Invisibility - Aetolia Online Help

6.13 Invisibility

There are a number of types of invisibility in Aetolia, and most of them
are accomplished with guild abilities, which we will not go into here.

The most common way to detect some invisibility is, for the living,     
eating echinacea, or the for the undead a spleen slice. This gives the  
thirdeye defence, which will detect some lesser invisibility.
