After an exploit was discovered, Blizzard temporarily banned the character Zeratul from all Heroes of the Storm tournaments.
Clever Exploit Led to the Ban
Zeratul, one of the two assassins with stealth ability from Heroes of the Storm, was temporarily banned from all official eSports tournaments yesterday. The reason was an exploit that allowed players to use the “Shadow Strike” ability differently than intended by the developers.
Normally, the ability allows the hero to teleport a short distance to the enemy and attack them. However, if a nearby enemy was targeted, the ability was activated, and the target was changed at the last moment, it could bridge very large distances. The ability could thus be utilized in a way that was completely unintended – outside any kind of balancing. What that looked like in gameplay can be seen here:
In the meantime, Blizzard has fixed this issue with a hotfix and has made Zeratul available again for all tournaments.
