An Implant Without a Source

Implant: Fine Furs exists in the game's item data, but no shop, loot table, or reward currently hands it out — and the Pal Surgery Table never asks for it. It's an unused leftover: you can't get it, and you don't need it.

How to Get Fine Furs Anyway

The passive this implant would unlock, Fine Furs (items sell for 3% more and cost 3% less while the Pal is in your party), is one of the default options at every Pal Surgery Table — no implant needed, just 10,000 gold per surgery. Its bigger sibling Noble (5%) does need an implant: Implant: Noble from the Arena Shop. See the implants guide for how surgery works and which implants are actually obtainable.
