The new theme will bring not only new monsters and items and spells, but also some elements of gameplay, like resistances and vulnerabilities. Sticking on the way of making monsters as different as possible each other I've the chance to give some of these new features to the undead guys.
So, less words more code, this post is only to make you know that, since I'm proud to have released v0.1, I've not finished at all with you :)
