nerfs for strong ones – also shaped the patches that followed. Later updates such as 2.6.5 and 2.6.6 continued this course by reworking further sets and introducing new seasonal themes.

The seasonal bonus effect also became a recurring concept: after the Season of Grandeur came further seasons with their own, similarly impactful bonus mechanics, including the later bonus-Cube-slot theme. Patch 2.6.4 was therefore not just a single strong patch but set a template for how Diablo 3 would continue to evolve in its late years.

What It Meant for Players

Taken together, Patch 2.6.4 was a well-rounded package: the set buffs revived build diversity, the Grandeur buff handed every Seasonal hero a free slot, and the convenience features – above all the guaranteed Primal drops and the ten Armory tabs – cut down on daily grind. For many veterans, the Season of Grandeur still ranks among the game's most enjoyable seasons and a prime example of how a mature game can be made exciting again with targeted, bold changes.
