how to turn off fireworks? They make it very difficult to play. I recommend turning this feature off by default.

What version of minecraft are you playing?

Fireworks are Perks, which can be configured in minecraft/saves/<yoursave>/serverconfig/pmmo-perks.toml

an example of what to add/remove for a firework looks like

[[Perks.For_Event.SKILL_UP]]
    skill = "fishing"
    perk = "pmmo:fireworks"

Each skill that should have fireworks should have a section like this in the config.

To remove a firework from a particular skill, delete/comment-out the firework perk section from the config.

Make sure to only edit this file while the game is closed, and avoid using Notepad++

В яку версію minecraft ти граєш?

1.20.1

Thank you

Can I do this not for a specific world? Because I often create new worlds.

Once you edit the pmmo-Perks.toml file, put it in the minecraft/defaultconfigs/ folder. Whenever you make a new world from now on, it will use that version of the file.

Ok
