One Roll Engine is a Foundry VTT module, based on the One-Roll Engine (O.R.E) generic TTRPG system. This basic system is used for games such as Wild Talents, Monsters and Other Childish Things, and The Velvet Book.
Use the /ore command to roll a number of dice (d10s, ten-sided dice with the numbers from 1 to 10). You can type any
of the following, to roll 7 dice:
/ore 7d10
/ore 7d
/ore 7
/ore 7 #electric dash attack!
They will all result in the same thing - a chat message that includes the result of the roll, with dice grouped up to sets.
Any text written after the #, "flavor text", will also be included.
The dice shown on the left are the "sets" you rolled. Sets include two or more dice with the same value. A set's "height" is that value, while a set's "width" is the amount of dice. For example, rolling a pair of tens is a "2x10", which has width 2 and height 10.
Visually, the dice in the sets will be shown in a column of identical-value dice.
Sets can be clicked to select/outline them (visible only to you).
The dice shown on the right - which are smaller and uncolored - are the "loose dice".
Loose dice can be clicked to select/outline them (visible only to you).
Loose dice can be alt-clicked to make them go down, by 1 each time, until it goes below 1 and returns to its original value.
Expert/hard dice can be added using the syntax /ore 5d 1e6.
The 'e' can be replaced with 'E', 'h', or 'H'. If you don't put in the first number (e.g. /ore 5d e1) then the number of dice will default to 1. If you don't put in the second number (e.g. /ore 5d 1e), then the dice will default to 10.
The expert/hard dice will be added to the normal roll, becoming part of sets or loose dice as normal.
