ever though about gating a recipe book on recipes.
the idea at level 60 you can find a crude recipe kit - which teaches you all the recipes ( you currently know)
now with paper cement dust or gun powder or some other kind of dust water and an example of the item it makes ( iron helm ect) you can make the recipe/schematic.
think these would be highly traded commodities especially for old timers to help/introduce new players to the server.
just a wnadering thought
