Every once in a while i remember reading about an underground (underdark?) creature that had somewhat following qualities:
- giant that lives underground
- it was very ugly and was extremely hunched to fit in the caves
- it had the ability straighten itself up, that granted it great bonuses, if the surroundings allowed it such a thing. I recall there being a bonuses to con and str, possibly size/reach increases.
- i read the creature entry from a book, so it wasnt a situation on the table that DM made up.
Id like to know the book it is from, edition it is from, it's name and the special quality details of this creature.
