Constitution 13 or 14: Will withstand adversityIt looks somewhat like the ancestor of the system shock roll. This seems to be born out by the sketchy description of Constitution on the previous page:
Constitution of 9 - 12: 60% to 90% chance of surviving
Constitution 8 or 7: 40% to 50% chance of survival
Constitution is a combination of health and endurance. It will influence such things as the number of hits which can be taken and how well the character can withstand being paralyzed, turned to stone, etc.The problem, of course, is that these two excerpts are all that is said about "withstanding adversity". There are no explanations on how to decide which number in the 60 to 90% or 40 to 50% ranges to use, although it's easy to assume that every point of Constitution equals +10% chance of survival. But there has to be an element of house-ruling, here, because the rules don't say when to use the rule, whether to check only once, or what else counts as adversity.
You could use this as the basis of a "death's door" house rule, for example: if a dying character is aided within 1 turn, a successful "withstand adversity" roll returns the character to 1 hp and a weakened state. Or you could use this for overwhelming damage, like falling off a 100-foot cliff: in addition to rolling for damage, the victim must also survive a "withstand adversity" roll or be killed.
It would be easy to add either a Target 20 or other resolution roll as a Withstand Adversity roll. For Target 20, add double Con - 5 to the roll, but don't add character class levels, as for other saves. For a different approach that doesn't require a formula, roll 2d6: if the roll is greater than or equal to Con, the victim is killed (or suffers some other devastating effect.) I'm leaning towards the latter for possible inclusion in the clone, because it's simpler, but it breaks a pattern in how rolls are made by making one "save" 2d6-based instead of d20-based.
Anyone else have thoughts on this subject?
