[RPG] What counts as the lowest value on a percentile die?

dice

If I'm making an image with a standard set of seven dice, all showing as having rolled the lowest possible result, I obviously want to have that be 1 for six of them, but what should I use for the percentile one? 00 or 10? Is there ever any circumstance in which it's rolled on its own?

Best Answer

It's system dependent.

Let's see, the "percentile die" is a combo of two dice: the one numbered 00 to 90 (d10×10) and the one numbered 0 to 9 (d10) and then summed up.

Now, it depends on the system how to read them, as there is no system-agnostic decision on the one case we are most interested in:

The system determines if "00, 0" is read as 100 or 0 (just like it decides if "0" is 10 or 0). Usually it does so either in form of text or by providing tables — if there is a 0 column/row or a 100 one.

The "00, 0" = 100 is the more widespread choice, as it generates 1–100. Among others, this is used for example in D&D and Hackmaster1 interpretation (unless one interprets "00, 0" as 10 and "90, 0" as 100).

The "00, 0" = 0 is the standard interpretation for games that use 0–99 tables. Among these is one edition of Pendragon.

Be easy on yourself

The otherwise lowest value ignoring the "00, 0" outlier is "00, 1", a 1.
