Data Credits
Where our game data comes from.
Classic Maple Wiki
Class skill lists come from the open data of the Classic Maple Wiki contributors (repository commit 4a24a46, retrieved 2026-10-19). It is licensed under CC BY-NC-SA 4.0: you may share and adapt it with credit, for non-commercial use only, and adaptations must use the same license.
What we changed: Skill names, job tiers, and branches mapped to our class ids (3rd job skills left out); NPC locations, shop inventories, maps (monsters and exits), and quests matched to our pages by name, with map, item, NPC, and monster ids turned into names.
Some of that data was originally imported by the Classic Maple Wiki from MapleClassic Wiki contributors, also under CC BY-NC-SA 4.0.
maplestory.io
Monsters, items, maps, NPCs, and icons come from the maplestory.io API (MapleStory Classic World, build CBT2, retrieved 2026-10-18).
