The Astral call bug is a fairly serious loophole in NetHack's handling of the call command when using telepathy. The bug is listed as: SC343-11: It's possible to easily find the identity of a high priest on the Astral plane. SC343-12: Hero using telepathy can abuse Call on the Astral Plane. It works as follows: 1. * Reach the Astral Plane with telepathy, then blind yourself 2. * Use Call to select a @ which looks like it might be a high priest(ess) 3. * Call him or her anything you like The game will then tell you: The high priestess of doesn't like being called names!
