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 Phantom Summon Generator

  1. Type phantom into the search box, or select it from the Hostile group in the dropdown.
  2. Set Size to any whole number from -1 up to 64. This generator defaults to 0, matching how every naturally-spawned phantom always starts.
  3. Use the shared fields above the panel – Health, Glowing, No AI, and the rest – for anything else.
  4. Copy the finished /summon command into a command block, server console, or operator chat.

Command Syntax & NBT Reference

Base command: /summon minecraft:phantom ~ ~ ~ {NBT}. The Size field maps to:

  • Size:<n> – unlike a slime or magma cube, every naturally-spawned phantom is always Size 0 – there’s no natural variation. This field only matters if you deliberately want a bigger phantom via /summon or this generator; the range this tool accepts is -1 to 64.
  • Phantoms always have a flat 20 HP regardless of Size – Size scales its wingspan and the damage it deals per hit, not its own health pool, which is a key difference from slime/magma cube sizing.

Because size doesn’t affect a phantom’s own health, using the shared Health field on this page alongside a large Size value is the way to build a genuinely tougher, harder-hitting boss-style phantom rather than relying on Size alone.

Frequently Asked Questions

Why do naturally-spawned phantoms only ever have Size 0?

Size scaling on phantoms exists purely as an NBT option for commands and other spawning methods – the game’s natural insomnia-based spawning logic always creates phantoms at Size 0 with no exceptions, so any bigger phantom you encounter was necessarily summoned or spawned through a command or a data pack, not organically.

Does summoning a phantom this way trigger it near sleepless players automatically?

No – the insomnia mechanic (spawning phantoms above a player who hasn’t slept in 3 in-game days) is a separate, automatic spawning system entirely unrelated to this generator. A phantom summoned here appears immediately wherever you run the command, regardless of anyone’s sleep timer.

Do I need to sleep to stop phantoms I summon with this generator?

No – sleeping in a bed resets the real insomnia timer that controls natural phantom spawns, but it has no effect on phantoms already summoned via command. A summoned phantom sticks around and behaves normally until it’s killed or naturally despawns, independent of anyone’s sleep schedule.

How much extra damage does a bigger Size actually add?

A phantom’s attack damage scales as a base amount plus its Size value, so increasing Size directly raises how much damage each swoop attack deals on top of the mob’s default hit – useful for building a noticeably harder phantom encounter without touching any other NBT field.
