Dice Rolls and Skill Checks

Call of Cthulhu uses dice to decide how high-tension situations are resolved, just like most other tabletop RPGs. However, passing a skill check in Call of Cthulhu is a bit different than in, say, DnD. You actually want low numbers, not high numbers.

Remember when I mentioned that the skill ratings are used for percentile rolls before? This is what I was talking about. It’s simple: when you need to make a skill check, roll a hundred-sided dice. If the number you roll is lower than your rating with the skill being used for your task, then you pass the check. For example, let’s say you want to see if there are any monsters hiding nearby. When you do a skill check, you use the rating of the appropriate skill, which in this case would be the Spot Hidden skill. In this example, your Spot Hidden skill rating is 40%. When you roll the D100, if the number you roll is equal to or less than your Spot Hidden skill rating of 40, you pass the check and your investigator notice that there is a monster sneaking up behind you. If you roll above 40, then your investigator doesn’t notice the monster.
