Earning Skill Points is very important in One Piece World Seeker as they allow you to unlock new techniques and abilites for Luffy. Skill Points are earned simply by playing the game and are given as rewards for everything from defeating powerful opponnents to completing missions. They are basically points which you can redeem at the 'Skills' menu to unlock new skills, attacks and attribute boosts.
The fastest way to get Skill Points in One Piece World Seeker is to complete the main missions and side missions as each of them can give you between 100 and 500 upon completion. The actual amount of Skill Points you get will ultimately depend on the the difficulty of the mission, the harder they are the more Skill Points they will yield. The main missions are straight forward and easy enough, each time you complete one a new one will become unlocked. In total there are 13 main missions you can complete before you enter the end game and this is not including the numberous side missions that also open up as you progress through the main story, all of which give you the possiblility of earning more Skill Points if you complete them.
Another way to get Skill Points fast is to farm areas that continously spawn powerful enemies when you defeat them. The Radio Tower, Emerald Town, Naval Base, Sky Islands, and Crystal Canyon are places worth considering for this.
