Raid Boss

Raid Bosses (レイドボス) are powerful Heartless which appear in Kingdom Hearts χ[chi]. They attack the hub in Daybreak Town at certain intervals and have to be defeated by the 's and rival teams to defend the town.

Story
While a Raid Boss is attacking Daybreak Town, the sky is covered by clouds of darkness.

Gameplay
The Raid Boss changes every two or three weeks. They are the main source of Lux, making them an essential target for winning the daily Team Battle (チームバトル) and weekly Union Ranking (ユニオンランキング).

The first attack on a Raid Boss is free, but further attacks require the Player to spend Battle Points (BP). The damage dealt to the Raid Boss is dependent on the BP spent, the Chain Bonus (チェインボーナス) awarded based on how many allied players have already attacked the boss, and the Keyblade Bonus (キーブレードボーナス) awarded based on using the Keyblade that the Raid Boss is weak to. The damage dealt can be multiplied by 10 by triggering the EX Card Bonus (EXカードボーナス).

Each Raid Boss is accompanied by a rarer variant that drops more valuable rewards, usually named Subspecies (亜種), which has a chance to appear when the initial Raid Boss is defeated quickly enough.
