⚠️ v1.6 UPDATE: XP Book II and III were removed, and there were some changes with item data! You can update the mod in your world without losing anything, but be sure to put your books in a crafting table to update them. Old saves won't be supported forever, this warning will be update whenever a version without the transition support is uploaded.

XP Book Upgrades

• You can update the new smithing recipes to customize the parameters of the XP Book in output, such as its new capacity or efficiency for example with your custom resource pack
• You can also add new smithing recipes in your custom resource pack to add more XP Book levels
