Lore

The Spirit Mod has a couple of lore books scattered around to make the world feel just that tad-bit more alive and to give multiple things more purpose. While they are mostly unnecessary to gameplay, most books do give some help in the early game, such as the Beginner’s Guide to Weaponry. Most of these are gameplay-oriented, however they do have some lore associated with them, but not much.

There is no current boss lore, however there may be some in the future.

The Beginner’s Guide to Weaponry.
The Beginner’s Guide to Weaponry is a guide that was written by a previous adventurer, Knight-Crusader Aurelius. It’s a transcript of an informational speech given by Aurelius, detailing multiple useful Early-Game Weapons to use. He created the book after his previous one, The Beginner’s Guide to Armor didn’t sell so well. (The Beginner’s Guide to Armor is not an actual book in-game, only weaponry exists)

An Alchemist’s Observations
An Alchemist’s Observations is a guide that was written by an alchemist, Lena Ashwood. In the book, she goes into detail about multiple potions she’s discovered while experimenting with ingredients from all around the world, namely Glowroot, Bismite Crystals, etc.
