The Boss Time notice.
Boss Time is a period similar to Danger Modes when the players have to fight a single, harder enemy. The Boss Time alert is accompanied with a voice saying "Ladies and gentlemen, it's showtime!". Boss rounds last for 1 minute , and will automatically end if the boss is successfully defeated. (With the exception of Hyper bosses)
The bosses only appear by themselves, unlike other enemies, which spawn in multitudes. Bosses usually have their own attacks and, as a result, are more dangerous than regular enemies. They also have more HP, which means they are harder to kill. If the players do manage to succeed in taking down the boss, however, they are able to reap great rewards.
In hardcore, like other disasters, they are replaced with their Hyper counterpart. Bosses without Hyper counterpart will not make an appearance in Hardcore. In addition, Reaper and Black Mage becomes 'Superbosses'.
Superboss
As mentioned, Reaper and Black Mage will now appear as 'Superboss' in Hardcore. Their 'Boss Time' warning color changed from light blue to purple-red. They appear as Hyper counterpart like hardcore bosses. The difference of Superbosses and hardcore bosses is the duration. Hardcore bosses last for 60 seconds while Superbosses last for 150 second. They also receive a much larger amount of HP. The said factors make Superboss harder compared to hardcore bosses.
