Build /summon commands with custom NBT for every vanilla mob — baby variants, equipment, colors, and mob-specific options.

Run /summon from an operator’s chat, a command block, or the server console. Not every internal NBT field is covered — this generates the commonly-used ones for each mob.

How to Use the Wither Skeleton Summon Generator

  1. Type wither skeleton into the search box, or select it from the Hostile group in the dropdown.
  2. Pick a sword tier from the Weapon (hand, default Stone Sword) dropdown, or leave it on “None” – the label itself notes that real wither skeletons always carry a stone sword by default, unlike a plain Skeleton which needs a weapon field set to have one.
  3. Copy the finished /summon command into a command block, server console, or operator chat.

Command Syntax & NBT Reference

Base command: /summon minecraft:wither_skeleton ~ ~ ~ {NBT}. The field on this panel maps to:

  • HandItems:[{Count:1,id:"minecraft:<sword>"},{}] – same sword-tier dropdown as the base Skeleton and Zombie entries (wood through netherite). Setting this to “None” only stops this generator from adding a hand-item tag – a wither skeleton summoned that way still carries its default stone sword, since that’s baseline vanilla equipment for the entity, identical to how a base Skeleton keeps its default bow even with “None” selected.

There’s no NBT field on this panel for the Wither effect itself – it’s applied automatically by the entity’s built-in attack, not something toggled through equipment or common fields.

Frequently Asked Questions

How long does the Wither effect last when this mob hits a player?

A hit from a wither skeleton applies the Wither status effect for 10 seconds regardless of difficulty, turning the health bar black and draining health over time. Unlike Poison, Wither can reduce a target’s health all the way to zero, so it’s genuinely lethal on its own if left untreated.

Can I stop the Wither effect from applying if I set the weapon to a different sword?

No – the Wither effect comes from the wither skeleton’s built-in attack behavior, completely independent of which sword (or no sword) it’s holding via this generator. Even an unarmed wither skeleton still inflicts Wither on a successful hit, since the effect is baked into the mob’s melee attack itself.

Is a wither skeleton summoned this way the only way to get a wither skeleton skull?

Wither skeleton skulls have a small chance to drop from any wither skeleton killed by a player, whether it was naturally spawned in a Nether fortress or summoned via this generator – there’s no difference in drop behavior based on how the mob came to exist.

What’s the difference between summoning a Wither Skeleton and the actual Wither boss here?

Wither Skeleton is a regular hostile mob found in Nether fortresses, while the Wither is a separate boss entity built from wither skeleton skulls and soul sand/soil, with its own dedicated entry elsewhere in this generator. They share a name and the Wither effect but are entirely different entities with different stats and behavior.
