Wardens are a special group of creatures that are considered playable boss creatures. Most Wardens have high HP and weight for their tier, but in turn start off with low damage which gets higher the less Hp they have while getting directly attacked thanks to their common ability, Warden's Rage.

Lore-wise, Wardens are the main deities and protectors of the world of Sonaria. They are active typically around their seasons or through the ideas they embody. Wardens cannot be seen physically by any creature except through their incarnations that roam the land. There is very little interaction among the Wardens unless there is a major event such as a mass extinction, a great natural disaster, or a soul of great fortitude. The incarnations of the Wardens resemble their originator exactly in looks, however their power is trivial to the original. Incarnations can act as the eyes of the wardens or as their physical will in the world.

As such, each Warden is usually associated with a seasonal event, and it has been confirmed that Wardens will come and go as time goes on in accordance to what event they are associated with. The only exceptions to this rule are the Hellion Warden, which is available year-round through the Time Points Shop (Time Gacha on Legacy), and Novus Warden - which was not planned to come back with its event, but was later returned. Despite this, the Novus Warden may not return a third time.

All Wardens have the highest prices in their event shop, if event has it's own shop, and even Hellion Warden, which is in the Time points shop, has the highest price.
