[QUOTE="DanmarLOK, post: 4413621, member: 71480"] In terms of scaling to party size, I'd simply remove one position on the track per missing player. For your example of 3 PC's then make it a 7 position track. That gives them a chance to succeed in one round if they all take a role as primary and they'll have 6 shots in two rounds. In terms of roles, I'd say you'd want a minimum of 2 primaries and the third could take the role of either support or observer. For four PC's you might to do it as 2-1-1 or another 3-1or1. I didn't put it in there but I'd planned that the non-primary roles are voluntary, if the party wants they can certainly have 5 primary particpants. The Observer and Support are in there to give leeway for the group to allow characters without any skills to ride the coattails of the others and not adversely affect the outcome and that's pretty well based on reality as well as 'reality' I think. I'll have to fix the typo's and errors tonight, I neglected to sync my memory stick last night so I don't have a current copy of the word doc. The length of the legs could certainly be extended or shortened and if you make them unequal lengths then you're also adjusting the difficulty of the challenge. A longer leg = harder to achieve the end result. After doing the rough math, right now as written a Moderate challenge (base 20 + level) is less than a 50% chance of success assuming level 1's with skill levels of 9. I know that it's possible to have a skill level of up to 15'ish at level 1, legally, 5 for Trained + 4 for stat + 3 for skill focus + 2 for personal racial + 1 for group racial. But typically only for one skill and in generaly I think a 9 is much more likely. An easy challenge (base 15) with a skill level of 9, should end up with a success of some level about 70%+ of the time? A hard challenge (base 25) with a skill level of 9, is only going to have some level of success maybe 25% of the time? So you have roughly a range of 70% - 45% - 25% on Easy, Medium, Hard that it will be somewhat successful but wait there's more that throws those numbers off! The chances to achieve total success are much fuzzier. Essentially the party has to get track length / 2 - 1 non-failures in a row assuming equal length legs. But to get total failure they also have to get the same number of failures in a row. The percentages of success go up, perhaps significantly if you use the Major success rule because then each successful roll is worth two failures. The use of the Sustain roll also offsets the percentages because it means that just because a roll isn't a success doesn't mean it's necessarily a failure. Also the Heroic Interrupt can be used to offset one failure per round so that also increases the chances of as successful ending. So in the end, the math on this is going to be pretty nasty I think to compute the chances. I'll leave that up to someone else. All I need is a rough rule of thumb which I think I have now, that a Moderate challenge is between the Sustain system and the Heroic Interrupt option is a better than 50% chance to succeed. And an Easy one is pretty likely to succeed, probably approaching 85% likely while the chances of total success are less likely. And vice versa. If you do actually need a binary result, total failure or total success, this isn't the best system. I would go with the original system, get X successes before 3 failures and use these base numbers (15/20/25) for your chances of success. The change they made in the errata to DC's made that system useless in the opposite direction but using a 15/20/25 it's reasonably okay to use for a binary result. [/QUOTE]
