A proficiency bonus is **a bonus you get to a roll.**
**It scales with your character as they level up**, and applies to **saving throws, skills checks, spell and weapon attacks, tools, and the ability to use certain armor or weapons effectively**. It also applies to **spell save DCs**
Your proficiency bonus is always based on your total character level, as shown in the **Character Advancement** table, not your level in a particular [[Resources/Rules/Basics/Class]]. For example, if you are a [[Fighter]]] 3/[[Rogue]]] 2, you have the proficiency bonus of a 5th- level character, which is +3.
