Assistant Cheng's one quest requires riding conveyor belts and dodging Trixters. Adobis' quest puts the jumping over a pit of lava, with rocks falling from the ceiling. Jump quests can be done again and again to receive random ores and jewels each time, except Adobis' quest which always rewards EXP and a quest item(Maple Story Meso) on completion. Adobis' Zakum jump quest's reward for EXP has been removed due to fly-hackers. There are also two unofficial quests in the Pet Parks located in Henesys and Ludibrium in Maplestory.
They are relatively simple top-to-bottom climbs, but they reward only closeness for a pet (2 in Henesys, 4 in Ludibrium). They may be accessed at will and repeated whenever desired, regardless of level(Maplestory powerleveling). Speed and Jump boosts, along with movement skills such as Flash Jump and Teleport do not work in any Jump Quest. A Fighter/Page's Power Guard does work however. It will reduce the knock back damage done from a monster.
