ENN: Keya vefa jedan tasa Vassago

From the Goetia:

“This Spirit is of a Good Nature”

“his office is to declare things Past and to Come, and to discover all things Hid or Lost”

Vassago’s main office is in the area of divination of all kinds, however it has been noted, and I have found it best, to use the method of skrying when communicating with Vassago.

Vassago is a gentle spirit and definitely one of the better ones to work with when beginning.

In terms of divination, this is in particular reference to knowing all things past and future, finding lost and hidden things, but Connolly also mentions finding out if an enemy has cursed you or is doing something behind your back. In this regard, VK Jehannum mentions that Vassago will defend the sorcerer and obliterate their enemies as well as transform the Witch into a dark and horrific being through dark alchemy.
