I could make the focus names be in latin, would that work?
But to be serious, I've been trying to decide whether I want to use the Thaumcraft 2 approach and make it so that you have to discover the recipes yourself (with the wiki giving very little information), which would make the Summoner's Codex and Alchemist Notebook have a purpose, or remove them and have an extensive wiki. I think I'll probably use a combination of the two. The Alchemist Notebook and the Summoner's Codex have always bothered me, as they basically become another wiki. Also, the coding for them is driving me nuts, which is one of the reasons they won't be in the initial release.
What I think I'll do is remove the Summoner's Codex and Alchemist Notebook, as well as the Alchemist Tome, and use an extensive wiki instead. I'll replace the Summoner's Codex with a tool or item that can be used to store focuses, similar to how the Spell-book can store spells. I'll make a similar item for Alchemy that stores Catalyst and Essence.
