Rolz

When inside a room, any die roll you make will be shown to the other people there. You can also send chat messages if you put a special character in front of the line. You can use either a slash "/" or a pound sign "#" as the chat character (depending on your keyboard layout, one of them should be useful), like this:

/this is a chat message


In order to get a result, please enter the dice code into the input field and hit enter. You can also click on the standard dice on the right to load them into the field. Click double if you want to roll one of them right away. It's an AJAX application, magical things will happen!

Examples: (click once to load, click twice to roll right away)

Basic Dice Codes:

  • Take the highest: if you want to roll multiple times but have only the highest result count, use "H".
    Example: 2H20
  • Take the lowest: if you want to roll multiple times but have only the lowest result count, use "L".
    Example: 2L20
  • Drop the lowest: if you want to drop the lowest die result, use "I" instead of "D" in the dice code.
    Example: 4I6
  • Fudge Rolls: 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: 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): 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
    You can also roll without the wild die failure option by using the V code:
    Example: 4V6
  • Take X highest rolls: This rolls a number of dice and then adds the highest results together.
    For example, roll a d10 7 times and add the highest 4: 7D10z4
    The default die of this roll type is d10, so 7z4 can be used as a shorthand for 7d10z4.
  • Unique rolls: use "N" to make a series of rolls with only unique results.
    Example: 4N20

Success-Based Rolls

  • Count the number of successes: to see how many dice rolled equal to or greater than some number, use "E".
    Example: 4D6E4
    The default die of this roll type is d6, so 4e4 can be used as a shorthand for 4d6e4.
  • Successes with additive re-roll: to see how many dice rolled equal to or greater than some number, use "R" if you want the individual die maximum to trigger a re-roll. This way, you can have target difficulties greater than the max number of the die. The system also gives you the number of ones rolled (if there were any) so you can judge whether an action resulted in a fumble.
    Example: 4D6R8
    The default die of this roll type is d6, so 4r8 can be used as a shorthand for 4d6r8.
  • Successes minus failures: to see how many dice rolled equal to or greater than some number, and subtract the amount of ones rolled, use "F".
    Example: 4D6F4
    The default die of this roll type is d6, so 4f4 can be used as a shorthand for 4d6f4.
  • Successes "plus": to see how many dice rolled equal to or greater than some number, and roll every max result again and see if it's another success, use "M".
    Example: 4D10M4
    The default die of this roll type is d10, so 4m4 can be used as a shorthand for 4d10m4.
  • Successes with everything: to see how many dice rolled equal to or greater than some number, and roll every max result again, and subtract the amount of ones rolled, use "S". This is probably the one you want for most systems.
    Example: 4D10S4
    The default die of this roll type is d10, so 4s4 can be used as a shorthand for 4d10s4.
  • Successes with multiple dice: Some systems use the cumulative result of two or more dice to determine successes, here the sum of several dice is compared to the difficulty rating. To emulate this, you can group dice like this:
    Example: 1D6:6S4, meaning 2d6 will be rolled and 4(+) is a success.
    Example: 5D6:8S10, here a d8 and a d6 will be rolled, a sum of 10(+) is a success, the entire check is rolled 5 times.
  • Maximum possible die result counts as two successes: to see how many dice rolled equal to or greater than some number, use "X".
    Example: 4D6X4
    The default die of this roll type is d6, so 4x4 can be used as a shorthand for 4d6x4.
  • Get the highest roll: To see only the highest roll, just leave the success/difficulty rating out.
    Example: 4D6R

Power User Stuff:

  • To see how an individual result came to be, let the mouse pointer hover above the number to see more details. If your browser won't show the details, click on the result to expand it instead.
  • Multiple rolls at once: to roll for multiple things (e.g. an attack and a damage roll), you can chain together dice codes by semicolons.
    Example: 1D20;1D6+2
  • A number of rolls: if you want to repeat the same roll for a number of times, use the repeat command. If you also want the sum of the rolls, use sum instead of repeat.
    Examples: repeat 6 3D6 or: sum 6 3D6+3
  • You can add comments to your roll by appending a pound sign # followed by some text to your code, like this: 1D20+2 #attack roll
  • Custom attributes: another way to define custom rules for a single roll command is using attributes. The following attributes are currently supported:
    • reroll: ignore one or more results and roll again ( reroll=1,2 4d6 )
    • round: round up all results below this number ( round=3 d10 )
    • explode: specify one or more results that cause the die to be rolled again and the result added up ( explode=5,6 4d6 )
    • default die: specify another default die ( die=4 7z4 )
    • count: count the occurrences of specific die results ( count=1,2 10d6 )
    You can combine attributes with another, and also use macros (see below) to invoke them. It doesn't matter if an attribute comes before or after the actual dice code, as long as they are separated by a space.
  • Defining criticals: you can specify what your critical rules are with the rule crit command.
  • You can define macros to automate repetitive die rolls or often-used number constants (such as your attack bonus).
  • Saving and loading user data: you can save your customizations (such as the macros you defined) for later. To save your current session, type "save MyCoolUserName" where MyCoolUserName is an arbitrary name for your session. You have to remember this name in order to retrieve the session later with the corresponding command "load MyCoolUserName".
