Someone asked: If my class changes DURING an event (e.g. a Spirit Forge is cast on me), do I get new Paths if I have already purchased for that event?
Answer: Yes, but not until Logistics. You must replace any Paths, Tools, and Boons that are no longer accessible to you due to class restrictions with something more appropriate. Until then, you will keep the ones you already had. This may mean that some of the benefits you are receiving are no longer of value (e.g. Overwhelming Force, but you no longer have PTD skills available).
