A Summoner's Journal
From Diablo Wiki
A Summoner's Journal is dropped by a Cultist found performing a ritual on the bodies of four Khazra in the Southern Highlands of Act I. The Cultist is always located on the right hand side of the map as indicated in this map.
You do not need to be on any particular quest in order for the Cultist to appear.
Only one of your characters needs to find the journal for you to be credited with it.
To find out which journals you have found so far go to your Achievements list (press Y) and check:
