Arcane: Behind Bars is a Minecraft mod inspired by the world of Arcane. It adds new materials, machinery, weapons, runes and other items based on the technology and discoveries seen in the series.

About Shimmer and Version 2.0
Shimmer is not an implemented feature of the new Version 2.0 update. Any Shimmer-related content that may still be present in the mod is extremely experimental and should not be considered finished. Its mechanics, recipes and effects are subject to change, and it may not work as intended.
Shimmer will be developed further in a future update. For now, it is not part of the intended Version 2.0 gameplay experience.
Recipes and Help
For crafting recipes and item information, I recommend installing Just Enough Items (JEI).
