Mavuika
Kazuha
Bennett
Xilonen
Kazuha groups spores → Mavuika detonates all → Bennett buffs → Xilonen shreds RES
Alternative Option
Mavuika
Kazuha
Bennett
Durin
If Xilonen unavailable, Durin provides extra off-field pressure.
Phase Strategy
Phase 1
DO NOT attack the boss directly. Use Kazuha to group all 16 spores together. Let Mavuika's Pyro application detonate them simultaneously.
Phase 2
Boss enters Vulnerable State (0% RES). Unleash ALL abilities and bursts. Bennett's ATK buff + 0% RES = massive damage. 15 seconds of burst DPS.
Pro Tips
- The Vulnerable State deals more damage in 10 seconds than 5 minutes of normal attacking.
- Patience in Phase 1 = faster clear.
- Kazuha's grouping is critical - all 16 spores must be together for simultaneous detonation.
