Arcane - Data Driven Enchanting Power Overhaul

Arcane exposes Minecraft's enchanting power system to data. Bookshelves give a fixed power of one, and vanilla does not let a bookshelf-like block that doesn't respect block states count differently. The mod adds entries to the enchantment power provider tag, so blocks such as soul torches, sea lanterns, crying obsidian and vanilla mob heads can be given a set power value, with lit and candle-count variants handled separately.

The mod is aimed at data pack and modpack developers, though mod developers can also use it. To change a value, a developer overrides the matching file inside the arcane test data namespace, which is a simpler route than editing the game's hard-coded bookshelf rules. Arcane is server-side only, so players join without installing it, and the code is open source under the MIT License. Files exist for 1.21 – 1.21.4, and Fabric is the only loader.
