Core Mechanics
Basic Dice Rolls
Against the Darkmaster uses only a couple of ten-sided dice (or d10) for any roll involved during the game.
d100 Rolls
The vast majority of dice rolls will be percentile — or 1d100 rolls. This means rolling two ten-sided dice, possibly of different colors, and counting one of them as the tens and the other as ones (of course deciding before rolling which die will be the tens, and which the units).
So, a roll showing up a "5" on the tens die and a "7" on the units die will read as a "57"; a "3" and a "9" as a "39"; and a "0" and a "4" as a "04" — or simply "4".
The exception to this is a double zeroes, which does not read as a "0" but instead as a "100".
This way, the two dice combined produce any result within the 1 and 100 range.
d10 Rolls
Another type of dice roll in VsD will be simply d10 rolls. When you read "roll #d10", it means rolling # number of ten-sided dice and adding the results together.
d5 Rolls
In some occasions, you might be prompted to roll a d5, which would be a 5-sided die. To do so, simply use a d10, reading results of 1–2 as a one; 3–4 as a two; 5–6 as a three; 7–8 as a four; and 9–10 as a five.
