Curently is a bit hard to know where to start on this mod. Would be nice to have something similar to Create or Ars and their achievement tree that shows where to start and where you can go on the mod. So far, I had to look on YouTube on how to start this mod, and most of them are from older versions of Blood Magic.

It would make a huge quality of Life to have an Achievement tree so new players know where to begin and where to aim in this mod, prolonging the enjoyment of it.

The mod's documentation is the Sanguine Scientiem. It is a Patchouli Book, and has a "Getting Started" link on the opening page (left side).

Edit: In case you are on 1.20.1 but haven't updated to V3.3.2+ yet (released a few hours ago), the recipe isn't showing up in JEI but can still be crafted using a Book + Glass.

Yes, I'm on 3.3.2-44 in 1.20.1. Thanks for the guide.

But still, I think an Advancement for the mob would be nice, especially since I had no idea of the starting guidebook.
Ars have a similar approach, with a guidebook and an advancement tab to remind people of the guidebook.
