Intelligence measures mental acuity, accuracy of recall, and the ability to reason.
#### Intelligence Checks
An Intelligence check comes into play when you need to draw on logic, education, memory, or deductive reasoning. The [[Arcana]], [[History]], [[Investigation]], [[Nature]], and [[Religion]] skills reflect aptitude in certain kinds of Intelligence checks.
