With Reign of the Warlock, Diablo 2: Resurrected is not just adding a new class and new itemization, it is expanding the game’s endgame structure in a meaningful way. For years, the pinnacle challenges in Diablo 2 revolved around the same bosses and high-efficiency farming in Terror Zones. Power scaling was mostly about optimization: clear faster, farm smarter, stack more Magic Find.
The Colossal Ancients change that equation.
Rather than another repeatable farming target, this encounter is positioned as a deliberate, high-stakes challenge. It requires you to be prepared, have a good strategy, and a very good build, not just raw damage output.
Here is how the fight is unlocked, how its scaling mechanics work, and what makes its exclusive Unique Jewels worth getting.
How You Unlock the Fight
The encounter begins at the end of Terror Zone runs. After defeating a Terrorized Act boss, there is a chance for statues tied to the Ancients to drop.
Collect all five statues and combine them in the Horadric Cube. Doing so opens access to the Colossal Ancients encounter, positioned as a new Uber-tier fight.
This immediately gives Terror Zones more long-term value, especially for players who want more pinnacle content.
The Gauntlet Mechanic
The fight itself escalates in difficulty. When you kill one Ancient, the remaining ones grow stronger and unlock additional abilities. Every decision matters. Kill order matters. Survivability matters.
It is less about raw damage and more about control, positioning, and execution.
If your build has weaknesses, this fight will expose them.
Exclusive Unique Jewels
Victory comes with Unique Jewels. Each Ancient drops one of two specific jewels, depending on the boss you killed last:
- Talic
- Defender’s Fire
- Defender’s Bile
- Korlic
- Protector’s Frost
- Protector’s Stone
- Madawc
- Guardian’s Thunder
- Guardian’s Light
All jewels require Level 75 and function similarly to Gheed’s Fortune. This means that you can only equip one at a time across all gear.
The Colossal Ancients feel like an attempt to add a more structured, build-check encounter to D2R, something that pushes optimization beyond “can it clear fast?”
But one thing is clear: if you want to test your new Warlock, or any build, this is where you will do it.
