ESR is a Minecraft Fabric mod for 1.20.1 that replaces vanilla enchanting RNG with a system built around deliberate choice and limits.

Instead of rolling the table for hours or stacking a dozen passive buffs on one piece of armor, items are limited to a single, max-level enchantment, and options can be guaranteed by placing enchanted books in chiseled bookshelves.

• Every item can have at most one enchantment.
• The enchantment is always applied at its maximum level (placing Sharpness on a sword would give you Sharpness V stats).
• Curses have a chance to also be applied to an item along side the desired enchantment if the enchantment fails.
• Anvils are used only for repairs; combining items or books to stack enchantments is disabled.

• Place enchanted books in chiseled bookshelves around the enchanting table to guarantee those exact options on the table.
• Enchanted books placed in chiseled bookselves are consumed when used to enchant an item (this can be disabled in the config).
• Regular bookshelves nearby give XP and lapis discounts on the enchanting.
• The table interface is updated to show readable enchantment names (Sharpness) instead of Galactic runes, and includes scrollbar support when you have many shelves.

• Armor, weapons, and tools generated in loot chests spawn without enchantments.
• Enchanted books still spawn in chests, but conform to the single-enchantment cap.
• Modded and vanilla enchanted books are injected into chest loot pools with configurable weights so all enchantments have a fair spawn rate.

You can edit these options directly in the JSON file or in-game via Mod Menu:

• allowBookEnchanting
  (default: false): Enables or disables putting plain books on the enchanting table.
  
  
• consumeEnchantedBook
  (default: true): If false, books inside chiseled bookshelves are not consumed when used.
  
  
• curseFailureChance
  (default: 0.15): Chance that a random curse is added alongside your chosen enchantment.
  
  
• maxBookshelfDiscountCount
  (default: 15): Max regular bookshelves counted for lapis/XP discounts.
