Homebrew Monster - Arachne

[Rallaster]

Here's a monster I designed a bit ago, basically a young woman that hides a monstrous spider under her back.

Arachne CR 5

That is absolutely amazing, and a great trap for foolish players. If they see a woman being eaten by a spider, they normally try to save them, and then be surprised when the woman and the spider turn out to be one.
