• State what each upgrade does to the altar, in a tooltip on each item. If numbers must be added, make them vague, rounded numbers.
• Port over the rest of the new names from the docs
• Natural Tree Gen
• More to add here later

• Fix mob spawns and mob damage/hitboxes

• Include a better in-game guide that's more step-by-step and makes objectives clear, something along the lines of the Thaumonomicon in Thaumcraft

Small problem with that last one, Gabby. Bewitchment isn't as linear as Thaumcraft is. It's extremely open-ended for what you do after you have the basic stuff made, which I believe there's a section for the basic items/tile entities.

Yes that's understandable and don't get me wrong its a good trait the mod has. However, I just don't think its features are boasted enough, it doesn't really show you the cool things you can do easily enough. I thought Witchery had the same problem, I remember watching and re-watching videos in a youtube series and having to take notes just to find out what I can and should do with it.
