# 1d10 x 1d10

If we are "off-target" when we cast teleport, we end up a distance from our intended target equal to 1d10 x 1d10 percent of the distance we intended to teleport. Interesting, why don't we just roll d%? Is there a difference between 1d10 x 1d10 and d%?

Does rolling 1d10 x 1d10 generate numbers between 1 and 100, excluding prime numbers larger than 10?

With 1d10 x 1d10, you can't generate a multiple of any prime number larger than 10, e..g. 22 = 11 x 2 so there's no way to get that by multiplying two numbers in 1-10 range. In addition, you have an uneven distribution of result, e.g. there's 1% chance of getting 100 (10x10), but a 3% chance of getting 4 (1x4,4x1,2x2).

As you can see by @Cadence's set, there are only 20 results (out of 100) that are 50+ (And therefore 80 that are under 50). Heck, there are 35 of 100 that are 15 or under! The median is 24.

I wonder if the developers knew what they were doing when they chose this multiplication method of generating a percentage. The distribution is highly skewed away from being "on target".

D100 has a much higher chance of being skewed away from on target.

Not that highly. It's skewed well towards you winding up less than 50% of the total distance away from the target.

Oops, I was confusing this with the chance of mishaps table. So, it's a beneficial distribution. Weird, but beneficial.
