DifficultyRecipes
DifficultyRecipes is a library mod that provides developers with the ability to create crafting recipes that automatically adapt to the game's difficulty level. Depending on the player's chosen difficulty level (peaceful, easy, normal, hard), different crafting variations for the same items will be available.

For convenient work with the mod, integration with NEI (Not Enough Items) is provided, which displays current information about the difficulty level and shows in which other difficulty modes a specific recipe will work.
CustomThings mod version 0.0.2-31 and above has built-in support for DifficultyRecipes, allowing the addition of adaptive recipes through JSON configuration files.
