EnchantOnce
A configurable mod that reworks enchanting and repairing: fixed XP costs, enchant extraction, book copying, full gear duplication, and more — all using vanilla mechanics.
Useful for spreading your favorite enchantments across different gear.
Works with rare items that are hard to obtain again.
No more exponentially increasing repair costs!
Lets you move enchantments to a book.
Cost is always 25 and doesn't depends on enchantments. You get an exact copy without re-enchanting.
Using Flint on an anvil allows you to reduce enchantment levels on books in a controlled way.
Copying a vanilla Wind Burst I book produces multiple identical copies, each marked with Wind Burst 🔒 to prevent further enchantment level scaling.
Every feature can be enabled, disabled, or tuned to match your playstyle.
