We bounce back to the charcoal set for today’s die.

Day 07 Box
We’ve got what’s sometimes called a d100, but what I think is more accurately called the percentile die.

Charcoal d100 or percentile
While a true d100 is more like a sphere that will roll right off your table if you aren’t careful (or roll it in a dice tray), the percentile die works together with your d10 to give you all the values you need from 1-100. Just in case you haven’t come across the before, basically the percentile die is your ten’s place (10, 20, 30…) and the d10 is your 1’s place (1, 2, 3, 4…) and you add them together. If if they both roll “0” (“00” on the percentile), then that’s a “100” value. Otherwise treat the 0 on either die as a 0. Example:
d100 = 20; d10 = 0 is 20
d100 = 0; d10 = 8 is 8
d100 = 30; d10 = 5 is 35
while
d100 = 0; d10 = 0 is 100.
So you get the benefit of a d100 without having to roll the Death Star.
