Overview
Stats are a mechanic in Grand Piece Online. While maximum HP and Stamina will raise by themselves as the user levels up, certain features require special attention in the form of skill points, which can be allocated into several categories that can be accessed through the Menu (M). The player gains 3 stat points every level up.
The maximum total of skill points available to the player is 1725 as of Update 8. You can find a general spreadsheet of various stat caps here.
Strength
Strength raises the damage output of physical attacks, such as Fighting Styles and non-Sword M1s, up to a certain limit. This stat does not affect damage inflicted by most Swords, Guns or Devil Fruits.
Stamina
Increases a player's stamina by 2 per stat point allocated and increases player stamina regen by +1 for every 100 points allocated. Stamina is a resource expended by the use of any attack, and is meant to regulate player aggressiveness alongside the cooldown system. The Mink race will additionally boost the player's stamina by 10%. Your stamina regen and Geppo consumption is 1% of your current stamina (if you have 1000 stamina, your stamina regen and Geppo consumption will be 10).
STA Regen = ROUND(STA/100)
Defense
Defense increases health, health regeneration and block strength. Health can be calculated by the following equation:
round-down (1.75defense + Item Bonus + Level HP) = health
Default health regeneration is 1% of your max health per second. Defense also increases the damage output of the Self Destruction skill of the Bomu Bomu no Mi.
Devil Fruit
The Devil Fruit stat unlocks the user's Devil Fruit abilities, enhances the performance and increases damage done by each Devil Fruit skill. Does not appear if the user has not eaten a Devil Fruit. You can find stats regarding most devil fruits here (feykocr55).
Gun Mastery
Increases damage dealt by Guns.
Sword Mastery
Sword Mastery unlocks sword skills, increases the damage done by all weapons categorized as Swords, and increases the damage done by the Tori Tori no Mi ability Phoenix Talons. You can find stats regarding most swords here (feykocr55).
Fighting Style Mastery
Every melee fighting style has its own unique mastery stat required to unlock skills. This stat generally does not increase the damage of fighting styles, but race-locked fighting styles such as Electro and Fishman Karate are exceptions. You can find stats regarding most fighting styles here (feykocr55).
