20 years later, veteran WoW director says players outsmarted him completely in Ahn'Qiraj: 'All that work, and there was still an instant tell'

Former Blizzard game director Wyatt Cheng reflects on the challenges he faced as an encounter designer for World of Warcraft's Ahn Qiraj raid, released around 20 years ago. He recounts a specific difficulty he encountered with the boss The Prophet Skeram, who splits into illusions at various health thresholds. Cheng wanted the copies to have half the health of the real Skeram, so they would drop in health faster under DPS rates.

He envisioned raids carefully analyzing which illusions were dying quickest to identify the real Skeram and focus their attacks accordingly.

However, Cheng admits he was outsmarted by the players. They found various ways to spot the real Skeram, such as using UI mods that read creature IDs, mismatched localisation strings, or even sending a hunter pet to attack the boss before the split, which would lock the pet onto the real Skeram. Some players also opted for mana-burning the copies, since they spawned with full mana while the real Skeram didn't.

Despite Cheng's best efforts, he faced an ongoing arms race with the players, constantly trying to describe the real Skeram and adjust his design. While Cheng acknowledges that players outsmarting the designer is not ideal, he remains humble about the situation, emphasizing that if it's a genuine bug or exploit, the game will be fixed. He considers players outsmarting him to be part of the game's rich history.
