The ability score dice rolls—such as STR (Strength) and INT (Intelligence)—are essential when creating an investigator (PC) in Call of Cthulhu.
This simulator allows you to roll each ability score (STR, CON, SIZ, DEX, APP, INT, POW, EDU) one by one, complete with rolling animations and sound effects.
It supports both the 6th and 7th editions, and you can switch between rule sets with a single button.
All formulas that differ between editions—such as ability score generation, HP/MP/SAN calculations, and the damage bonus table—are accurately reflected, so you can use the simulator exactly as-is for your current session.
Once all ability scores have been rolled, the simulator automatically displays derived stats such as HP, MP, starting SAN, MOV, and damage bonus.
It also analyzes the tendencies of your rolls to suggest the top three suitable occupations, and even generates estimated height, build, and appearance impressions.
All results can be copied directly into your character sheet or notes.

Frequently Asked Questions
Q. Which edition should I use, 6th or 7th?
A. Use the edition of the rulebook used in your current session—whether you are a player or Keeper.
If you’re unsure, the 7th edition is widely used in recent sessions and is generally a safe choice.
Q. What happens if I switch editions midway?
A. Because the formulas differ between editions, switching will reset all previously rolled results.
It’s recommended to choose an edition before you begin rolling.
Q. Are the displayed height and appearance values official?
A. No. These impressions are not official rulebook values—they are simple flavor suggestions based on your ability scores.
Feel free to decide your investigator’s actual appearance however you like.
Q. Are the recommended occupations mandatory?
A. Not at all. They are simply suggestions based on statistical tendencies.
Choose any occupation that fits your scenario or the character you want to portray.
Q. Does this tool cost anything?
