Basic Dice Codes
Keep the highest (or lowest): H/L/O

If you want to roll multiple times but have only the highest result(s) count, use the modifier "H". If you want only the lowest result(s) counted, use "L".

  • Drop lowest / keep highest 5 of 6D10: #6D10H
  • Highest 4 of 6D10: #6D10H4
  • Lowest 4 of 6D10: #6D10L4
  • Middle 4 of 6D10: #6D10O (<- that's an O not a zero)
  • 1o3d10 System (Rápido y Fácil): #3O

The default die of this roll type is d10, so 4H2 can be used as a shorthand for 4d10h2.

Fudge Rolls: U

If you want dice to have values from -X to +X, use "U" instead of "D" in the dice code, followed by X. Example: #4U1

Hero System damage rolls: B/K

The total result is counted as stun damage. On top of that, body damage is calculated by counting ones as zero, 2-5 as 1, and sixes as 2 points of body damage. You can also use the "" operator for the stun multiplier.

  • Example: #4B6
  • with stun multiplier: #4B6*3
  • For "killing"-type damage, use the K operator like this: #4K6*3
Wild Die (D6 System): W/V

The D6 System has a special rule for one of the dice in each roll, it becomes the "Wild Die". The Wild Die is rolled again as long as it comes up with the max result, but if the first roll is a 1 the next roll as well as the highest result of the other dice becomes a penalty. Two ones make a critical failure.

  • Example: #4W6
  • without the wild die failure option: #4V6
Stress Die (Ars Magica): A

Roll the Ars Magica Stress Die (reroll ones and double the result, 10s count as zero on initial roll, it's complicated). The number following the A is the number of botch dice (can be 0).

Anima Open Die Roll: Y

Roll a die, if the result is higher than a certain threshold: roll again, add the result, increase the threshold by one, roll again. If the first roll is lower than the failure threshold, the result is a fumble with a certain failure level, for more information refer to:

By default, the die is a D100, the up-roll threshold is 90, the fumble threshold is 3, and the fumble level modifier is 15.

  • Example: #Y
  • Different thresholds: #Y85:5
  • Different die and thresholds, no fumble level modifier: #D10Y8:1:0
  • with Natura 15+ (digit doubles cause open roll) #Y ex=digits
No Duplicates / Unique Rolls: N

Roll a number of dice, giving unique results (every result comes up only once).
