Aion 2 Ferocious Horn Den Exploration: Entry Requirements and Rewards

The Ferocious Horn Den sits at the end of the level 45 Expedition track in Aion 2, a party dungeon buried in the Abyss and home to the Ferocious Horn Mau tribe. It runs in two flavors, Exploration and Conquest, on the same map and boss roster. Conquest raises enemy health and damage and adds a few extra wrinkles, and its item-level 86 Unique armor is what pushes most players toward the 2,800 gear score needed for the Ludra raid.

Quick answer: Enter at level 45 with 1–5 players at 2,100 item level, then beat Watchdog Kwapo, destroy the Shining Mau Totem, down Necromancer Duanka, and kill Ferocious Horn Nuakum inside the 60-minute limit.

Ferocious Horn Den entry requirements

Both modes share the same level floor, party size, and timer. All four bosses are level 63. Run Exploration a few times first to learn the pathing before you move to Conquest, since traversal is identical between them.

For Conquest, aim for at least 100k to 110k Combat Power on top of the 2,100 gear score. Conquest also carries a 5-minute enrage timer on Nuakum, while Exploration has none.

Route through the den

Boss mechanics

Watchdog Kwapo

At 75 percent and 25 percent health, Kwapo becomes invulnerable and jumps around the arena, leaving small lightning AoEs and blue orbs behind. It follows with Thunder Cry, which has a 12-second countdown. Walk over the orbs before the cast finishes to remove them; any still on the floor detonate when Thunder Cry resolves, dealing heavy burst damage as an expanding ring moves outward. Clear the orbs along one flank to create a safe lane, then jump over the ring as it sweeps by. Kwapo lands on the player who had the last aggro afterward.

Two filler attacks matter. Kwapo summons three purple balls that track a random ally and explode on contact, so keep moving to peel them off. It also drops a red circle with arrows pointing outward on one player, meaning everyone else must get out of the ring. Damage scales with how many bodies are inside. Learn this arrow rule now, because the final boss reuses it.

Necromancer Duanka

At 75, 50, and 15 percent health, Duanka casts Mau Necromancy, summoning four tethered ghosts on the edges of the room for roughly 15 seconds. If they reach the boss, it absorbs them, heals, and stacks buffs. One player, ideally a DPS, grabs the green orb on the north side of the room for a speed and damage buff that lets them hurt the ghosts, then wipes out all four quickly while the tank and healer hold position.

At 65 and 30 percent health, Duanka draws the entire party into the center and begins Soul Caller, which hits harder at close range. Leave the red zone before the cast finishes, avoiding the lightning orbs that stun and immobilize players. Duanka also places a red circle with inward-pointing arrows on one player and creates a blue puddle that drains health. Have the whole group stack in the marker to share the damage. Other attacks include a health-draining blue line and various AoEs that can be dodged.

Ferocious Horn Nuakum

Almost every hit Nuakum lands applies a non-cleansable bleed stack (Prey). At three stacks a 4-second timer runs out and a lingering blood pool forms under the target. These pools stack up across the fight, so drop them at the arena edge to keep the center clean. The tank bleeds fastest and should manage this carefully.

At 75 and 55 percent health, Nuakum jumps out of the arena and leaves blue orbs, marks an ally, then sends a clone dashing toward that target. An unmarked player must intercept the clone’s path to stop its dash and bring Nuakum back. The blocker receives a debuff, so assign a different player for each one. Check the marked ally’s circle during the mechanic: arrows pointing outward call for spreading out, while inward arrows mean everyone should stack. Once the clone resolves, move away from the following point-blank AoE. On Hard, the clone also causes fear after resolving.

When Nuakum drops to 30% health, a compact energy orb appears in the room’s center and begins the 34-second Blue Light of Destruction wipe cast. It draws players toward its position and burns those within a 6-meter radius. Nuakum marks one player, who must align with the boss with the orb directly between them so his thrown projectiles hit it. The orb breaks after three hits, and Nuakum throws four times. He fears the party before his third throw, so stay near the orb without entering its burn radius. If the cast completes, it deals damage to the entire room equal to 500% of max HP.

Later, Nuakum roots one player and throws two red balls along a straight path. Each ball needs a separate unmarked player to intercept it, because the debuff prevents one person from taking both. His other attacks are a ground-scratching frontal flurry (get behind him), a reach that stuns and pulls, a charge along a wide lane, a pounce circle, a knockdown AoE, expanding donut rings, and a roar that fears everything within 30 meters.

Odyle Energy and the guaranteed Nuakum piece

Spend Odyle Energy on the reward cube at the end of a run. It regenerates over time, up to 560, or 840 with a membership. Opening the Odyle Energy Cube takes 40 Odyle Energy; selecting a guaranteed Nuakum armor piece from the menu costs 80.

Pick your guaranteed piece before the run starts from the selection screen. The options are the Nuakum Breastplate, Greaves, Helm, Pauldrons, Gloves, Boots, and Cloak, all Unique grade. Every Nuakum piece is tier 2 Unique at item level 86, usable from level 45, with four manastone slots, a +15 enchant ceiling, and a 55,000 Kina sell price.

Each of these sits third in Defense within its own slot. The Breastplate’s 637 trails only the 756 on the Splendent Ebony and Splendent Wise Dragon Lord Breastplate, the Greaves’ 531 trails the 630 Dragon Lord Greaves, and the Helm’s 477 trails the 567 Dragon Lord Helm.

Loot and Epic drop rates

The den has 76 obtainable items in total. The cube hands out item-level 86 Unique Nuakum armor, item-level 45 blue Black Claw weapons and armor, and item-level 30 green Earth and Vagabond gear, plus a Unique Artwork and Unique Wings. Materials in the pool include Refining Stones up to Artisan’s Ultimate grade, Enhance Stones, Balaur’s Essence, Amplify Stone Fragments, Soul Codex, and Silentium. A clear’s guaranteed drops include a Soul Codex, Silentium, 140,000 Kina, and 2,000 Enhance Stones.

Every boss can drop the Epic Black Claw set and the Fera Necklace. The drop rates from Nuakum are roughly twice those of the first two bosses, making the final fight the fastest place to collect the set.

Epic item	Kwapo	Duanka	Nuakum
Black Claw Ring	5.7%	5.7%	12.2%
Black Claw Gloves	4.3%	4.3%	9.2%
Black Claw Cloak	4.3%	4.3%	9.2%

A pity box becomes available after 21 cube openings and grants either an armor piece or a Gear Change Voucher, so even a long dry streak eventually earns a reward.

Confirming the clear

Defeating Ferocious Horn Nuakum brings the run to an end. A banner reading Expedition Complete appears, loot is placed on the arena floor, and the Odyle Energy Cube becomes available for spending energy and claiming rewards. A death-free Exploration clear earns the Ferocious Horn Den Exploration Perfect Clear achievement, one Soul Codex, and 5,000 Kina. In the harder mode, the Ferocious Horn Den Conquest Clear mission counts 10 Conquest clears toward a 500 Kina reward, giving you a reason to keep farming the den once the fight is no longer a problem.
