It will bring you to a server selector, where you can install it on any server you have the correct permissions for.
In any channel that the bot has permission to view and send messages, input /r followed by the roll you want to perform.
Rolling Dice
/r XdY - Roll a number of Y-sided dice equal to X. If omitted, X becomes 1 and Y becomes 0
Examples
/r 1d20 # Roll one 20-sided die
/r 3d8 # Roll three 8-sided dice
/r d10 # Roll one 10-sided die
Math
X [+, -, *, /, ^] Y - Do math! Currently supports addition, subtraction, multiplication, division, and exponentials. All of this can also be done with dice! If omitted, both X and Y become 0
Examples
/r 2 + 2 # Add 2 and 2
/r 500/4 # Divide 500 by 4
/r 2d10 * 5 # Roll 2d10 and multiply the result by 5
Parentheses
(X+Y)*Z - Order of operations is followed, meaning things in parentheses are resolved first, even when nested
Examples
/r (1d20+3)*2 # Roll a d20, add 3, and multiply the result by 2
/r (2d4)d6 # Roll 2d4, and roll a number of d6 equal to the result
/r (15/(2d6-3))^2 # Roll 2d6, subtract 3 from it, divide 15 by that result, and square the whole thing
Keep and Drop
XdY[k, kh, kl, dh, dl]Z - Keep or drop Z values from the highest or lowest ends of a roll. When using k alone, it defaults to highest.
Examples
/r 4d6k3 # Roll 4d6 and keep the highest 3 results
/r 2d20dh1 # Roll 2d20 and drop the highest result
/r 6d4dl3kl1 # Roll 6d4, drop the lowest three, and keep the lowest result that remains
