Giant spiders were quite simply enormous versions of regular spiders. Existing in various types, there was no way to singularly describe their appearance; with various types ranging in size from that of a dog to a house. Giant versions of tarantulas existed, as did black widows, spitters, spinners, and all manner of others. Their appearances, habits and environments all varied greatly. Goblins were known to employ them as mounts.
Giant spiders could attack in a variety of ways, typically whatever way their normal counterparts could. Some spun huge webs that prey easily stumbled into, while others spat a deadly poison. Some were capable of walking on ceilings, while others were not. Despite the differences between the types of giant spider, allweare formidable opponents and certainly not foes for any arachnophobes to face.
