Adobis Zakum jump quests reward for EXP has been removed due to fly-hackers. They are relatively simple top-to-bottom climbs, but they reward only closeness for a pet. They may be accessed at will and repeated whenever desired, regardless of level, you need to create a username and password. The more unique it is, the more secure. Much better if you have not used it before and solely created it for World of Warcraft Gold usage only.
A character starts at one part of a map, and uses timed jumps to get from one small platform to another, while attempting to avoid enemies and obstacles that can knock the character off of the platform, causing them to be forced to either start over from the beginning, or, if the character is lucky, from a certain point somewhere above the beginning.
