Ritual HexSource Occult Origins pg. 24
You are well versed in ancient secrets and forbidden curses, and know how to petition powers with which you are already in contact for additional knowledge.
Prerequisites: Knowledge (arcana) 4 ranks, Knowledge (history) 4 ranks, hex class feature.
Benefit: You learn to perform a special occult ritual (Pathfinder RPG Occult Adventures 208) known as Beseeching the Patron, which temporarily grants you a hex you don’t already know how to use. You always believe that your ritual is a success, so the GM should roll the required skill checks in secret, revealing the result only when you try to use your newly acquired hex.
