How Does Expertise Work?

Expertise can only apply to skills that you’re already proficient in. It doubles the proficiency bonus that you get in that skill.

So, for example, let’s say you’re level 5, have a +3 Intelligence modifier, and are proficient in Arcana. At level 5, your proficiency bonus is +3, so you add +6 to your Arcana checks.

Now, let’s say you have Expertise in Arcana. Instead of adding a +3 proficiency bonus, you add +6. You still add the normal +3 Intelligence modifier to the skill at well, totaling a +9 on Arcana checks.

Here’s a table with what your proficiency bonus is at each level, along with your proficiency bonus if you have Expertise in a skill:

You cannot apply multiple instances of Expertise to the same skill.
