The Kerning City PQ is located in (gasp) Kerning City in Maplestory, down by the sewers near the weapon shop. The way to get into the PQ is to have a party of 4 people of levels(Maplestory powerleveling) between 21-30 inclusively, and to have the leader talk to the nearby NPC 'Lakelis'. By the way, this is written from Mapleglobal, we do not know if names are different in the Europe version. If no party is already attempting to PQ, the screen will black out and you will appear inside a marshy, swampy area.
There is the possibility that some party has already gotten in – you will receive a message saying 'Some other party has already gotten in to attempt the quest'. If so, wait for them to finish, or change channels to try again. The best time for Party Questing. This is because Mapleglobal users are mostly based in America, and they tend to be asleep at this time, meaning the servers are less crowded.
KPQ is, from 25-30, at the time of writing, the fastest, most fun and most profitable method of training. We met many of our friends here and made most of our money(MapleStory Mesos). Possible rewards include:
10% scrolls for Glove/Overall DEX.
10% scrolls for Top/Bottom/Overall for DEF.
