What do you think about an oportunity for gaining some superpowers in game ?
Im thinking in general something of plot related or complatly optional.
For exampe a mad scientist kidnap you and is making some horrible experiments and you become undead, half-demon etc ...
Or mayby in visiting a old mantion a Vampire bites you and you become vampire yourself ...
Or maybe even you make some secret ritual and became a Lich ? ...
What do you think ?
