Best setup for farming Glass Diamond
You do not need to build around a special bait, weather window, season, or time of day for Glass Diamond. That means your setup should be focused on making repeated casts efficient and stacking as much luck as you can.
Stay inside Overgrowth Caves and stack luck instead of swapping bait or waiting for weather changes.
What Glass Diamond is used for
Glass Diamond is useful beyond bestiary completion. It is tied to the Crystalized Rod, where players use Glass Diamonds as part of the Northern Expedition pedestal interaction.
It also matters for Doug’s Great Heist, where Doug uses it among the materials connected to the Crowbar Rod. Material counts for newer quest pieces can shift or conflict early on, but Glass Diamond itself is one of the items to hold onto if you are working through that questline.
Glass Diamond mistakes to avoid
Do not farm meteors expecting Glass Diamond to drop there. Meteor farming is for other gem materials, while Glass Diamond is obtained by fishing in Overgrowth Caves.
Also avoid leaving Northern Expedition too early. The starting camp is Northern Summit; you still need to climb one level higher and actually enter Overgrowth Caves before starting the farm.
