Boss compendium
Every boss the datamine flags for traditional MapleStory Classic, in level order. Cross-referenced with combat stats, spawn maps, and drop tables. Each entry pairs the raw dossier data with editorial notes on access, strategy, and threat level.
Live at Grand Launch Nexon's Grand Launch release notes list Mano, Stumpy, Mushmom, Shade, Zombie Mushmom, and Jr. Balrog; King Slime is the Kerning City Party Quest finale.
Mano
Victoria Island mini-boss
The first boss most characters meet. Lv 20 with 7,420 HP in the Classic World client - almost four times the 2,000 HP of traditional MapleStory - so a solo Lv 20 fight takes a real potion budget. Spawns in Thicket Around the Beach III.

Perion field boss
New on the Grand Launch roster. Lv 35, 19,220 HP, and 276 EXP in the Classic World client, in Parched Land off East Rocky Mountain V near Perion. The Perion quest 'Monstrous Tree Stumpy' (Lv 34+) asks you to defeat him once.

Lv 40, 34,440 HP, and 340 EXP in the Classic World client (traditional MapleStory had her at Lv 60 with 20,000 HP). Spawns in Someone Else's House. Community-reported drops are led by Ilbi Throwing Stars, plus Mushmom Spores, Elixirs, and crafting catalysts.

sleepywood dungeon boss
Lv 80 with 325,400 HP and 2,188 EXP in the Classic World client - not the Lv 55, 30,000 HP boss of traditional MapleStory. He waits in The Cursed Sanctuary and is the hardest live boss on the roster by a wide margin.
