Teleportitis

Teleportitis is a condition which causes your character to involuntarily teleport at random intervals. These teleports can be affected by teleport control or prevented by an amulet of stasis, but differ from normal teleports in that they happen instantly and without warning. Because this may place your character in extremely dangerous situations, it is usually undesirable, and a good reason to avoid carelessly trying on unidentified rings.

There are two sources of teleportitis:

• The Teleportitis mutation (frequency rises with mutation ranks)
• Wearing a ring of teleportation (these normally generate cursed)
