Once you have the game installed (mobile or PC) you have to understand several things.

The first 4 menus are about:
1-. Daily: These are specific daily or monthly missions. Here you can also train your character to obtain fragments and make medals that enhance certain skills.
2-. The Characters/Reinforcements menu: Here you can find all the characters, both unlocked and locked.
3-. In the Market menu: you can buy character fragments in exchange for game items, you can also buy improvements or items for your characters.
4-. Recruitment: Here you can directly roll a roulette wheel for random characters (there is a table that specifies the % of obtaining each character), either through gems or tickets.

Events Menu:
The event menu is constantly updated and it is important that you check it every time you enter the game. They often give out gems or valuable/necessary items for the game.

At the top right, there are 4 icons.-
In the first one we will find the Clan menu.
The second icon is the in-game store, where you can buy passes, gems, and even characters.
In the third icon is the gift box which is where all the rewards you earn arrive.

Lastly, there is the combat menu: where there is both PVP and PVE:
in the first menu:
We meet the Challenge Combat:
We can find both PvE and PvP, we can have to fight against bosses as a team or fight against other players (either just combat or taking flags). It depends on the event, it usually lasts for weeks and the rewards are usually good.



In the second section we find the League Combat.Here, unlike the "Challenge Battle", there is only PVP, and it is the same as most games that have ranked or competitive battles.

In the third section, you will find the "individual" menu.
Here you can farm gems through fights related to the One Piece story, following the entire plot. And in the 2 remaining menus you can farm XP and in-game coins, you have 2 daily opportunities if you can't use a token.
