MapleStory/Kerning City

Kerning City features a Party Quest for users between level 21 and 31, with a King Slime boss at the end.
 * Kerning City:This is the place where you become a thief. You must be at least level 10 and have 25 dex. This is the most urban-like town in Victoria Island, hence, its name. The little pit with sewer pipes are usually crowded with the high popularity of party quests. The middle sewer pipe leads you to a warning street leading to the dungeon.
