Bane of Arthropods is a Minecraft weapon enchantment that makes your attacks much stronger only against arthropod mobs like spiders, cave spiders, bees, silverfish, and endermites.

What Bane of Arthropods Actually Does

  • Increases damage to arthropod mobs (spiders, cave spiders, bees, silverfish, endermites) and does nothing extra to other mobs like zombies or skeletons.
  • Each level (I–V) adds extra damage only when you hit those arthropods.
  • It can be put on swords and axes as a combat enchantment.

A simple example: hitting a spider with a Bane of Arthropods V sword will deal noticeably more damage than the same sword without the enchantment, but hitting a zombie will be unchanged.

Damage Numbers (How Strong Is It?)

Different sources describe the scaling slightly differently, but they agree that damage increases with each level and only on arthropods.

Typical description:

  • Level I: noticeable bonus damage to arthropods.
  • Level V: very high bonus damage to arthropods, enough to kill weaker ones in far fewer hits.

The official-style breakdown describes it as a fixed extra damage per level applied only to arthropods.

Extra Effect: Slowness Debuff

On top of the bonus damage, Bane of Arthropods also applies a strong Slowness effect to arthropods you hit.

  • Applies Slowness IV to arthropod mobs when struck.
  • Duration is random in a small range and gets longer as the enchantment level increases (from roughly around 1 second at level I up to around 3.5 seconds at level V).

This means spiders and similar mobs move much slower for a short time after you hit them, making fights safer.

When You Should Use It

Bane of Arthropods is situational but powerful in the right context.

Best use cases:

  • Exploring mineshafts full of cave spiders.
  • Clearing strongholds with lots of silverfish.
  • Farming spiders or bees for drops.

In those scenarios, a Bane of Arthropods sword or axe can shred through mobs very quickly and keep them slowed so they can’t swarm you as easily.

How It Compares to Other Enchantments

Common alternatives on swords/axes are Sharpness and Smite.

Enchantment What it boosts Best use
Bane of Arthropods Extra damage + Slowness to spiders, cave spiders, bees, silverfish, endermites only.Spider/cave spider farms, mineshafts, silverfish areas.
Sharpness General extra damage to almost all mobs.All‑purpose combat weapon.
Smite Extra damage to undead (zombies, skeletons, etc.).Wither fights, undead farms.
Because it’s so specialized, many players only use Bane of Arthropods on a dedicated “spider‑killer” weapon and keep Sharpness or Smite on their main weapon.

Forum & Trending Context

The question “bane of arthropods what does it do” keeps popping up on forums because many players pull it from an enchantment table and aren’t sure if it’s worth keeping compared to Sharpness. Some guides from 2024–2026 frame it as underrated: it’s weak as a general enchant, but extremely strong if you’re focusing on arthropod-heavy areas or farms.

You’ll also see people recommending combinations like Bane of Arthropods + Looting + Fire Aspect on a dedicated sword just for spiders and silverfish, since this melts them fast and improves drops.

Quick TL;DR

  • Bane of Arthropods = extra damage only to spiders, cave spiders, bees, silverfish, and endermites.
  • Also adds a short Slowness IV debuff to those mobs when hit.
  • Great for spider/silverfish-heavy areas, not good as a general-purpose enchant.

“If you’re always in caves fighting spiders, it feels amazing. If you’re doing everything else, Sharpness is better” – common community sentiment reflected in recent guides and discussions.
