Description

To craft flight duration 4 rockets, add 4 gunpowders to the recipe:

3 Flight Duration 4 Rockets

Or you could go with the max duration (for a single craft):

3 Flight Duration 8 Rockets

It also works with a Firework Star:

3 Flight Duration 4 Rockets With A Firework Star

This mod also adds a recipe to upgrade an existing Firework Rocket to get a higher flight duration:

3 Flight Duration 4 Rockets From Upgrading Flight Duration 3

(Crafted with 3 flight duration 3 rockets)

But also, you can craft with 1 rocket and it will add 3 flight duration!

Flight Duration 6 Rocket From Upgrade Flight Duration 3

(Crafted with 1 flight duration 3 rocket)

Since 1 gunpowder can make 3 flight duration 1 rockets, meaning 1 gunpowder will have 3 flight duration

If you craft 1 rocket with 1 gunpowder, you will get flight duration +3

And if you craft 3 rockets with 1 gunpowder, you will get flight duration +1 for each rocket

The limit of flight duration for all these recipes is 127 (Java byte limit)
