The following books are approved for general use in Geist.

- To check if you have the right version look at the Elemental and Industrial Rage section; if those Rages have 5 dots in each you have 1.1, if they don't have any dots at all you have 1.0 and can ask for help in getting the right version.
- Everything from the books above.
- Ease the Path (Glimpses of the Unknown, p.39): This Ceremony is approved for play but may only be used on NPCs.
