Syntax

The basics

• !r 1d20
  Rolls a single 20-sided die. Exactly the same as /roll 1d20.
• d20
  The 1 is optional: d20 is one 20-sided die.
• 2d6
  Rolls a few dice at once. 2d6 is two six-sided dice.
• 1d20+5
  Adds or subtracts a flat number.
• 2d6+1d4
  Mixes different dice and modifiers in the same roll.
• 1D20 + 5
  Spaces and capitals are fine: this is the same roll as 1d20+5.

Keep and drop

• 4d6kh3
  Keeps the 3 highest dice (kh). The usual way to roll up stats.
• 4d6dl1
  Drops the lowest die (dl).
• 5d6dh1
  Drops the highest die (dh).

Advantage and disadvantage

Two ways to write it: keep the better of two dice yourself, or add the word after a roll of one die.

• 2d20kh
  Advantage: rolls two d20 and keeps the higher one. With no number after kh, it keeps one die.
• 2d20kl
  Disadvantage: keeps the lower of the two (kl).
• 1d20+5 adv
  Advantage in a word: adv (or advantage) after a roll of one die rolls it twice and keeps the higher, here 2d20kh+5. dis (or disadvantage) keeps the lower.
• adv 1d20+5
  The word works in front of the roll too.
• 1d20+5 advantage
  Each language's word works: advantage, avantage, Vorteil, ventaja, and for the lower die disadvantage, désavantage, Nachteil, desventaja.
• 4d6 adv
  Only on a roll of one die: on several dice it has no single meaning, so the bot refuses and shows how to say which dice to keep, like 4d6kh3.

Exploding dice

• 3d6!
  Exploding dice: any die landing on its maximum is rolled again and added to itself.
• 4d6!kh3
  Explodes and keeps the best three. The exploded die counts as one die, worth its total.

Repeating a roll

• 6#4d6kh3
  Rolls the whole expression several times. The 6# here gives you six stat lines.
• 3#1d20+5 adv
  N# goes with everything else: three attacks with advantage.

Names, default roll and aliases

The last five need your server's default roll or your own aliases, which the demo above doesn't have.

• 1d20 Goblin
  Add a name after the roll and it shows up on the result.
• !r
  On its own it falls back to the server's default roll, if one was set.
• !r +5
  A bare modifier is added to the default roll: with 1d20 as the default, this rolls 1d20+5.
• !r Goblin
  A name alone rolls the default roll under that name.
• !r adv
  adv alone rolls the default roll with advantage, when it is a single die.
• !r perception
  Rolls one of your aliases, saved with /alias.
• !r perception+2
  An alias is part of the roll: a bonus, 2# in front or adv after it all work.

Chances

• !prob 1d20+5 >= 15
  Your chances of reaching 15 or more, without rolling anything. <=, >, <, =, ≥ and ≤ work too, and so does adv.

Odds of a roll

Coming from another bot

Typed the way another bot or table writes it? The bot answers with the spelling that works here. Click one to see its answer in the demo.

• 4d6k3→ 4d6kh3
  k without h, as in Roll20, Foundry and Dice Maiden.
• 4d6d1→ 4d6dl1
  d and a number to drop the lowest dice.
• d%→ 1d100
  Percentile dice.
• d6!!→ d6!
  Roll20's compounding !!: a single ! here already adds the new roll to the die.
• 3d6x2→ 2#3d6
  x2 to roll the same thing twice.
• 4d6 k3→ 4d6kh3
  A suffix typed after a space.
• 1d20 >= 15→ !prob 1d20>=15
  A number to reach: that's a question for !prob.
• 2d10*2
  Multiplying or dividing: only + and - work in a roll, so nothing is rolled.
