How to get Diamonds in One Piece Grand Arena?
Diamonds are the all-important currency in the One Piece Grand Arena. Here's how to get a bunch of them!

To unlock new character skills and level them up in One Piece Grand Arena, you must use the Gasha machine, manned by Franky. The diamonds go into the Gasha machine and new character skills roll out. Sometimes, you’ll get duplicates too, but don't worry - they are just as handy. With enough dupes, you can awaken your character’s skill and max out their power levels.
That makes diamonds an absolute necessity if you want to become King of the Pirates. Luckily, there are quite a few ways to get diamonds in One Piece Grand Arena and this short guide explains all of them in detail.
