The best sword enchantments in Minecraft are not a top-ten list — they're one real decision (Sharpness, Smite, or Bane) and a set of picks that are simply always correct. Get the combination right and a netherite sword one-crits a creeper and pays for its own upkeep in drops.
This guide gives you the exact damage numbers on Java 26.2, the case for carrying two swords instead of arguing about one, and the anvil order that gets all five enchantments on without hitting "Too Expensive".
Every sword enchantment at a glance
| Enchantment | Max | What it does | From the table? |
|---|---|---|---|
| Sharpness | V | +0.5 × level + 0.5 damage vs everything (+3 at V) | III–IV typical; V via anvil |
| Smite | V | +2.5 × level vs undead only (+12.5 at V) | Yes |
| Bane of Arthropods | V | +2.5 × level vs spiders/silverfish/bees + Slowness IV | Yes |
| Fire Aspect | II | 4 s of burn per level on top of the hit; cooks meat drops | Yes |
| Looting | III | +1 max drop per level, +1% rare-drop chance per level | Yes |
| Sweeping Edge | III | Sweep carries up to 75% of your damage (Java only) | Yes (Java) |
| Knockback | II | Roughly +3 blocks of knockback per level | Yes |
| Unbreaking | III | ≈4× durability | Yes |
| Mending | I | XP orbs repair 2 durability per point | No — trading, fishing, loot |
The one decision: Sharpness, Smite, or Bane
The three damage enchantments are mutually exclusive, so every sword picks one. The math settles it: a netherite sword deals 8 damage; Sharpness V takes that to 11 (16.5 on a crit), against every mob in the game. Smite V takes it to 20.5 — but only against undead: zombies, skeletons, drowned, phantoms, wither skeletons, and both boss fights' worth of the wither itself.
That means Smite V two-shots almost everything it applies to and is the single best wither-killing item in the game — and is completely ordinary the rest of the time. The answer isn't either/or: main sword Sharpness, second sword Smite, swap at the farm entrance. Bane of Arthropods has the same numbers as Smite but against spiders, silverfish, and bees — a target list too thin to spend a blade on.
Looting III pays for everything else
Looting III raises max common drops by three and rare-drop odds by 3% — wither skeleton skulls, ender pearls, tridents from drowned. Over a farm session that's the difference between one skull and a beacon setup. The mechanic to know: Looting applies if the sword is in your main hand at the moment of death, so you can fight with anything and switch to the Looting sword for the killing blow.
Fire Aspect and Sweeping Edge — the situational two
Fire Aspect II adds an 8-second burn and auto-cooks animal drops — a hunting perk and extra chip damage in PvP. The cost is chaos: burning mobs ignite you on contact and the burn finishes kills for you seconds after you disengage, which can steal the timing you wanted. Sweeping Edge III (Java only) makes the sweep attack carry up to 75% of your damage — the difference between plinking a zombie siege one at a time and actually clearing it.
What to skip
Knockback II sends targets flying out of your combo range and out of farm kill zones — good on a crowd-control stick, wrong on your main DPS sword. Bane of Arthropods is a real enchantment for a fake problem. Curse of Vanishing deletes the sword on death; keep cursed loot out of your anvil chain entirely.
Getting the books and the anvil order
Everything except Mending rolls on a level-30 enchanting table; Sharpness V comes from combining two IVs, and Mending comes from a lectern-rerolled librarian. The anvil rule is the same one from our bow guide: merge books pairwise first (Sharpness IV + IV → V, Looting III + Unbreaking III, Mending + Sweeping Edge III), then apply the merged books to the sword in as few operations as possible — each operation on the sword doubles the hidden prior-work penalty, and 39 levels is the hard ceiling.

Common mistakes
- Smite on the only sword. The +12.5 evaporates the moment a creeper walks up — creepers aren't undead.
- Looting in the offhand. It does nothing there — main hand at the kill, or no bonus.
- Fire Aspect at the mob grinder. Burn kills still drop loot, but flaming zombies igniting each other despawns the neat one-hit rhythm.
- Applying books one at a time. Prior-work penalty doubles per operation — merge pairs first or the last book costs 40+ levels.
