| Encounter Phase | Boss HP Threshold | Key Hazards & Abilities | Recommended Counter-Play |
|---|---|---|---|
| Phase 1: Shadow Vanguard | 100% – 70% HP | High-speed shadow wolves and infantry swarm the main path. | Deploy Madaro or Goju early at the first bend for broad AoE slow and bleed. |

| Phase 3: Blood Frenzy Enrage | 30% – 0% HP | Boss movement speed triples; physical defense rises by +50%. | Trigger True Damage units (Overseer Cursed Lover) and max-IV single-target carries. |

World Boss FAQ
What is the best way to farm Fusion Cores in Anime Origins?+
Fusion Cores come from World Boss drops and the World Boss Shop. They are the clean alternative to sacrificing duplicate summons — farm World Bosses to star up Secret and Mythic units safely. Always buy Fusion Cores first in the World Boss Shop.
How do you beat the Igris World Boss solo in Anime Origins?+
Igris throws constant AoE stuns (up to ~30s) and buffs the fodder. Run a double-heal shell (Vegeta or Roxy) plus stun-proof carries like Gojo or Anigo, bring Anak for the clash phase and Jeter for raw damage, and avoid Ban whose AoE radius is too small for the wave phases.
