Learn the encounter before your next pull. This guide is an original English synthesis of reviewed YouTube captions and official Korean mode rules. Follow the specific difficulty and source version shown below.
Mechanic instructions follow the cited gameplay explanation. HP percentages identify approximate phase triggers, not a guaranteed attack timeline.
Entry, difficulty & preparation
Use bombs to break the starting barricades. Gather everyone before activating the totem room: the room locks, and bomb boxes help clear its enemy waves. Open checkpoints along the route.
| Check | What to use |
|---|---|
| Mode covered | Normal & Hard |
| Group | Up to 5 — current Korean party format |
| Entry requirements | Select this dungeon and difficulty in the entry panel. Check character level, item level, minimum party size and remaining entries there. The reviewed mechanic videos do not establish a current numeric admission threshold. |
| Before pulling | Agree assignments, activate available checkpoints, clear pursuing enemies and prepare movement, defensive and stagger skills. |

Watchdog Quapo
Agree which side to clear before the jumping phase. You need usable floor for the landing as well as for the shockwave.
| Tell / phase | Your response | Why it matters |
|---|---|---|
| Thunder Cry, around 75% / 25% | Collect small blue orbs to clear a safe area; jump the shockwave when the boss lands. | Uncollected orbs explode over large areas. |
| Chasing purple orbs | Move away from their detonation circles. | These are hazards, unlike the small collectible blue orbs. |
| Large spread marker on tank | Keep other players out. | Additional bodies increase the damage. |

Necromancer Dunka
Assign a backup soul killer in case the primary player is immobilized. The buff is what enables the add assignment.
| Tell / phase | Your response | Why it matters |
|---|---|---|
| Soul adds around 75% / 50% / 15% | Assigned player collects the white orb in the north and kills the adds before the absorption cast finishes. | Remaining souls heal and strengthen the boss. |
| Soul Caller pull around 65% / 30% | Run beyond the indicated area while avoiding incoming stun orbs. | Damage increases with proximity; staying near the centre can kill you. |
| Bound player in shared-damage pool | Join the target and heal through the shared damage while respecting other attacks. | The pool is intended to be shared, not abandoned. |

Ferocious Horn Nuakum
Gather in clean floor before the clone phase, agree the interception order and name a backup. Do not confuse the small stack with the large spread marker.
| Tell / phase | Your response | Why it matters |
|---|---|---|
| Three bleed stacks / expiry timer | Place the resulting blood pool along the edge. | The source’s bleed cannot be cleansed; floor control matters. |
| Clone phase around 75% / 55% | One player intercepts the clone before it hits the bound target; others stack for the small marker or separate for the large marker. | The dash and the stack/spread are simultaneous jobs. |
| Repeated clone dashes | Rotate interceptors rather than letting one player take every hit. | The interception debuff makes repeated soaking dangerous. |
| Blue Light of Destruction around 30% | Marked target lines up boss → central orb → player. Repeat successful interceptions three times. | Failing to break the orb before the cast completes wipes the group. |
| Bound target after orb phase | Two different teammates intercept the successive projectiles. | The bound target cannot safely take the direct hit. |

Difficulty changes & encounter details
Hard adds an explosion with fear where a clone disappears. Move out promptly after resolving stack/spread. This guide is also cross-checked against FRESHY’s September overview.

Tank, healer & DPS assignments
Strategy recommendationSuggested preparation for this encounter. These assignments are editorial recommendations based on the mechanics above.
| Role | Assignment |
|---|---|
| Tank | Keep blood pools away from future gathering spots; join the interceptor rotation. |
| Healer / support | Prepare sustained healing for Dunka’s shared pool and recovery between clone interceptions. |
| DPS | Assign a soul killer, rotate interceptors and do not tunnel damage through the central-orb check. |

After a wipe: fix the cause
Strategy recommendationName the failed mechanic before the next pull. Check whether the target moved too early, the group missed its assignment, or a required cooldown was unavailable. Reassign a backup for any job that can target its original owner. Surviving the mechanic comes before completing a damage rotation.
- Call the next mechanic before the HP threshold; the actual cast may occur later.
- If a hit-count object is involved, use fast direct hits rather than assuming a long damage cooldown is better.
- Save burst for a real vulnerability window after the group has completed its movement.
- Check the current entry panel for loot probabilities and reward availability before spending another run.
