How to clear it

Recommended approach

Hahnul is the launch endgame dungeon boss — Lightning element, weak to Fire, recommended level 60. HP sits at ~1,695,800 (24× Custos) with boss ATK climbing to 1,872 and stagger gauge to ~36,060 (groggy DEF 925). This is the launch capstone fight: every system in the game — gear, stagger, Affliction stacking, survival — needs to be running together to clear cleanly. The fight also drops the Hahnul's Roar SSR Fire set, the namesake of this boss, used by your Fire team for every subsequent endgame Conquest.

Fire element is the only efficient elemental answer. Mina (SSR Fire Brawler) leads via Essence stacks + Luminous Rush burst. Flare (SSR Fire Destroyer) provides Blaze Zone + Dragon's Breath sustained damage. Leeho (SR Fire Slayer) chips Prey Mark + Tiger Hunter burst windows. Verna (SR Fire Brawler) is the simpler F2P alternative with Fire conversion BA chains. Angel (SR Fire Slayer ranged) auto-procs Support Skill on teammate crits — good off-field amp for Mina-led teams.

Pull-priority for this fight: Mina + Flare define the entire Fire endgame curve. Without either, Verna / Leeho / Angel still clear at recommended level but the fight stretches to ~6-7 minutes. The Hahnul's Roar 4pc drop is the meta-defining loot — every Fire team needs it for sustained endgame Conquest. Plan to farm Hahnul repeatedly once you can clear.

  • Story / first clearCLaunch endgame capstone. Equipment ~Lv58+ + meta Fire team required for clean clear.
  • Conquest ticketsSDrops the Hahnul's Roar SSR Fire set namesake — primary farm for the entire Fire endgame meta.
  • SpeedrunD1.7M HP + 36k stagger means sub-5-minute clears require Mina C2+ AND Flare C2+ with full Hahnul's Roar 4pc.
  • F2P difficultyDHard F2P. SR-only Fire comp (Leeho + Verna + Angel + Francis) clears but expects ~7+ minute fights and Equipment ~Lv60+.
  • Reroll filterSIf Hahnul walls you long-term, reroll for Mina or Flare. Fire core defines the entire endgame Conquest curve from here onward.

Stagger windows

  • Drops the Hahnul's Roar SSR Fire set — the meta-defining loot for every Fire endgame team. Repeating Hahnul is the entire launch endgame farm loop.
  • Single weakness (Fire) — clean elemental matchup, no element-locked phase shifts.
  • 10 HP phases — multiple stagger windows over a long fight, recovery-friendly with proper sustain.
  • Groggy DEF 925 — burst windows still convert cleanly during stagger; Mina Luminous Rush + Flare Dragon's Breath both pay off.
  • Fire Affliction from Mina / Flare / Leeho / Verna compounds via Hahnul's Roar 4pc (+10% Crit DMG vs Fire-Afflicted) — entire team's damage scales together.
  • Lightning-element boss → reduced Lightning damage from Hahnul's attacks on Lightning-resistant gear (Spirit King 4pc, Ice Heart 2pc).

Boss threats

  • 1.7M HP — 24× Custos. The launch attrition ceiling, ~4-5 minute clears with a fully geared Fire team.
  • Boss ATK 1,872 — second-hardest one-shot threat in the launch progression. Survival comp + healer + Equipment ~Lv58+ mandatory.
  • Stagger gauge ~36,060 + groggy DEF 925 — single-Special stagger breaks unrealistic, plan for 6-7 cycles per phase.
  • Without Mina or Flare, the fight stretches to ~6-7 minutes — SR-only Fire teams clear but feel grindy.
  • Fire-only elemental answer — Wind / Lightning / Ice / Earth carries deal neutral damage with no efficient amp.
  • Highest gear demand of the launch progression — Equipment ~Lv58+ realistic clear threshold, expect multiple Conquest tier attempts before clean clears.
How to clear it

Recommended team

Best counter carry, best team comp, and farmable alternates to clear Hahnul.

BIS counter carryBISMina (Fire Brawler)SSR Fire Brawler. Essence stacks + Luminous Rush burst loop. Blazing Kumiho signature artifact converts her Essence build-up into compounding Fire damage. The cleanest single-character clear of Hahnul at C0 once Equipment ~Lv58+ + Hahnul's Roar 4pc reached.
Best team compBISMina + Flare + FrancisLaunch Fire core. Mina leads with Essence burst, Flare anchors sustained Blaze Zone + Dragon's Breath, Francis covers reactive heal + Earth Affliction (wasted on Hahnul Lightning resist but heal is the key value). The default endgame comp for Hahnul — works at every Conquest tier with proper gear scaling.

Alt team comps

  • Mina + Leeho + Francis (single-target focus) — Mina leads, Leeho Prey Mark + Tiger Hunter charged-BA burst, Francis healer. Single-target heavy — faster individual phase clears but slower overall versus Flare's AoE Blaze Zone. Pick if your gear favours single-target.
  • Flare + Verna + Francis (F2P-leaning) — Flare leads, Verna's simpler Fire conversion + BA chains chip secondary damage, Francis healer. Pure-Flare-led comp for players without Mina. Slower than Mina + Flare but still endgame-viable.
  • Verna + Leeho + Angel + Francis (SR-only) — Pure-SR Fire team. Verna BA chains lead, Leeho Tiger Hunter burst, Angel off-field auto-proc amp, Francis heal. F2P endgame option — ~6-7 minute clears at recommended level, expects Equipment ~Lv60+.

