Diablo 4’s Lord of Hatred expansion received a patch on or around May 13, 2026, intended to fix issues with the Glynn's Anvil Legendary power but instead created a bug that allowed players to achieve near-immortality in combat [1].
Glynn's Anvil grants damage reduction per stack of resolve, capped at 8 stacks by default, providing roughly 24% damage reduction under normal conditions [2, 1]. The patch inadvertently enabled resolve stacks to exceed the intended cap due to a gear stat exploit. Players reportedly reached as many as 44 stacks according to one source, or up to 58 stacks per another [2, 1].
With the multiplicative nature of damage reduction stacks, the bug allowed players to surpass 100% damage reduction, significantly lowering damage taken. One user's in-game character damage taken dropped from 30,000 to 4,000 due to maximizing resolve stacks and Glynn's Anvil effects [2, 1]. An anonymous player on Reddit stated, "With the now fixed Glynn’s Anvil aspect on my legs and with 58 max stacks of Resolve my toughness in combat went from 9 million to 52 million. Don’t sit on this aspect, it’s extremely strong, lets you basically roll off most other defensive rolls on your gear and other places to put in more offence" [1].
Players exploited the bug by equipping Glynn's Anvil on multiple gear pieces and stacking resolve through stat upgrades to achieve the excessive stacks [2, 1]. This scenario followed the Lord of Hatred expansion launch on April 28, 2026, which originally featured a bug causing Glynn's Anvil to provide less damage reduction than intended [1].
The patch aimed to correct the initial issue but instead introduced this imbalance, affecting gameplay worldwide [2, 1]. The exact damage reduction percentage per stack is debated, with sources citing between 2.5% and 4% per resolve stack [2, 1].
The development overshadows the technical fixes introduced, prompting anticipation for a swift corrective patch to restore proper balance.
