World Boss is server wide boss that is unlocked after completing a Dimensional Rift once. Clearing the World Boss for the first time unlocks the Rift of Worlds. The World Boss respawns 6 hours after it has been defeated. Players can only participate three times per day even if the world boss respawns on the same day.

10-20 monsters can selected to attack the world boss on each attempt. Once a monster has been used in a World Boss Battle, it cannot be used in another World Boss Battle until the day resets. The World Boss is a community wide event, where every player's attack deals accumulated damage to the world boss. The World boss is defeated once the boss's HP is reduced to zero.

After every battle, the player is graded from F to SSS depending on the total damage dealt. The amount of damage a monster deals is calculated based on how well the monster is "trained", which depends on a variety of factors. A set amount of random grade rewards are given depending on the grade. When a world boss is defeated, the total damage each player has dealt is tallied up and the clearance reward will be sent out.

Monster selectionEdit

Players can bring 10-20 monsters to battle the world boss with each attempt. Monsters must be at least level 30 to participate, and once a monster has been used it cannot be used again until the day resets. Friend rep monsters cannot be used to battle the world boss.


The actual battle is an auto battle where a cinematic clip is shown with the selected monsters attacking the boss. Players do not have any control over their monsters' actions. World boss battles do not give any Experience.

The amount of damage a monster deals is based on how well the monster has been "trained". The amount of "training" depends on a number of factors, such as the monster grade, level, and the amount of skill-ups it has received, runes equipped, etc. A higher number in the monster's stats and level will increase "training" value. Runes influence damage where a higher rune grade and upgrade amount increases the training of a monster. The monster training will be converted into battle power which will determine the monster's damage dealt to the boss.

Additionally, the world boss has two attributes (eg. water & fire). Bringing monsters with elements that are strong against those attributes will also result in more damage against the boss.

Battle GradingEdit

The possible rewards given after each battle depends on your grade and are random, i.e. you can get repeated rewards.
