Yeah, but I'm never going to apply more than a +/-4 on a roll. Anything more doesn't need to be rolled. So only the most difficult task would be impossible for a 1st level character with a +3 ability modifier. [Edit: Bad math. The -4 task would be impossible for the PC with no ability modifier, but the +3 AB guy would have a 27.75% chance at it.] That seems fine as a starting point -- these are 1st level B/X "zeroes" we're talking about.Dimirag wrote:Using two dice you have better chance of higher results but are limited to the 1-20 scale and won't surpass the top 20 result. With a bonus you get higher lesser and higher values.
Like I said, I really like the curve. I like the fact that the "gap" between proficient and non-proficient grows with level. For example, assuming no ability modifier, the non-proficient character has a 20% chance at an average task at 1st level, while the proficient character has a 36% chance. Fine. At 10th level, the non-proficient character has a 45% chance and the proficient character has a 69.75% chance. That's cool.
Maybe I'm just trying to warm myself up to it enough to overcome my aesthetic concerns.
