About this project
What does Spider Moon add?

During the rare Spider Moon event, the weight of spider spawns will be greatly increased, and during a Super Spider Moon, all mob spawns will increase by a large amount as well, leading to a world overrun by creepy crawlies.
For added creepy-crawliness, try it with Nyf's Spiders
