Spider Eggs are acquired by destroying a tier 3 Spider Den, or killing a Spider Queen. They can be planted on the ground to create a tier 1 Spider Den, which then grows like normal. The Spider Eggs can be used to relocate Spider Dens to any specific place; often an area where they can safely contain the Spiders for Silk farming. Eggs can also be used as fuel in Campfires.
- It is possible to get multiple Spider Eggs from a single Spider Den, allowing players to actively increase the number of nests in a single map.
- When removing/inserting Spider Eggs into your inventory, it makes a squelching noise.
