Diablo 2’s long-awaited expansion, Eternal Collection, has barely launched, yet players have already exposed a flaw in the game’s design that turns the warlock class into a walking cheat code. The solution? A demon so durable it laughs off attacks meant for the player, while a carefully calibrated skill redirecting damage ensures the warlock never takes a hit.
At its core, the warlock was designed as a summoner—one who binds demons to serve as both weapons and shields. But the mechanics intended to balance risk and reward have instead created a loophole so glaring it renders the class nearly unkillable. The breakthrough relies on two key features: Blood Oath, a skill that siphons damage from the warlock into their pet, and the existence of demons in the game that are functionally immune to all damage types.
The execution is deceptively simple. By stacking gear with skill-point bonuses, a player can push Blood Oath* to 99% efficiency, ensuring that almost every hit meant for the warlock is absorbed by their demon instead. The remaining 1%—the damage that slips through—is neutralized by two pieces of legendary gear: Treachery, which grants near-total elemental resistances, and The Rising Sun amulet, which converts all fire damage into healing. The result? A warlock that survives even against the game’s toughest bosses, including the expansion’s new additions.
The demon itself is the real star of this build. Certain varieties in Diablo 2 are resistant to all damage types, making them the perfect sacrificial tank. Summon one, and the warlock becomes a spectator to their own battles—taking no damage, healing from attacks, and leaving the demon to absorb everything. The trade-off? The warlock’s damage output drops significantly, but with the right weapon—like Malice, one of the game’s most powerful—even slow, deliberate combat becomes viable.
This isn’t just a fun exploit; it’s a revelation about how Diablo 2’s systems interact. The game’s developers have yet to address the imbalance, but given how quickly such discoveries are patched in competitive titles, this build may only be temporary. For now, players have a rare glimpse into how far the warlock’s design can be pushed—and how easily Diablo 2’s mechanics can be bent to defy its own rules.
- A warlock build in Diablo 2: Eternal Collection achieves near-invincibility by redirecting all damage to an immune demon.
- Blood Oath (maxed at 99%) and legendary gear (Treachery, The Rising Sun) eliminate nearly all incoming damage.
- Certain demons are resistant to all damage types, serving as living shields.
- The warlock’s damage output is low, but legendary weapons like Malice compensate.
- This exploit is likely temporary, as patches often follow quickly in Diablo* titles.
