Diablo 4 player discovers new Infinite Damage exploit that literally makes the servers chug

Belial’s Return in Diablo 4: Season 9 allows players to siphon a boss’ powers to use for themselves. As it turns out, the new update allows players to deal an infinite amount of damage by using just a few boss powers and a single Legendary Aspect.

Spotted by awesome Diablo 4 YouTuber Macrobioboi, via PCG, this new exploit allows you to absolutely decimate hallways of enemies by attacking them hundreds of times a second. Using the Vampire Curse Legendary Aspect and the right combination of powers, any player can mow through the entire game.

Deal infinite damage in Diablo 4 Season 9

As explained in the YouTube video, the Vampiric Curse Legendary Aspect allows you to inflict Vulnerable to an enemy until they die. When combined with the Flesh Reaper’s Disruption boss power, enemies can be made permanently Vulnerable and stunned, and you can use the power over and over again.

Additionally, the YouTuber stacked Varshan’s Life Steal which deals a massive amount of damage when the player’s main boss power is activated. All of this combined turns into a major damage exploit that allows players to deal an infinite amount of damage, instantly wiping out rooms filled with enemies.

In fact, the damage calculations are so obscenely high with the exploit that it causes the Diablo 4 servers to immediately chug for everyone. Every player on the server will be able to feel the build in use as enemies stop moving and start shaking across the scene.

Blizzard is still working on loads of updates for Diablo 4 as the live-service ARPG continues towards its 2026 expansion. With a ten-year internal roadmap drawn up at the studio, it’ll be a long while until Blizzard leaves D4 behind for a potential Diablo 5.
