Airship Crash (Lv 200+ Instance)
An airship went down over an unidentified island, and the Ymir Stone that powered it has twisted every creature there. Explore the crash site with your party, cull the corrupted swarm, and put down the source itself — then trade your salvage for the Unknown Boots gear line.
Requirements
| Base Level | 200+ |
| Party | Required (a party of one works) |
| Cooldown | Once per 3 days per character, resets at midnight WIB |
| Time limit | Until the dungeon expires (see the Memorial Dungeon window) |
The cooldown is set when the party leader forms the expedition, and only blocks forming a new one — you can always re-enter an expedition that is still running (handy if you died or logged out). Destroying the instance from the Memorial Dungeon window frees your party for a different instance, but does not refund the Airship Crash cooldown.
Getting There
The entrance is in the Dimensional Rift: NPC Dr. Dry Circle Strong at dali02 137,86 — the muscular little cupid you cannot miss. Use the Warper (Instances → Airship Crash) to land right next to him.
- Party leader: talk to Dr. Strong → Form the expedition.
- Everyone: talk to him again → Board the ship.
Next to him stands Rusbald (dali02 134,87), the salvage exchange — see Rewards.
Map 1 — The Island
You land on the crash island. It is quiet at first, but monsters flood BOTH maps once the investigation starts, so do the rescue work first.
Side objective — rescue the 5 Injured Passengers. Each one you talk to is helped once (they leave afterwards). Rescue all 5 and the final boss will spawn in its weakened form:
| Passenger | Position |
|---|---|
| 1 | 119,301 (north-west) |
| 2 | 300,320 (north-east) |
| 3 | 80,176 (west) |
| 4 | 318,192 (east) |
| 5 | 210,140 (south-center) |
Each passenger is helped once, then leaves — you can't farm the objective off a single one.
Also on the island: Frightened Resident (219,382, near your landing spot) tracks your rescue count, and the Cave Entrance guide (277,253) takes you down into the cavity (you arrive at 202,369).
Map 2 — The Cavity
You land at 202,369. The research camp is on the east side:
| NPC | Position | Role |
|---|---|---|
| Professor Daeguto | 364,363 |
Starts the investigation — monsters spawn on BOTH maps, including on top of you. |
| Graduate Student | 356,365 |
Repeatable kill quests (see below). |
| Nervous Student | 359,354 |
Explains the escape ropes and marks all of them on your minimap. |
| Ghost Zack | 373,371 |
Summons the boss for 55 Ymir Fragments. |
| Rope Pile | 362,353 |
One of 16 — right at the camp. |
Kill Quests (Graduate Student)
One quest at a time, repeatable, each completion pays EXP. Only kills made after taking the quest count — the whole party's kills count for you. A live counter floats above your head and in your chat.
| Quest | Unlocks | Reward (Base / Job EXP) |
|---|---|---|
| Cull 100 | — | 50M / 40M |
| Cull 200 | after finishing Cull 100 | 100M / 80M |
| Cull 350 | after finishing Cull 200 | 150M / 120M |
The Swarm
After the Professor's signal both maps fill up (roughly 140 monsters each, and they respawn as you cull them so the swarm never thins):
- Island: Moskillro, Rotten Tree, Melted Poring
- Cavity: Melted Poring, Grave Worm, Brain Sucker
Every creature has a 30% chance to drop a Ymir Fragment — the instance currency for everything below.
Escape Ropes
You cannot teleport inside the instance. 16 Rope Piles are scattered around the cavity — climb one to go back up to the island, or use it to leave the expedition entirely. Ask the Nervous Student to mark every rope on your minimap (yellow crosses).
The Boss
Bring 55 Ymir Fragments to Ghost Zack. He drags the source of the corruption into the light at the center of the cavity (199,198):
- Rescued all 5 passengers → Unidentified Creature (weakened)
- Skipped the rescues → Enraged Creature (full strength)
Both are MVP-class with guaranteed drops. Kill it and Rusbald opens his best stock.
Rewards
Rusbald (dali02 134,87, outside the instance) trades Ymir Fragments in a shop window:
| Item | Cost |
|---|---|
| Ymir Beads | 17 Fragments |
| Lv230 Unknown Boots Box (random 1 of 6) | 185 Fragments |
| Contaminated Card Book | 2,500 Fragments |
Unknown Boots & Ymir Beads
The box opens into one of six Unknown Boots (STR / AGI / VIT / INT / DEX / LUK). Use Ymir Beads on a pair (double-click the beads, pick the boots) to enchant them:
- Line 1 — always: Max HP +1~10% or Max SP +1~10%
- Line 2 — with luck: HP/SP Recovery +25~50%, MHP +50~1000, MSP +10~300, ASPD +1~7%, or Variable Cast Time -1~10%
Re-using beads re-rolls the enchant. It never fails and never breaks the boots.
Contaminated Card Book
The only source of this island's monster cards (Rotten Wood, Grave Worm, Brain Sucker, Moskillro, Melted Poring and friends).
Tips
- The Memorial Dungeon window (top of the screen,
/mdungeonto toggle) shows the dungeon timer and lets the party leader destroy the instance from outside — handy when you want to free the party for a different instance. Destroying never resets your entry cooldown. - Died? Get back in through Dr. Strong — re-entering a running expedition is always allowed.
- Repeat the Cull 200 quest if you are here for EXP; run rescue + boss if you are here for boots.
