Zodi-yak Track is an event which allows players to earn rewards by completing tasks, which started on 23 March 2020 and ended on 3 May 2020. It featured two prize tracks, free and premium, the latter of which gave a larger number of prizes. Players could unlock the premium track by having an active Premier Club membership or by buying a Premier Pass using two bonds.

Players can complete either task to progress to the next tier. Task requirements are based on the player's level in the task skill, as well as if they are free-to-play or pay-to-play. Free-to-play players only have the options of free-to-play skills as tasks, whilst members have a mixture of free-to-play and members skills. New to the Zodi-yak Track are joint tasks; these tasks show two skills in a single task choice, and actions from either skill will progress the task.

Players can skip tiers by using task skips. Everyone initially has two task skip tokens (independent of unused skips from a previous yak track), and more can be purchased with bonds via the store.

Despite the task wording saying 'and above', not all items that require a higher level than the one listed are eligible to complete the tasks. All eligible items could be found by selecting the 'info' button next to the task in the Yak Track Task List.

The following table uses requirements (both the amount, and item required) as based on a maxed player. For non-maxed, and further item details, see the requirements section below. Not all people will have the same tasks.

The number and exact nature of things that must be done to complete a task depend on the player's skill levels.
