DnD Dice Roller

The Dungeons and Dragons dice function is a virtual dice that also let the user choose a type of dice to be rolled (e.g. 20 sided dice), provide a modifier, a number of rolls and whether the roll is for an Advantage, Disadvantage or None.

INSTRUCTIONS: Enter the following:

• (D) Dice Type to Roll (Number of Sides: 4, 6, 8, 10, 12, 20, 100-sided)
• (M) Modifier to the Roll
• (n) Number of rolls
• (AD) Advantage, Disadvantage, None

DnD Rolls: The virtual dice returns a list of rolls where there is a random dice roll from 1 to D and the user specified number added. Note: Advantage and Disadvantage rolls default to D20 dice and two (n=2) rolls.

The Math / Science

The Dungeons and Dragons utility generates a random number between 1 and D (e.g. 20).  It then adds the Modifier (M) to the random number and returns it.  It does this repeatedly for each roll (n).  

If there is an Advantage, there will be two (n=2) rolls of a D20 dice and the greater number of the two is added to the Adder.

If there is a Disadvantage, there will be two (n=2) rolls of a D20 dice and the lesser number of the two is added to the Adder.
