Casting
Overview
BBL Casting is a tinkers inspired mod that allows you to smelt resources into molten variants as well as modify your equipment with Equipment Modifiers. Casting supports various materials added by other mods such as tin, osmium, enriched iron and many more! Also has GuideME support to help understand how it works
Multiblock Controller (Moved to own mod in 26.1 +)
The Multiblock Controller is a customizable multiblock that is the heart of your resource processing. Using the controller you can melt items into molten resources. These resource can either be extracted from the multiblock using the Multiblock Valve, mixed into a different alloy using the Mulitblock Mixed or hardened into item using the Multiblock Solidifier. All these also have simple versions which just require the block connected to each other.
Equipment Modifer (Moved to own mod in 26.1 +)
The equipment modifier allow you to use molten and/ or item to give your tool unique traits such as Repairing, Excavating, Flight and man many more. Equipment modifiers can be used for both Armor and Tools with each modifier having its own list of valid equipment that it can be applied to
Pack Devs
Using BBL Compat adds support for more mods and kubejs recipes. Add recipes in the mod can be modified using data packs, there are various configs for equipment modifiers to change the max level and effectiveness of some modifiers. You can also create your own modifier sets for example making a diamond accept the soulbound modifier so you can keep it on death
