Homebrew Horde of Rats Species Details

Horde of Rats is as it seems. A Horde of Rats. Rather than being an individual entity, the horde is a amalgam of rats controlled by a single hive mind, known as The Grand Rattus. Origins for these failed nightmares is wholly unknown as not even the hivemind, cursed with knowledge as it is, can find the point of its origin. However, it is believed they come from the underdark, sent by whatever horrible powers created them to wreak havoc upon the surface realm. The Rats idle in a vaguely human shaped pile, or can shift into other shapes. Each Rat can take up a different class if they so choose. Each Rat of the horde makes up 1 hit point of the pile, save for the Grand Rattus host, which makes up the last 10 hit points of the pile. This rat typically is three to four times the size of its companions, and is much cleaner and healthier looking. If any of the rats are purposefully moved beyond  three feet away from the Host, they are no longer under its control. The only counter to this is if the rat is forcefully separated and tries moving back to the host.
