Tool Details and Use Cases
Damage Calculator
The Damage Calculator lets you input your current stat totals (Melee, Sword, Fruit, Gun, Defense) along with your race, equipped accessory, and rune level, then outputs the expected damage for each of your abilities — both with and without Haki activation. This tool is most useful when you are deciding between two different stat distributions at the same total level. For example, if you have 5,000 points to allocate, the calculator shows whether splitting 3,000 Sword / 2,000 Melee outperforms a pure 5,000 Sword build for your specific fighting style. All damage formulas are updated after each major patch.
Open Damage Calculator →Build Optimizer
The Build Optimizer takes your current gear as input — race, fighting style, accessory, and rune — and suggests the optimal stat allocation for your chosen goal (PvP burst, boss farming, mob clearing, or survivability). Rather than manually calculating damage scaling curves, you select the gear you already own and the playstyle you want, and the tool returns a recommended percentage split across all five stat categories. The optimizer also flags which upgrades would have the largest impact on your output: for instance, switching from a B-tier rune to Havoc Rune, or rerolling from a common race to SwordBlessed for a sword-focused build.
Open Build Optimizer →Level Tracker
The Level Tracker estimates how long it will take to reach your target level based on your current XP per hour rate, active Double XP boosts, race XP bonuses (e.g. Fishman), and the island you are grinding on. Enter your current level and XP rate, toggle any active bonuses, and the tracker returns an estimated time-to-target in hours and a recommended grinding location for your current level range. The tracker covers all progression stages from Lv1 to the current cap of 11,500 and is updated whenever new islands or XP rebalances are patched in.
Open Level Tracker →Price Guide
The Price Guide lists current community trade values for all tradeable items in Sailor Piece: Devil Fruits, accessories, rare drops, and dungeon materials. Values are sourced from community trading channels and updated weekly. The guide is most useful before trading or purchasing items from other players, as in-game prices fluctuate significantly after major patches — for example, Havoc Rune and Manipulator Outfit values typically spike in the days following a new update. Each item entry includes the current price range, a 7-day trend indicator, and notes on supply changes from recent patches.
