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 an armor-break unit such as Kenpachi/Berserker is strongly recommended.
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 | Lower | Scales upward | Exact HP scaling is still guide logic until run logs are captured |
| 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. Kill-credit and mana-scaling notes are strategy guidance until repeatable multiplayer logs are recorded.
Recommended Team
Fortunate: +20% income, 1% listed rate
Strongly recommended for boss phase
Buffer identity is canonical; relic priority is guide logic
Boss support recommendation remains guide logic
Use your best carry with current gear
CC timing should wait for armor-break state
Minimum Requirements
- Level 70+ Units
Your carry and key supports should be max level
- Mythic Relics
5-substat relics with relevant stats (Cooldown, Damage, etc.)
- Good Traits
Examples: Fortunate on Speed Cart/Fastcart (Likely), Duelist on Kyito/Kriatu, or a damage trait on your carry.
- Armor Break Unit
Kenpachi/Berserker strongly recommended for boss phase
Ragna Farming Reality Check
The Math
- • Current Trello drop record: Dragon Guy 3% (50 Pity)
- • Legacy summon-model claim: 2%, Guaranteed at 75 clears
- • Full E6 Ragna: 7 copies in the legacy planning model
- • Worst-case planning estimate: 50 × 7 = 350 clears if the current pity record applies
- • Cannot AFK: Each run requires active play
Verdict: Farm for rerolls and the occasional Ragna drop. Don't treat max-copy planning numbers as confirmed unless the drop/pity record is rechecked in-game.
