Stormcaller Boss Location

The only way to encounter a Stormcaller is by entering the Aether Storm, which can easily be identified on the map as a growing purple circle with a biohazard symbol. This area is shrouded in dark clouds and it is just as dangerous as the High Threat Zone.

The zombies within the Aether Storm are high level, with most of them armored. Additionally, all zombies in this location are enraged due to the presence of the Stormcaller.
