The World Boss, introduced in Update 28, is a mode where the player fights a powerful boss for WB Coins and its card. It can be accessed with jjk worldboss.
Pressing "Start" uses the attempt, even if the player loses, so be careful! Fights last up to 100 turns, and if time runs out, the team with the higher HP % wins.
Rewards are only given if the player wins. Every win gives 40 to 70 WB Coins, and each boss has its own EXP and card drop.
Note: The player can hold up to 9,999 WB Coins.
| Boss | Available | HP |
|---|---|---|
| Weekly rotation | 10M | |
| Weekly rotation | 10M | |
| Weekly rotation | 400M | |
| Gjallarnhorn, and weekly rotation during its event | 400M |
The boss changes every week, and the current boss is shown under "Stage Mechanics" in jjk worldboss. Any boss on this list, including The Perfected Being vs. The Perfect Curse, can also be fought at any time by using a Gjallarnhorn.
The Perfected Being is immune to the last Element that hit it, and Unfavourable Elements deal double damage. Grounded stops this and makes it take 15% more damage (30% from Pirates). King of Curses cards deal 100% more damage in this fight.
The shop can be accessed with jjk wb shop, and the prices are in WB Coins. It sells the items of the boss currently in rotation, so each shop below is only open while its boss is the weekly boss.
