Ferocious 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.
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.

Order | Boss | Korean name | Notes |
|---|---|---|---|
First | Watchdog Kwapo | 번견 쿠하푸 | At 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, 2026 |
Second | Necromancer Duanka | 강령술사 두안카 | Summons four adds it can absorb to heal; a white orb in the room lets one player damage them |
Final | Ferocious Horn Nuakum | 사나운 뿔 누아쿰 | Passive bleed stacks make positioning matter from the first hit |
Barricades on the route are broken with bombs picked up from chests. English boss names come from the game client's English data.
Boss Mechanics
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.
Boss | How the fight works |
|---|---|
Watchdog Kwapo | Moves 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 behind |
Shining Mau Totem | Activating it spawns adds and bomb crates; it fires homing missiles at everyone and cannot be broken until the adds are dead |
Necromancer Duanka | Spins 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 blast |
Ferocious Horn Nuakum | His 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 energy |
Abyssal Horn Den
The 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.
