This MapleStory Classic bosses guide covers the five challenge bosses Nexon's Founder's Access release notes list as live at launch, plus the Kerning City Party Quest, which ends in a boss fight of its own. Here is what is confirmed about each.
The five launch bosses
- Mano
- Mushmom
- Shade
- Zombie Mushmom
- Jr. Balrog
Nexon's notes name all five as part of the Founder's Access launch content but do not publish per-boss level recommendations or drop tables; treat any specific numbers you see elsewhere as unconfirmed until Nexon or the in-game boss panel states them. New characters following the leveling guide reach a safe level for these fights well before they run out of earlier content.
Kerning City Party Quest: King Slime
Characters level 21 and above can queue for the "First Time Together" Kerning City Party Quest, where a party solves puzzles, fights its way through monsters and finishes against King Slime. Because of heavy traffic on channels 1 and 2, Nexon limited the party quest to channels 3 through 6. By level 21 you have long since finished second job advancement, so bring whichever of the ten classes you picked at level 30.
Crafting and Citizenship, if you want gear before a boss run
Crafting opens at level 10 across six crafting NPCs (Smithing, Weaponcrafting, Tailoring, Woodcrafting, Leatherworking and Arcforge), and Citizenship opens at level 12 for Henesys and Kerning City, giving shop discounts and access to local specialty items. Neither system is boss-specific, but both are available well before you are ready for Kerning City Party Quest or the five launch bosses. If you are new to the game, start with the beginner guide before hunting any of them, and check the release date guide for what else is live between Founder's Access and the Grand Launch.
