Featured Challenge Overview
Boss Mechanics
Critical Mechanic
Boss spawns IMMUNE to Slow and Stun.
You must first break the boss's armor (or trigger a state change) before crowd control effects work. This is why Kenpachi is essential - his armor penetration helps break this immunity.
Pre-Boss
Economy build-up and positioning
Place Speed Cart immediately. Start building DPS. Position Virtual Idol to cover all units.
Boss Spawn
Break armor before using CC
Boss spawns immune to Slow and Stun. Must break armor/trigger state change before CC works.
DPS Phase
Full burst with debuffs
Once boss is vulnerable: Kenpachi Vulnerability (+15%) + Virtual Idol buffs. Unload all damage.
Solo vs Multiplayer
| Factor | Solo | Duo+ | Impact |
|---|---|---|---|
| Boss HP Scaling | ~150 HP | ~200 HP | More players = tankier boss |
| Kill Credit | All kills are yours | Kills may be stolen | Sun Jin Wu needs kills for mana - bad in MP |
| Coordination | Full control | Need good teamwork | Random teammates can sabotage |
Recommendation: Solo may be easier if you have strong units. Sun Jin Wu specifically performs worse in multiplayer due to kill credit mechanics (he needs kills for mana).

Ragna Farming Reality Check
The Math
- • Drop rate: 2% per clear
- • Pity: Guaranteed at 75 clears
- • Full E6 Ragna: Needs 7 copies
- • Worst case: 75 × 7 = 525 clears
- • Cannot AFK: Each run requires active play
Verdict: Farm for rerolls and the occasional Ragna drop. Don't expect to E6 Ragna without extreme dedication. Many players consider this grind unreasonable.
