Talk:Epic Precision

You deal halved sneak attack damage against creatures that are normally immune to sneak attacks.

Its divide the damage by half and not the number of dice. Also note that half of a 1d6 is not the same as a 1d3 and any rounding down only applies to the final result half point.

The possiblilties for half 1d6 is 0, 1, 1, 2 ,2 or 3 so the average is 1.5 and not half  the average of a 1d6 which is 3.5/2 or 1.75. But half of 2d6 also does not average to 3 (1.5 x 2) and is actualy 3.25. This is because for a single d6 on a roll of 1, 3 or a 5 when halved the result is rounded down but for multiple half points, the two halves become a whole. So for 50% of the outcomes a half point is lost or .25 on average.

A quick formula is (#d6)/2-.25 and round to nearest
