Eldritch Cultist
The Diviner's Handbook

Forbidden Lore: Rather than risk losing their magic, an eldritch cultist using forbidden lore instead has a 15% chance of becoming confused for 1d6 rounds. Every time the eldritch cultist uses forbidden lore, the chance of becoming confused increases by a cumulative 5%, but resets to 15% after the eldritch cultist fails this check. Confusion can be given to another creature via channel punishment as normal, and creatures normally immune to confusion are not immune to this backlash effect.

This modifies forbidden lore.

Eldritch Knowledge: At first level, the eldritch cultist gains Divination as a bonus sphere (or an additional talent from that sphere if they already have that talent). This replaces the invocations class feature gained at 1st level - the eldritch cultist gains access to invocations at 3rd level, but counts his Thaumaturge level as two lower for the purposes of determining which invocations are available to him.
