Getting Started with Rustic Mod 1.12.2,

The Almanac is the essential in-game documentation for the Rustic mod. It contains detailed information on every block, item, and mechanic added by the mod.

To craft the Almanac, combine a Book and an Ironberry in any crafting grid. Ironberries can be obtained by breaking the leaves of Ironwood trees, which are found naturally in the world.
