Improved Grindstone
Lightweight Paper 1.21.11 plugin that reroutes grindstone disenchantments into books, with optional cross-material transfer support.
Features
Slot 0: enchanted source item.
Slot 1 can be either:
- A normal book (optionally can be a special book) to extract enchantments into an enchanted book.
- A compatible target item (same archetype, different material allowed) to transfer enchantments directly.
Extraction keeps the source item (disenchanted) and gives an enchanted book with removed enchants.
Transfer keeps the source item (disenchanted) and returns the target item with transferred enchants.
Optional cursed-enchantment capture toggle.
Separate XP-cost toggles for extraction and transfer.
Separate configurable XP percentages (default 50%) based on estimated enchanting-table cost of the moved enchants.
Commands:
/improvedgrindstone toggle/improvedgrindstone status/improvedgrindstone cursed/improvedgrindstone xp/improvedgrindstone transfer/improvedgrindstone transferxp/improvedgrindstone specialbook/improvedgrindstone reload
Configuration
Configure behavior in config.yml:
feature-enabled: true
capture-cursed: true
book-xp-cost-enabled: true
book-xp-cost-percent: 50.0
transfer-enabled: true
transfer-xp-cost-enabled: true
transfer-xp-cost-percent: 50.0
require-special-book: false
special-book-ids: []
max-enchants-per-operation: 16
max-operation-item-bytes: 24576
special-book-ids accepts namespaced IDs (for example dingus:blah).
If special-book-ids is empty, any non-vanilla namespaced marker is accepted (item model, plugin PDC key, or namespaced display name).
max-enchants-per-operation is a safety cap. If a source item has more enchantments than this value, the grindstone operation is blocked to avoid oversized/unstable enchant payload handling.
max-operation-item-bytes is an additional safety cap on serialized item size (source/result/bonus). If any item involved exceeds this size, the operation is blocked to prevent unsafe payload handling.
XP-cost notes:
- Vanilla enchantments use their estimated enchanting-table costs.
- Custom enchantments are assigned a rough vanilla-equivalent cost from their level, using the highest matching vanilla cost as the baseline.
Compatibility
Designed for Paper 1.21.11.
