What Is the Plague Knight in Diablo 5?
Plague Knight is a newly announced, heavily armored class in Diablo 5. GamesRadar’s report from Blizzard’s BlizzCon panel describes a character that spreads disease and consumes it to gain power.
The key idea is not simply “a knight with poison.” Disease is described as something the class both spreads and draws power from.
| Step | What the description establishes |
|---|---|
| Spread disease | The class applies disease as part of its identity. |
| Consume disease | The description gives disease a second use, beyond being spread. |
| Gain power | Consuming it benefits the Plague Knight. |
Why now
The BlizzCon 2026 reveal introduced Plague Knight as a new class name with a disease-based concept.
The connection
Why here
This is a plain-language reading of the announced concept, not a tested rotation or a list of abilities. The description does not specify how quickly the cycle happens or which button triggers it.

Context
What is supported—and what is not established here?
| Topic | Evidence available for this explanation |
|---|---|
| Game and class | Plague Knight is identified as a new Diablo 5 class. |
| Broad identity | Heavy armor and a disease-centered concept. |
| Core concept | Spread disease, then consume it for power. |
| Named skills, weapons and resource rules | Not established by the cited class description. |
| Damage numbers, best builds or class rankings | Not established by the cited class description. |
“Not established here” does not mean Blizzard has never discussed a topic. It means these sources do not support adding that detail to this explanation.
For now, remember the class through its stated concept: heavy armor, spreading disease, and using that disease for power. A detailed build would require evidence beyond this reveal description.
