11Ferocious Horn Den is an Expedition dungeon in AION 2, called 사나운 뿔 암굴 in Korean. The English name used here is the one carried by the game client's English data; NCsoft has not used it in an English announcement as of October 2, 2026. The dungeon was among the Conquest dungeons running in the first week of the Korean and Taiwanese service in November 2025.22As of October 2, 2026, NCsoft has not published which Expedition dungeons are open in the global build that launches on October 5, 2026. Everything on this page describes the Korean and Taiwanese service unless it says otherwise.3+Global service: the global client's game data, as of its September 18, 2026 snapshot, contains Ferocious Horn Den with Exploration and Conquest modes, but NCsoft has not published the global Expedition roster as of October 7, 2026. Everything else on this page describes the Korean and Taiwanese service.44At a Glance6+DetailValue (KR/TW)Korean name사나운 뿔 암굴TypeExpedition: Exploration, Conquest Normal and Conquest HardPartyUp to five players (four before July 1, 2026)Cost40 Odyle Energy for Exploration since April 8, 2026BossesWatchdog Kwapo, Necromancer Duanka, Ferocious Horn NuakumKinaBound on Conquest Normal (July 1, 2026) and Conquest Hard (August 26, 2026)Draconic materialsBound only, since September 9, 202658Modes and Timeline69ChangeDate (KR/TW)Conquest Hard addedDecember 24, 2025Exploration cost set to 40 Odyle Energy, rewards raised, three-clear bonus addedApril 8, 2026Half of Conquest Kina paid as bound KinaApril 8, 2026Conquest Normal Kina bound in fullJuly 1, 2026Conquest Hard Kina bound in fullAugust 26, 2026Draconic materials bound onlySeptember 9, 2026811Bosses912OrderBossKorean nameNotesFirstWatchdog Kwapo번견 쿠하푸At 75% and 25% health scatters orbs and ends with a ring that must be jumped; its dash and claw frequency was eased on January 14, 2026SecondNecromancer Duanka강령술사 두안카Summons four adds it can absorb to heal; a white orb in the room lets one player damage themFinalFerocious Horn Nuakum사나운 뿔 누아쿰Passive bleed stacks make positioning matter from the first hit1114Barricades on the route are broken with bombs picked up from chests. English boss names come from the game client's English data.1215Boss Mechanics17+Community strategy guides on the Korean service describe a route with four encounters: Watchdog Kwapo, a Shining Mau Totem (빛나는 라이칸 토템) gimmick fight, Necromancer Duanka and Ferocious Horn Nuakum. The totem had to be destroyed to pass the Altar of Requiem (진혼의 제단) door; a January 7, 2026 fix stopped players walking through without breaking it.19+BossHow the fight worksWatchdog KwapoMoves to the centre and scatters damage zones and lightning orbs; players soak every orb, each of which slows them, because on the second howl a purple ring detonates any orb left behindShining Mau TotemActivating it spawns adds and bomb crates; it fires homing missiles at everyone and cannot be broken until the adds are deadNecromancer DuankaSpins his staff and drops explosions on every player; raises Lycan sentinel souls that only players holding the altar's green orb can destroy, and that heal him if they reach him; his Soul Caller pull drags everyone to the centre among converging lightning orbs before a large blastFerocious Horn NuakumHis hits stack a debuff that drops damage pools; claws to the front; in the clone pattern ("the prey has been chosen") a random player is rooted and clones charge at them, so other players body-block each clone without taking two in a row; at low health Blue Light of Destruction (파괴의 푸른 빛) clears the pools and the party must land red balls in the central energy1321Abyssal Horn Den1422The Chapter 1. Lands of Sand and Snow update tells what happened next. In the lore of Abyssal Horn Den, the Ferocious Horn Den was pulled into the Abyss, and the cave that remained fell to the exile Gargaum, who gained the power of the primal Lycans. Abyssal Horn Den reuses the layout with tougher bosses as a four-stage Transcendence dungeon.1624Related Pages1826Expedition Dungeons for the tier as a wholeDungeons for every instance in the gameOdyle Energy for the entry and reward currency
