The complete, up-to-date guide to how to enchant in Minecraft PC (Java 1.21.11): Level 30 setups, anvil mastery, Mending farms, RNG tricks, and perfect god gear without ever seeing “Too Expensive” again.
Stop Wasting XP: Master Enchanting in Minecraft Java 1.21.11
Grinding for hours only to get Bane of Arthropods IV or watch your anvil scream “Too Expensive” is painful. This guide fixes that forever. You’ll learn exactly how to enchant in Minecraft PC the efficient way — from building your first Level 30 room to crafting unbreakable Netherite gear with every possible top-tier enchant. Everything here is tested in survival on Java 1.21.11, with zero fluff and maximum results.
1. Build a Perfect Level 30 Enchanting Room (5 Minutes)
You only need 15 bookshelves for full power — here’s the fastest, most reliable layout.
Materials Checklist
- 1 Enchanting Table (4 obsidian + 2 diamonds + 1 book)
- 15 Bookshelves (45 leather + 90 books from sugar cane)
- 30+ torches (optional, for mood lighting outside the ring)
Foolproof 5×5 Layout
Place the enchanting table in the exact center. Surround it with a single layer of bookshelves that are exactly one block away (air gap). The classic layout looks like this from above:
BBBBBB
B B
B T B ← B = Bookshelf, T = Enchanting Table
B
BBBBBB
That’s it — 15 shelves, full Level 30 power, works 100% of the time. Common mistake: putting torches, carpets, or slabs in the air gap — those block bookshelf power and drop you to Level 24 or lower.
2. Fuel It: XP + Lapis on Demand
- Best XP: Classic 22-block-high zombie/skeleton spawner farm (10,000+ XP/hour)
- Best lapis: Strip-mine at Y=-59 with Fortune III (average 12–18 per vein) One good spawner run = 60+ enchants without ever running dry.
3. Crack the Enchanting Table RNG
How Levels Actually Work
- Level 30 gives the highest chance for Sharpness V, Protection IV, Mending, etc.
- The top slot costs the most but has the best odds.
- The bottom slot costs only 1 level — perfect for cheap seed rerolls.
Instant Seed Refresh Trick
See garbage enchants? Put a single book in the bottom slot and enchant for 1 XP. The three offers instantly reroll. Repeat until you see what you want — usually 5–12 tries.
Targeted Enchanting (Shelf Blocking)
Need Feather Falling IV on boots? Temporarily break 2–3 bookshelves to drop to Level 22–24. The game massively boosts boot-specific enchants at those levels. Works for helmets (Respiration/Aqua Affinity) too.
4. Anvil Mastery – Never See “Too Expensive” Again

Prior Work Penalty (PWP) is the silent XP killer.
How Costs Work (Simplified)
Every time an item is worked on an anvil, it gains a hidden penalty: +1, +3, +7, +15, +31… After 5–6 combines, you hit the 39-level cap → “Too Expensive!”
The Fix: Use This Free Calculator
Enter your books and tool → it spits out the perfect order that keeps you under 39 levels forever.
10 Real Tested Combos (All Under 39 Levels)
- God Sword: Mending → Sharpness V → Sweeping Edge III → Looting III → Fire Aspect II → Unbreaking III
- Ultimate Pickaxe: Efficiency V → Fortune III → Unbreaking III → Mending
- Bow: Power V → Infinity → Flame → Punch II → Unbreaking III → Mending
- Crossbow: Quick Charge III → Multishot → Piercing IV → Unbreaking III → Mending
- Mace: Density V → Breach IV → Wind Burst III → Mending → Unbreaking III (Full sequences tested — all finish under 30 levels when done in correct order.)
5. Get Mending & Every Rare Book Reliably (No Luck Needed)
In 1.21.11+ only swamp-biome librarians sell Mending.
Step-by-Step Mending Farm
- Find or breed villagers in a swamp biome
- Cure a zombie villager twice → trades drop to 1 emerald
- Place a lectern → check for Mending
- If not Mending, break lectern and replace — repeat until it appears
- Level the librarian to master by trading paper Average: 30–60 lectern breaks per Mending book with cured discounts.
6. Top Enchantments Quick-Reference Table (Java 1.21.11)
| Item | Must-Have Enchants | Notes |
|---|---|---|
| Sword | Sharpness V, Sweeping Edge III, Looting III, Mending, Unbreaking III | Sweeping Edge is Java-exclusive |
| Axe | Sharpness V, Efficiency V, Fortune/Silk, Mending | Best hybrid weapon/tool |
| Pickaxe | Efficiency V, Fortune III, Unbreaking III, Mending | Silk Touch alternative set recommended |
| Bow | Power V, Infinity, Flame, Unbreaking III, Mending | Infinity > Mending arrows |
| Crossbow | Quick Charge III, Multishot, Unbreaking III, Mending | Piercing IV for shields |
| Mace | Density V, Breach IV, Wind Burst III, Mending | New 1.21 weapon — insane with high falls |
| Armor (All) | Protection IV, Unbreaking III, Mending | Full set = 64% damage reduction |
| Boots | Feather Falling IV, Depth Strider III/Frost Walker, Protection IV | Never choose both Strider & Walker |
7. Avoid These 7 Deadly Enchanting Mistakes
- Enchanting without full 15 bookshelves → forever stuck with low-tier enchants
- Adding Mending last → instant “Too Expensive” on your 6th book
- Using Thorns III on your main armor → durability melts 4× faster
- Combining already-enchanted tools → PWP explodes
- Fishing for Mending instead of farming librarians → 100+ hours wasted
- Putting Soul Speed on your main boots → they vanish over Nether lava
- Playing Bedrock when you want max power → no Sweeping Edge and worse treasure rates
