[QUOTE="Nagol, post: 5468690, member: 23935"] From a math perspective, I think the SC system is dangerous to design/run for people without experience since the probability of success suffers such a quick drop-off as the minimum success number rises. People don't grok probability easily and most won't run the math to see what the expected success rate will be. I haven't kept up on the errata to the skill challenge system, but I believe the 6:3 set is expected to be a "hard" challenge. Depending on the table, aiming for the typical skill check to be around 9+ leads to less than a 1 in 3chance of eventual success and is probably a decent rate for a "hard" challenge with liberal opportunity to get bonuses from secondary sources. If every check gets +2 the chance of success rises to just over 50%; a +4 on every check moves it up to 80%. A consequence of this design is every point matters. Never select a secondary ability unless you expect a bonus to the roll sufficient to raise it above your best ability. If you don't have the highest effective ability, try to find some way to give a bonus to someone who does rather than taking a shot yourself. The system penalises lower than maximal abilities harshly. [/QUOTE]
