Q 98: Some creatures list poison as having the save DC be Constitution-based, and others don't list what the save DC is based on. (e.g. the Greensting Scorpion, which does say it's Con-based, and the House Centipede, which says nothing about what the save DC is based on.) Is it valid to assume that the save DC is just fixed for those who say nothing of it, or is it more appropriate to assume that they're all Con-based unless they specify otherwise?
