I. Boss Background and Core Mechanisms
Identity: Ruler of the Card Castle, self-proclaimed "King of Checkers," with control over the Crown Core and the Dark People Army.
Special Mechanisms:
Soul Stomp: Locks onto the player's soul heart position, initiating a jumping stomp (area damage + stun).
Stardust Scatter: The crown gathers energy, firing a fan-shaped barrage of small star projectiles (can penetrate defenses).
Dark People Healing: When HP is below 50%, summons guards to group heal through "Healing Light."
Chessboard Traps: Randomly activates squares, triggering spike or flame attacks.
II. Team Configuration and Core Strategies
Character | Role | Core Skills/Equipment | Tactical Points |
Kris | Tank/Control | Sword and Shield Defense, Light People Guidance | Attract Boss fire, mark the crown weakness |
Susie | Main Damage Dealer | Berserk Mode, Ultimate Roar | Focus on breaking shields, interrupt healing phases |
Ralsei | Support/Healer | Ultimate Heal, Dark People Fusion | Group healing, dispel debuffs |
III. Detailed Guide
After defeating the guard attack, you will encounter the Checker King. Once the crown is put on, the checker will grow larger, becoming the terrifying Checker King. At this point, brute force output is not recommended,
1. Soul Stomp:
When the Boss raises the crown, immediately switch to Kris and use "Light People Guidance," the soul heart will show the safe area. We need to move to the edge of the safe area to avoid the high damage from the center of the stomp.
2. Stardust Scatter:
Before the projectile is fired, the Boss's crown will flash blue. At this moment, Susie initiates "Berserk Mode," using invincibility frames to pass through the barrage.
Ralsei continuously uses "Dark People Fusion" from the back, increasing the team's evasion rate by 15%.
3. Chessboard Traps:
When red squares appear on the ground, Kris triggers "Block Counter" with sword and shield, briefly paralyzing the Boss's actions.
4. Additionally, it can also heal itself.
Crown Core Exposure:
The Boss enters a berserk state, the crown hovers above its head, and at this point, all team attacks will automatically lock onto the core (critical hit rate increased by 50%). The strategy is to maintain health, while others pay attention to constantly bowing deeply. After a few turns, the crown will fall off. Also, dodge the projectile attacks.
