SirrDice

Your emotional support dice thrower.

SirrMizan rolls dice for any tabletop RPG, right inside Discord. Type a plain expression like 2d6+3, 4d6kh3 (keep the highest 3) or 6#1d20 (roll a set), with the !r prefix or the /roll slash command. Results stay clean and readable, the maths is shown, and the rolls use a cryptographic RNG. It works in English, French, German and Spanish. Simple and Basic to use.

What you can roll

• !r 1d20+5 a check with your modifier
• !r 2d20kh1+5 advantage: two d20, keep the highest, add 5
• !r 2d20kl1 disadvantage: keep the lowest
• !r 4d6kh3 one ability score, drop the lowest die
• !r 6#4d6kh3 all six ability scores in one message
• !r 1d100 percentile, for Call of Cthulhu and friends
• !r 3d6! exploding dice: a six is rolled again and added to it
• !r 2d6+1d4+3 mix any dice and modifiers
• !r 1d20+7 Goblin name a target so the table can follow

Advantage is just 2d20kh1: no special keyword to memorize, and the same keep/drop logic covers every house rule you can spell with dice.

Name the rolls you keep typing

!alias perception 1d20+7 once, then !r perception for as long as you play. Aliases are yours, not the server's, so they follow you from one table to the next, and they still compose: !r perception+2, !r 2#attaque.

Know the odds before you roll

!prob 4d6kh3 estimates a roll without making it: the average, the range, and a small chart of where the totals land. Add a comparison for your chance of landing there: >= 15 for that number or more, <= 5 for it or under, = 20 for exactly it. Nothing is rolled and nothing is saved.

Roll where only you can see it

/roll 1d20+7 hidden:True answers you and nobody else, leaving nothing in the channel. For the secret check, the hidden perception, the attack the table should not read yet.

Four languages, really

One /setlang per server and the whole table plays in English, French, German or Spanish: replies, help, errors.

Fair by design

Every roll uses a cryptographically secure random generator (secrets.SystemRandom), the kind that protects passwords. No result can be predicted, by anyone, including us.

Privacy without the asterisk

No messages, no roll history stored. /forgetme deletes what little there is, immediately.

Everything is free

Every command, every language. No premium tier, no vote-locked features.

Make it yours

/setprefix for your own prefix, /setcolor for your embed color, /setrollshort for one-line results, /defaultroll for the table's go-to roll, /settings to read them all back. Works in DMs too, and SirrDice can be added to your own account, to roll in any server even one it was never added to.
