Players single-handedly defeated Prince Grommoran in WoW Classic: Season of Discovery.

Onlyfarms - Prince Grommoran defeated in WoW Classic's "Season of Discovery".

In the fifth stage of WoW Classic’s “Season of Discovery,” developers slightly updated Prince Grommoran, transforming him into a world boss for groups of 20-40 players and relocating him from the open world to a separate raid. Despite being designed for full raids, the relative simplicity of his mechanics allowed particularly skilled players, such as warlocks and shamans, to defeat him solo.

Recently, a shaman named Morzius showcased his solo victory over Grommoran. He utilized various world buffs, consumable items, and spent 1.5 hours to achieve this feat. As a result, he received full loot as if from an entire raid, including three pieces of gear and 100 gold.
