Mine Mine no Mi : All Fruits All Boxes
On 1.20.1 this addon is not needed any more. AkumaLib does the same thing with one setting, and it puts the fruits of every addon in the boxes too. This page stays for 1.16.5 where the addon still works.
On 1.20.1 use AkumaLib
Install AkumaLib 4.3.0 or newer and set this in akumalib-server.toml
[devilFruitBoxes]
fruitBoxMode = "MIXED"
The file is in the serverconfig folder of your world. Put a copy in defaultconfigs so every new world has it. An operator can also change it while the game runs with /akumalib fruitboxes mode mixed.
Every fruit then has the same chance in every box, like with this addon. If you want the rare fruits to stay rare set fruitBoxKeepWeights = true in the same place.
On 1.16.5
Nothing change, the addon still works. Take it in the Files tab, it needs Mine Mine no Mi for 1.16.5.
Every Devil Fruit box, wooden iron or golden, can give any fruit with the same chance. A wooden box found on a starter island can have the Gura Gura no Mi or the Mera Mera no Mi inside.
