Although not the hardiest of creatures, spiders are the strongest insect creatures that a keeper can attract. Their abilities serve to slow or freeze opponents, making them good support units. However, they are natural enemies of Flies, and will actively fight them if sharing the same Lair. As one of the three insect creatures, Spiders are a key component for sacrifices, and due to their love of training, will give you higher level creatures as a bonus.
Spiders make poor researchers and above average manufacturers. In their free time, they like to go to Prisons and freeze inmates there.
Keeper Arachne was well known for her love of spiders, and often used an enlarge creature spell to create massive specimens the size of a house. She also sent venomous spiders through the plumbing to assassinate high-ranking targets.
