Perform a number of rolls following common ttrpg rules. The rolls should be given to the program as a string, which is formatted as

    AdX [...] BdY [...] CdZ [...]

where this roll would be of A X-sided dice, B Y-sided dice, and C Z-sided dice. If you only want to roll one dice, you can ignore the first number (A, B, and C in the example).

In addition to the dice roll itself, the string accepts a number of different arguments, such that one roll can be:

AdX [rR] [tT] [lL] [hH] [A] [D] [E]

• AdX : Roll a number of A X-sided dice.
• +B : Add B to the roll.
• -P : Subtract P from the roll.
• rR tT : Re-roll all rolls that result in a number equal or lower than T. The maximum number of rerolls allowed is R. You can set R to 0 to allow for infinite re-rolls.
• lL : Drop the L lowest dice in the roll.
• hH : Drop the H highest dice in the roll.
• The following optional arguments are mutually exclusive, and are only available if the roll is a d20/1d20:
  • A : Roll with advantage (2d20 l1).
  • D : Roll with disadvantage (2d20 h1).
  • E : Roll with advantage + the Elven Accuracy feat (3d10 l3).
