Achievements

The Adventures, Fish, and Daily achievements have a bonus reward if all three are completed before they refresh. The Progression and Mastery achievements build up over time and do not fresh after collecting them.

Daily Adventures
These three achievements refresh every four hours after opening the app, rather than daily. They seem to be only for collection of Artifacts in various environments. The Artifacts that must be collected are the free-floating artifacts that randomly appear, not the Dark Artifact or Mystic Artifact flags. The Daily Adventures achievement reward Adventure Tokens.

Daily Fish
These three achievements refresh every four hours after opening the app, rather than daily. The fish that must be caught may be beyond what can be caught using the player's current fishing poles or unlocked fishing locations, such as Legendary fish or fish only available from The Big Water. The Daily Fish achievements reward fish bones.

Daily
The Daily achievements may need the player to upgrade their Heroes or Pilots in order to level them up if they are already at maximum level. For Evolution achievements, it's possible to save a previously-unlocked Evolution Key to unlock this achievement without spending gems.

Progression
These progression achievements will unlock naturally by playing the game.

Mastery
These mastery achievements will unlock naturally by playing the game.
