Koi Fish Scales are a resource found lodged in the floor of the Pond Depths and harvested with a shovel. They also have a chance drop from the Koi Fish when attacking it with any weapon, however it is difficult to obtain them this way. They are primarily used to make Koi Scale Armor. Once harvested, Koi Fish Scales take 3 in-game days to respawn. Those found as loot in the Pond Lab and Lab Outposts do not respawn.
