You can add labels to dice notations as helpful identifiers. Simply add a `#`

symbol to the end of any notation. Also, it is very important to surround the symbol with whitespace on each side.

**Sample Rolls:**

`/roll 2d20k1 # Sword strike with advantage`

`/roll 6d6 # Fireball spell damage`

`/roll 1d% # Attempt at a sneak attack`

]]>The modifiers listed below are not comprehensive but are the most commonly used on Grog Space. More will be added as needed.

All basic mathematical notations are accepted.

**Sample Rolls:**

`/roll 1d20+2`

Addition

`/roll 1d20-2`

Subtraction

`/roll 1d20x2`

Multiplication

`/roll 1d20/2`

Division

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`

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.

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 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.

]]>**The Formula:**

**x** = Number of dice to roll.

**d** = Abbv. for 'dice'.

**n** = Die type.

A standard die has a positive number of sides, like a typical 6-sided die (d6), or a common 20-sided die (d20).

**Sample Rolls:**

`/roll d6`

Rolls a single 6-sided die.

`/roll 1d6`

Rolls one 6-sided die (as above).

`/roll 4d10`

Rolls a 10-sided die 4 times.

However, in a digital online environment, you can roll dice with nearly any number of sides. For example, a 3-sided die (d3) or even a 66-sided die (d66).

**The Formula:**

**x** = Number of dice to roll.

**d** = Abbv. for 'dice'.

**%** = Same as d100.

Percentile dice rolls a number between 1-100, and are specified with the format d%. This is shorthand for a 100-sided die (d100).

**Sample Rolls:**

`/roll d100`

Rolls a single 100-sided die.

`/roll d%`

Rolls a single 100-sided die.

`/roll 1d100`

Rolls one 100-sided die (as above).

`/roll 1d%`

Rolls a single 100-sided die (as above).

* Fate/Fudge* die types are also available. Formulas will appear here when those campaigns become available on Grog Space.
