Skill Trees in Sailor Piece let you permanently boost your stats by spending Skill Points. This system unlocks at level 7000 and requires significant grinding to max out all branches. Each skill tree focuses on different stats like damage, health, critical hits, and luck. Here's every skill tree in Sailor Piece, how to unlock the system, and the fastest way to farm Skill Points.
All Skill Trees in Sailor Piece
Sailor Piece has five skill trees, each with five upgrade levels. You must unlock levels in order - you can't skip to level 3 without buying levels 1 and 2 first. Here are all skill trees with their costs and stat boosts:
| Skill Tree | Level 1 | Level 2 | Level 3 | Level 4 | Level 5 | Total Boost |
|---|---|---|---|---|---|---|
| Damage% | 3 SP (+5% damage) | 6 SP (+5% damage) | 10 SP (+5% damage) | 15 SP (+5% damage) | 25 SP (+5% damage) | +25% damage |
| HP% | 2 SP (+7.5% HP) | 5 SP (+7.5% HP) | 8 SP (+7.5% HP) | 13 SP (+7.5% HP) | 20 SP (+7.5% HP) | +37.5% HP |
| Crit Chance | 3 SP (+1% crit) | 6 SP (+1% crit) | 10 SP (+1% crit) | 15 SP (+1% crit) | 25 SP (+1% crit) | +5% crit chance |
| Crit Damage | 3 SP (+3% crit damage) | 6 SP (+3% crit damage) | 10 SP (+3% crit damage) | 15 SP (+3% crit damage) | 25 SP (+3% crit damage) | +15% crit damage |
| Luck | 15 SP (+5% luck) | 25 SP (+5% luck) | 50 SP (+5% luck) | 75 SP (+5% luck) | 100 SP (+5% luck) | +25% luck |
- Damage% increases your overall damage output from all sources. This affects melee fighting styles, swords, and Devil Fruit abilities equally. Maxing this tree gives you 25% more damage, making it one of the most important trees for offense.
- HP% boosts your maximum health by 7.5% per level. The total 37.5% health increase helps you survive longer during boss fights and PvP. This tree is less important than damage early on but becomes valuable for endgame content.
- Crit Chance raises your probability of landing critical hits by 1% per level. Critical hits deal extra damage, so higher crit chance means more burst damage overall. The 5% total boost might seem small but adds up over long fights.
- Crit Damage increases how much extra damage your critical hits deal. Each level gives 3% more crit damage for a total of 15%. This tree synergizes with Crit Chance - you want both maxed to get the most benefit from critical strikes.
- Luck improves drop rates for rare items throughout the game. Each level gives 5% more luck, capping at 25% total. This is the most expensive tree by far, requiring 265 total Skill Points to max compared to 59 points for Damage%.
How to Unlock Skill Tree in Sailor Piece
You need to meet two requirements before accessing the Skill Tree system. First, reach level 7000 or higher. Second, collect 1000 gems through quests, codes, or boss farming. Once you have both requirements, travel to Slime Island using the island portal. After spawning on the island, find the Skill Tree NPC inside one of the huts. This NPC wears a black outfit with a hat. Talk to the Skill Tree NPC and submit your 1000 gems to unlock the system permanently.
After unlocking, you can return to this NPC anytime to spend Skill Points on upgrading your skill trees. The skill tree interface doesn't appear in your menu - you must visit the NPC on Slime Island every time you want to allocate points.
How to Get Skill Points in Sailor Piece
You earn 1 Skill Point for every 250 enemies defeated in Sailor Piece. This counter includes both regular mobs and bosses, but regular mobs are far more efficient for farming. Bosses count as single enemies but take much longer to defeat than regular mobs. Killing 250 regular mobs is significantly faster than defeating 250 bosses.
Turn on auto skill and stand near the mob spawn points. Your character automatically attacks enemies as they respawn, letting you farm Skill Points passively. This works best in areas where mobs spawn frequently without long delays.
Maxing all five skill trees requires 324 total Skill Points. That translates to defeating 81,000 enemies total. The grind is massive, so start farming Skill Points as soon as you unlock the system at level 7000. Prioritize Damage% first since it helps you kill enemies faster, which speeds up farming for more Skill Points. For more Sailor Piece guides, check out our Sailor Piece wiki.
