Enchanting Guide: Best Combos, XP Farming & the Table (1.21)

Maximize your enchanting table — how enchantment level works, the best weapon/tool combos, XP sources and librarians for exact books.

Enchanting

Enchanting is the fastest way to multiply your gear’s power. The key: your enchanting-table level (the lapis number) doesn’t equal the enchantment’s strength — it sets the pool of possible enchantments, and level 30 gives you access to the top rows.

How the table works

  • Place 15 bookshelves one block away (leave the middle aisle open) to unlock level 30.
  • Cost is 3 lapis + XP levels. Three choices appear; reroll by enchanting a cheap item (or a book) to shuffle.
  • Each choice has a hidden enchantment-level value that decides which enchants and how strong.

Best weapon & tool combos

Item Top combos
Sword Sharpness V + Looting III + Unbreaking III + Mending (+ Sweeping Edge)
Pickaxe Efficiency V + Fortune III + Unbreaking III + Mending (+ Silk Touch variant)
Bow Power V + Infinity OR Mending + Unbreaking (Infinity & Mending don’t stack)
Armor Protection IV + Unbreaking III + Mending; Boots add Feather Falling IV + Depth Strider
Trident Loyalty III / Riptide + Channeling + Unbreaking

Note: Mending and Infinity conflict; Mending and Fortune/Silk Touch are fine together.

XP sources that scale

  • Zombie/other mob farms (see the creeper and iron farm guides) — reliable AFK XP.
  • Villager trading with librarians: buying enchanted books and trading XP is the sustainable mid-game path.
  • Breeding + trading farmers for emeralds then converting via librarians.

Librarians: the exact-enchant shortcut

A librarian villager offers enchanted books you can choose from by cycling trades until the one you want appears. Every refresh costs a couple of emeralds. Once you lock a good one (e.g. Mending), don’t break and re-place the lectern unless you want to re-roll — a traded librarian keeps its book.

Common mistakes

  • Missing the 15 bookshelves — you cap at weak tiers without them.
  • Mending on a bow with Infinity — they can’t coexist.
  • Wasting lapis on random 30-cost rolls when you only need one enchant — re-roll cheap instead.
