Common RPG Terms

Dice Notation
Like most classic RPG systems, Adventure Master uses a variety of polyhedral dice. The type of die is notated by the letter “d” followed by the number of sides the die should have. Here are the most common examples:
- d4: A four-sided die.
- d6: A six-sided die.
- d8: An eight-sided die.
- d10: A ten-sided die.
- d12: A twelve-sided die.
- d20: A twenty-sided die.
- d100: A percentile roll (see below).
Rolling Multiple Dice
The rules will often call for multiple dice of a certain type to be rolled, and their results added together. In this case, the multiple dice will be notated as a number preceding the die type. In example:
- 3d6: Three six-sided dice, added up.
- 2d8: Two eight-sided dice, added up.
- 5d4: Five four-sided dice, added up.
Dice Modifiers
Modifiers to dice rolls are used frequently. A modifier is a numerical bonus or penalty that is added or subtracted from a dice result. In example:
- 1d20+2: Roll one twenty-sided die and add +2 to the result.
- 2d6-2: Roll two six-sided dice, with -2 subtracted from the total
Percentile Dice (%) AKA d100
The rules may require a d100 or “percentile” roll. This can be accomplished by rolling two ten-sided dice, using one for the “tens place” and one for the “ones place”.
X-in-6 Rolls
Some rules indicate an “x-in-6” chance of something happening. This means roll 1d6; if the result is equal to or less than the chance, the thing happens.
Compatibility
Five decades of fantasy adventure gaming has produced a vast offering of content, much of which is quickly and easily compatible with this game. Adventure Master brings compatibility to the forefront of its design, offering a comprehensive set of procedures and advice for not just converting classic and third party adventure modules into the ruleset, but also transforming any premade adventure (no matter how linear) into a dynamic addition to your sandbox campaign.
