[QUOTE="FireLance, post: 5727351, member: 3424"] Mind you, there are other ways to play with d20+mod vs DC instead of simply increasing the modifier and the DC. What 4E has called "brutal" dice (with respect to rolling for weapon damage), i.e. allowing for a re-roll if the result is below a specified number, is another possible way to tinker with the probabilities. Let's say that skill allows you to re-roll results that are below your "skill level"; if you have a skill level of 5, say, than a roll of 1-4 on a d20 is always disregarded. Effectively, you will always get a result of between 5 and 20, and are rolling 1d16+4. Assuming no other modifiers (and a DC cap of 20), this means that success is never impossible even for an unskilled character, but highly skilled characters will succeed more often, possibly even automatically. An unskilled character would succeed on a DC 10 check about 55% of the time. A skill 5 character, would succeed about 75% of the time (12/16) and success would be automatic for a skill 10 character. EDIT: Past a certain point, it becomes more efficient to simply change the die type instead of re-rolling the d20. At skill 9, you might as well be rolling 1d12+8, for example. [/QUOTE]
