Expanded Beasts

Because there needs to be a little bit of fun in beasts.

Funeral Butterfly

Not every beast that hunts seeks to kill. A Funeral Butterfly is a beautiful sight to see, with what seems to be six pure white wings bordered in black hiding a tiny black body within them.

Graveyard Home. Funeral Butterflies make their home in graveyards, and are typically benign creatures. They feed off the emotional sadness of those who visit, fluttering around them but not attacking.

Death Robbers. Funeral Butterflies, when angered by someone disturbing their nest or someone trying to attack them, will attack using their own memories, having known the sadness and anger of many who visit the graveyards. Upon knocking someone unconscious, they draw from their victim every last memory of death. There are stories of people who purposely aggravated Funeral Butterflies to forget a death that they cannot bear to remember. This memory can be restored by a Greater Restoration spell.