Boss rotation

Suggested clear rotation

Fire core rotation — Mina leads burst, Flare sustains, Francis anchors survival.

  • 1. Tag-In with Francis for heal + Earth Affliction (wasted but heal counts) — Open with Francis Tag-In — Earth Affliction is wasted on Hahnul (Lightning resist) but the Drug Field heal anchors team survival from the start. Establishes the heal field.
  • 2. Swap to Flare for Blaze Zone + sustained Fire DMG — Flare's BA + Special chains drop the Blaze Zone — sustained Fire ground damage that ticks throughout the fight. Builds Mina's burst window via Fire Affliction uptime for Hahnul's Roar 4pc payoff.
  • 3. Swap to Mina for Essence stack + Luminous Rush burst — Mina's BA combo builds Essence stacks; Special / Luminous Rush at full Essence dumps the highest single-instance Fire damage in the launch roster. Primary stagger contributor + burst window opener.
  • 4. Trigger stagger → dump Luminous Rush + Dragon's Breath — Stagger breaks after 6-7 Special cycles. During BIND window, dump Mina's Luminous Rush at full Essence + Flare's Dragon's Breath Ult. Highest single-instance damage of the fight.
  • 5. Repeat — Hahnul has 10 HP phases — 1.7M HP / 10 phases = ~170k per phase. Each phase opens fresh stagger gauge after 10s recovery. Pace the fight around 6-7 stagger cycles per phase + Francis auto-heal at 75% HP. Equipment ~Lv58+ keeps the rhythm sustainable for a ~4-5 minute clear.

Quick answers

FAQ

What is the recommended level for Hahnul?
Recommended level 60. Equipment level ~Lv58+ is the realistic clear threshold. Below that, the 1.7M HP + boss ATK 1,872 make the fight feel attritional and dangerous. The launch endgame capstone fight.
What element should I use against Hahnul?
Fire. Hahnul is Lightning element and weak to Fire — every Fire attack deals bonus damage. Lightning attacks are wasted (Hahnul IS Lightning); Wind / Earth / Ice deal neutral damage. Build the team around Mina / Flare / Leeho / Verna / Angel.
Can I clear Hahnul F2P?
Yes, but very slowly. Pure-SR Fire team (Verna + Leeho + Angel + Francis) clears at recommended level but expects ~6-7 minute fights and Equipment ~Lv60+. The fight is the F2P endgame ceiling — pulling Mina or Flare significantly accelerates clear time.
How much HP does Hahnul have?
~1,695,800 HP at level 60. 24× Custos at the same launch-progression pace — the launch attrition ceiling. Fight typically ends in ~4-5 minutes with Mina + Flare + Hahnul's Roar 4pc, ~6-7 minutes with SR-only Fire.
How do I survive Hahnul's high ATK?
Boss ATK 1,872 — second-hardest one-shot threat in the launch progression. Bring Francis (reactive Drug Field heal) as the survival anchor. Equipment ~Lv58+ HP / DEF substats on Mina + Flare keep them alive through the burst windows. Avoid glass-cannon builds without sustain.
Which character is best against Hahnul?
Mina (SSR Fire Brawler) is the cleanest single-carry clear via Essence + Luminous Rush burst. Flare (SSR Fire Destroyer) anchors sustained Blaze Zone DMG. Leeho (SR Fire Slayer) provides single-target burst. Mina + Flare + Francis is the launch endgame Fire core.
What does Hahnul drop?
The Hahnul's Roar SSR Fire set — the meta-defining loot for every Fire endgame team. 2pc +10% Fire DMG on Ult, 4pc +10% Crit DMG vs Fire-Afflicted. Repeatable via Conquest tickets — farm Hahnul repeatedly to gear up Mina / Flare / Leeho / Verna with full 4pc.
Why is the boss named the same as the Fire set?
Hahnul's Roar (the SSR Fire set) is literally the loot dropped by Hahnul (the boss). The set's bonuses (Fire DMG on Ult, Crit DMG vs Fire-Afflicted) are designed around the Fire-Affliction stacking gameplay the fight demands. Killing Hahnul = farming the set named after him. Mongil sticks to this naming pattern across multiple boss → set drops.
Does Hahnul have phases?
10 HP phases. Each phase opens a fresh stagger gauge that resets after recovery (10s if not broken). 1.7M HP / 10 phases = ~170k per phase — pace the fight around 6-7 stagger cycles per phase + maintain Fire Affliction uptime for Hahnul's Roar 4pc compound damage.
Can I use my Lightning core (Penny + Reina + Benjamin) on Hahnul?
No. Hahnul IS Lightning element — Lightning attacks are wasted (Lightning-resist). Worse, Hahnul's Lightning damage output (boss ATK 1,872) one-shots glass-cannon Lightning Brawlers. Build or pull Fire before attempting Hahnul past Conquest tier 1.
