[QUOTE="WheresMyD20, post: 6959490, member: 60772"] The closest approximation I can come up with using only 2d6 is to have one die be a normal 1d6 and the other die act as a control die. If the control die comes up 1 or 2, then read the normal 1d6 die as is (i.e. the roll result is a number from 1 to 6). If the control die comes up 3 or 4, then add 7 to the result of the normal die, producing a result between 8 and 13. If the control die comes up 5 or 6, then add 14 to the normal 1d6 die, producing a result from 15 to 20. Using this method, you can produce a linear range of all the numbers from 1 to 20 except for 7 and 14. If you want to get fancy, you can use some stickers on the control die to re-label it with two 0 sides, two 7 sides, and two 14 sides. This method provides an approximation within -3.3% to +3.3% percentiles. A target number of 15 or better is 3.3%-tiles easier to roll (33.3% vs. 30%) and a target number of 7 or better is 3.3%-tiles harder to roll (66.6% vs. 70%). A target number of 11 is exactly the same (50% using either method). The average discrepancy is 1.5%-tiles. [/QUOTE]
