Phantom Koi guide

Phantom Koi is gone from the game, and this entry only describes what it was. It was an Extinct fish from the Second Sea, caught around the Isle of New Beginnings with Luminous Larva during the day, in Foggy weather in Autumn. The game described a white koi with grey accents and ornate fins. It is tagged Unobtainable, so you cannot catch one today.

For a rare fish it was valuable: an average weight of 660 kg (216 to 7,156 kg) at C$14 per kg gives C$9,568, ranking 129th of 742 documented fish by value, and its max weight is 101st of 663. Base XP was 6,660.

Four other Extinct fish are documented in the same zone: Depth Drifter, Murkdrifter, Whisper Eel and Vinefish. The Adventurer's Rod was sold in the zone's waters.

Verdict: nothing to chase, but useful as a reference. If you meet one in a trade or someone's collection, its value is roughly C$9,500 at average weight, more than most fish documented in the game.
