OK, so I rewrote part of the grammar’s parsing again. :P
Particularly, I did this to allow me to balance the rules differently. Now the grammar will not change colors or phases or the like that you have written, while still being able to generate its own complex values.
This build also includes a lot of work on bugfixes and other balancing, as well as some new symbols and a system for automatically adding registered fluids as symbols.

Keep in mind that you need link panels to make books! This is for both descriptive and linking books.

To recap: there is only one download (found at the bottom of this post); This file is the universal install for client and server; it no longer goes in the jar.
Mystcraft goes in the mods folder.

If you are still lost on the 0.10 series, check out Direwolf20′s Mod Spotlight! Direwolf20′s Mod Spotlight for 0.10.4.00
If you are having trouble with writing, check out Direwolf20′s Writing tutorial!
Note that there are a couple changes in this release, particularly that colors and things are easier to write. If you follow the tutorial, you’ll be great.

Also, it has been suggested that I provide an optional Adfly link for people. I’ll give it a whirl. Thanks to those who suggested and supported it. :)
