Depends if you use bookcases or not and if you can not use enchants on your own. But I must say having a sign that has every enchant in the game on it is hilarious.
heh
that's better than the holy planks of Sengir
We had a nice little discussion about enchanting on a different forum, where I had a simplistic idea. What if enchanting was more like... cooking. Imagine it like this. Exp would be like a fuel, You could turn the rate at which you consume it up and down. Different ingredients require different amounts of XP to fully deliver the sought after effect. Some lose power gradually, some gain it, some have a peak in there somewhere, perhaps even two, but burn off into nothingness when you overdo it. The ingredients could be common things, the thaumcraft essentia system could play a role.
This way, by following a certain recipe, you'd always get a certain enchantment. However, mistakes could be always made. It's science! It's art! It's magic! It's enchanting with a twist!
Anyway. Let me put the train back on track:
I'm planing on matterfabricating most of the rubies needed for the coils. Using diamond dust (from wither skellies) instead of scrap, this should.. be possible. The rest will be redstone. I'm planing on doing this with as little digging as possible.
