So, I’ve apparently been linking the outdated version of Direwolf20’s Mystcraft spotlight. Whoops. 😛
While the more current one shows up on the right hand side of the screen, not everyone notices it (or can see that).
So here’s the most current tutorial from Direwolf20 explaining how to use Mystcraft features and mechanics. Between this and the writing tutorial (which I will link here again just for giggles) I think that should cover all you need to know to start Mystcraft. If you really want to know how stuff works, be sure to check out the wiki or ask on the Mystcraft forums!
I’ll also go through the recent release posts and update the links there.
