Call of Cthulhu dice bot for Discord
SirrMizan is a d100 roller you keep right inside Discord, made for percentile games like Call of Cthulhu. Roll 1d100, check it against your skill, and get on with the investigation.
Roll 1d100 and read it under your skill
Call of Cthulhu lives on the percentile die. You roll 1d100 and you want it equal to or under your skill rating. The bot rolls the number for you with a cryptographic RNG, so the result is genuinely random, and then you read it against your sheet. If your Spot Hidden is 55 and the d100 comes up 42, you noticed something. If it shows 78, you walked right past it. Use !r 1d100 or /roll 1d100, whichever feels faster mid-session.
Damage and other dice
Weapons and spells lean on the small dice. A knife is 1d6, a heavy revolver might be 1d10, and you can add a flat modifier when you need one, like 1d6+1d4 for a thrown attack with a damage bonus. Mix dice and numbers freely in one expression. Drop a name at the end and it shows up on the result, so 1d10 Cultist keeps the table clear about who just took the hit.
Bonus dice, penalty dice, and Sanity stay in your hands
The bot does not have a special Call of Cthulhu mode. There is no bonus die or penalty die keyword, and it will not look up Sanity loss for you. That is fine, because the underlying roll is simple: you throw 1d100 and judge it. For a bonus or penalty die situation, roll the percentile a couple of times with a roll set and pick the tens result your rules call for, then read it against your skill. The dice are honest; the interpretation is yours and your Keeper's.
- A straight percentile roll. Compare it to your skill: equal or under succeeds.
- Same d100, labelled so the table knows which check it was.
- Knife or light weapon damage.
- Heavier weapon damage, with the source named on the result.
- Weapon dice plus a damage bonus die in one roll.
- Rolls 1d100 twice, handy when a bonus or penalty die means rolling the tens again.
Add SirrMizan from the site or with /roll, point your investigators at it, and let your emotional support dice thrower handle the percentile.
