Key takeaways
- Flight duration is set by how many pieces of gunpowder go in the recipe – one, two or three – and nothing else changes it.
- Rockets with firework stars deal damage when they explode, which is the only way to make a crossbow fire explosives.
- A duration-one rocket is the right choice for elytra flight; longer rockets waste gunpowder and overshoot.
Firework rockets are two completely different items wearing the same name. One is the elytra fuel that every player burns by the stack. The other is a crossbow munition that most players have never crafted. They share a recipe and almost nothing else.
This guide separates them – how duration actually works, why the cheapest rocket is the right one for flying, and what a firework star does to a crossbow.
The base recipe
A firework rocket is paper plus gunpowder. That is the whole requirement:
- 1 paper + 1 gunpowder = 3 rockets, flight duration 1
- 1 paper + 2 gunpowder = 3 rockets, flight duration 2
- 1 paper + 3 gunpowder = 3 rockets, flight duration 3
Three rockets per craft regardless. The gunpowder count sets the duration and nothing else. Three is the maximum – there is no duration 4.
Paper comes from sugar cane, which is the cheapest renewable material in the game. Our sugar cane farm guide covers automating that side, and once it is running paper stops being a consideration entirely.
Gunpowder is the real cost. It comes from creepers, ghasts and witches, and a creeper farm is the standard answer. Our spawn-proofing guide covers building one that produces at a useful rate.
Why duration 1 is correct for flying
This is the single most common waste of resources in the late game, and the reasoning is simple once you see it.
A rocket used with an elytra provides thrust for its duration. Longer duration means more thrust, which means more speed and more distance per rocket. That sounds strictly better.
It is not, for three reasons:
Gunpowder cost scales linearly, distance does not. A duration-3 rocket costs three times the gunpowder for roughly two to two and a half times the distance, depending on your angle. Per unit of gunpowder, duration 1 travels further.
Control granularity. With duration-1 rockets you adjust your flight every second or so. With duration-3 you commit to three seconds of thrust, which is how people fly into cliffs. Precision matters more than top speed on anything other than a long straight crossing.
Firework damage on hit. If you are carrying rockets with stars for any reason and mix them up, a longer rocket in your hand while flying is worse.
The exception is a long, straight, unobstructed crossing at high altitude, where duration 3 genuinely saves time. For everything else, craft duration 1 and craft a lot of it. Our elytra guide covers the flying technique that makes rockets last longer regardless of duration.
Firework stars
A firework star is the effect payload. Crafted from gunpowder plus a dye, with optional modifiers:
- Shape: fire charge for a large ball, gold nugget for a star shape, feather for a burst, head for a creeper shape. No modifier gives a small ball.
- Dye: sets the colour. Multiple dyes give multiple colours in one star.
- Glowstone dust: adds twinkle.
- Diamond: adds trail.
Adding a star to a rocket recipe makes the rocket explode with that effect. Up to seven stars can go in one rocket. Fade colours are added by crafting a finished star with additional dye.
For decoration this is all there is to it. For combat, one line matters more than all of the above.
Rockets as a weapon
A firework rocket containing at least one firework star deals damage when it explodes. A rocket with no star does not.
That turns a crossbow into an explosive launcher. Load a star rocket into a crossbow, fire it, and it detonates on impact or at the end of its flight, damaging everything in a small radius.
Practical notes:
- Damage scales with the number of stars in the rocket, up to seven.
- It damages you too if you fire it at your feet, exactly as you would expect.
- Multishot on a crossbow fires three rockets at once, which multiplies the damage and the gunpowder cost equally.
- It does not break blocks. This is explosion damage to entities only.
Where this is genuinely useful is against grouped mobs – a raid wave, a mob farm overflow, a cluster in a dungeon. Our raid guide covers the fight where this matters most, and our combat mechanics explainer covers why an area weapon changes the maths against a group.
The cost is the thing. A seven-star rocket is seven gunpowder plus seven dyes plus the rocket’s own gunpowder, for one shot. This is a boss-fight or raid tool, not a standard loadout.
Using rockets while flying as a weapon
Related but distinct: holding a star rocket and using it for elytra thrust detonates it on you. Do not do this. The rocket you fly with must have no stars in it, which is another reason to keep your flight rockets as plain duration-1 and store them separately from decorative ones.
A labelled shulker box solves this permanently. Our shulker box guide covers naming and colour-coding, and this is a good use case for it.
What to keep stocked
For a working base, three stacks:
- Duration 1, no stars. Flight fuel. Craft these by the hundred once a creeper farm is running.
- Duration 3, no stars. A small stack for long ocean or Nether crossings.
- Star rockets. Half a stack at most, kept for raids. Make them before you need them, because crafting under pressure is how you end up with the wrong rocket in your hand.
Decorative rockets are their own thing and worth making for a server event or a build reveal – a dispenser firing coloured rockets on a redstone clock is the cheapest spectacle in the game. Our server events guide covers where that fits, and our redstone basics covers the clock.
