Hoolay’s primary threat comes from his devastating damage output that can quickly overwhelm unprepared teams. When he transitions into the Eclipse Ire State (commonly called Moon Rage), players face a critical DPS check – you must land multiple attacks rapidly to completely shatter his Toughness bar in one sequence. Failing this check triggers his signature Lupin Chase Calls Bloody Gleam ability, which delivers catastrophic single-target damage capable of instantly eliminating any character.

The encounter’s complexity escalates through periodic Wolftrooper summons that create additional battlefield pressure. These reinforcements not only attack your party but also increase Hoolay’s chances of winning the clash during Moon Rage phases. Managing these adds becomes progressively more challenging as the fight continues.

Phase 2 introduces a significant mechanical shift that catches many players off-guard. Unlike the first phase where successful out-attacking instantly breaks toughness, the second phase requires players to deplete toughness through conventional means. This change demands adaptive strategy and often requires team adjustments mid-fight.

Common Strategic Mistakes: Many players underestimate the importance of action economy and bring single-target specialists who cannot handle the multi-hit requirements. Another frequent error is prioritizing raw damage over survivability, leading to team wipes during the intensified Moon Rage sequences.

Building the right team composition is the single most important factor for overcoming Hoolay’s challenges. Your character selections must address multiple combat requirements simultaneously while maintaining balance between offense and defense.

Elemental Advantage Priority: Your primary damage dealers should possess Wind, Physical, or Fire damage types to exploit Hoolay’s specific weaknesses. Since Hunt March 7th is automatically included in story missions, optimize her skill usage by targeting main DPS characters with these elemental alignments. Characters who can inflict direct Toughness damage regardless of element provide valuable flexibility for teams lacking ideal coverage.

Multi-attack Specialists: Characters capable of executing follow-up attacks shine exceptionally bright in this encounter. Their ability to deliver multiple hits in quick succession makes them ideal for breaking Moon Rage states efficiently. Support units that provide action advance effects also deliver tremendous value by increasing your team’s action economy.

Sustain Requirements: Given Hoolay’s relentless assault and Wolftrooper reinforcements, your sustain characters must provide multi-target healing or shielding capabilities. Single-target healers will struggle to keep pace with the incoming damage spread across your entire team.

Advanced Optimization Tactics: For players seeking to maximize performance, consider timing your ultimate abilities to coincide with Moon Rage transitions. Building energy reserves before these phases ensures you can unleash the necessary multi-hit sequences when they matter most. Positioning also plays a crucial role – keeping your sustain character safe from targeted attacks prevents catastrophic team collapses.

Action Checklist

  • Verify your main DPS has Wind, Physical, or Fire damage type
  • Include at least one follow-up attack specialist or action-advance support
  • Ensure sustain character provides multi-target healing/shielding
  • Save ultimate abilities for Moon Rage phase transitions
  • Adapt strategy for Phase 2 toughness breaking mechanics
