Dice Modifiers
-
Modifiers are special notations that can change the value of dice rolls, their appearance, order, and more. You can generally combine multiple modifiers of different types.
The modifiers listed below are not comprehensive but are the most commonly used on Grog Space. More will be added as needed.
Simple Math
All basic mathematical notations are accepted.
Sample Rolls:
/roll 1d20+2
Addition
/roll 1d20-2
Subtraction
/roll 1d20x2
Multiplication
/roll 1d20/2
DivisionKeep (k{x} / kh{x} / kl{x})
The following is added to the Standard or Percentile die formula.
The Formula:
k = Abbv. for 'Keep'.
h = HIghest die.
l = Lowest die.
n = Number of dice to keep.The keep modifier allows you to roll a collection of dice but to disregard all except for the highest or lowest result(s).
This process allows for the Advantage/Disadvantage system as utilized in Dungeons & Dragons 5th Edition.
The notation of the keep modifier is a lowercase k, followed by the roll that should be dropped ("h" = "highest" or "l" = "lowest"), and the number of dice to drop; if omitted, the system will default to "highest".
Sample Rolls:
/roll 2d20kh1
Roll two d20, keep the highest one.
/roll 2d20k1
"h" omitted, but defaults to above.
/roll 10d10kh2
Roll ten d10, keep the highest two.When outputting the roll, the kept rolls aren't modified, but the dropped rolls are given the "d" notation in the results:
Results:
6d8k3: [3d, 6, 7, 2d, 5, 4d] = 9
Target Number ({cp})
Some systems utilize dice pools and count successes, whereby the total is equal to the number of rolled dice that reach a particular target number on the dice, rather than the combined value of the dice rolls.
Target numbers may also be added to regular non-pools as well, like a single d20.
This can be achieved by adding a Compare Point notation directly after the Standard or Percentile die notation.
Sample Rolls:
/roll 5d10>=9
Roll 5d10 with a target number of 9 or higher.
/roll 10d10>=7
Roll 10d10 with a target number of 7 or higher.Other Compare Point Notations:
/roll 2d6=6
Only a roll of 6 succeeds.
/roll 4d3>1
Roll greater than 1 succeeds.
/roll 4d3<2
Roll lesser than 2 succeeds.
/roll 5d8>=5
Roll greater than or equal to 5 succeeds.
/roll 6d10<=4
Roll less than or equal to 4 succeeds.
/roll 1d20>15
Roll greater than 15 succeeds on a d20.Group Rolls
You can perform rolls in a group using comma-separated notations. The results will be summed together and modifiers can be run on entire group notation.
A roll group is differentiated from normal roll expressions by surrounding the expression in curly braces; {4d10+5d6} or {2d6, 5*d20}. Remember, basic mathematics can be added to any notation, even in a group.
Sample Rolls:
/roll {4d6, 2d10, d4}
Each sub group is rolled, then tallied.
/roll {3d8*2, 20/2d10}
Math in each sub-group, then tallied.Group Modifiers
Group Rolls can be used with most standard modifiers, by appending the formula after the closing curly brace.
Sample Roll
/roll {4d10+1, 5d6}k2
Tally groups keeping the highest two.Advanced Notations
