Bosses

As the name implies, this game features various unique bosses for players to choose from and fight. (with more on their way!) From chaotic robots to destructive elementals, there's an endless variety of bosses to fight. Each boss is split into tiers, tier I being the easiest, tier II being moderately difficult, and tier III being the most difficult. Event bosses and minigame bosses are exempt from the tiers, as they are not able to be classified in a tier. Each boss is also listed with a difficulty. Difficulties go in this order from easiest to hardest: Easy, Medium, Hard, Difficult, Challenging, Insane, Impossible. The full difficulty chart can be found here.

Tier I
Tier I bosses are the easiest bosses available to fight. There is a slight "theme" to this tier, as all the bosses are 'artificially-made' such as robots. They pose little challenge to most players, and can even be beaten solo if you have at least some experience with their attacks. They can be fought by entering the green portal.

Tier II
Tier II bosses are a significant step in difficulty from Tier I. They are moderately hard, posing a much bigger challenge to players. It's recommended to fight these bosses with a team. They can be fought by entering the yellow portal.

Tier III
Tier III bosses are the most difficult bosses in the game, and will put up a significant challenge. These bosses are borderline impossible to defeat alone, and almost 100% require a team. They can be fought by entering the purple portal.

Special Bosses
"Special Bosses" are bosses that can't be classified into any specific tier and are fought through other means. This includes bosses accessed through minigames, and secret bosses.

Event Bosses
Event Bosses can only be fought during certain events. (Halloween, Christmas, etc.) Currently, no event bosses have released yet.
