Proficiency Bonus - Class

Player's Handbook

The table that appears in your class description shows your proficiency bonus, which is +2 for a 1st-level character. Your proficiency bonus applies to many of the numbers you’ll be recording on your character sheet:

• Attack rolls using weapons you’re proficient with
• Attack rolls with spells you cast
• Ability checks using skills you’re proficient in
• Ability checks using tools you’re proficient with
• Saving throws you’re proficient in
• Saving throw DCs for spells you cast (explained in each spellcasting class)

Your class determines your weapon proficiencies, your saving throw proficiencies, and some of your skill and tool proficiencies. (Skills are described in chapter 7, "Using Ability Scores", and tools in chapter 5, "Equipment.") Your background gives you additional skill and tool proficiencies, and some races give you more proficiencies. Be sure to note all of these proficiencies, as well as your proficiency bonus, on your character sheet.

Your proficiency bonus can’t be added to a single die roll or other number more than once. Occasionally, your proficiency bonus might be modified (doubled or halved, for example) before you apply it. If a circumstance suggests that your proficiency bonus applies more than once to the same roll or that it should be multiplied more than once, you nevertheless add it only once, multiply it only once, and halve it only once.

Bob imagines Bruenor charging into battle with an axe, one horn on his helmet broken off. He makes Bruenor a fighter and notes the fighter’s proficiencies and 1st-level class features on his character sheet.

As a 1st-level fighter, Bruenor has 1 Hit Die—a d10—and starts with hit points equal to 10 + his Constitution modifier. Bob notes this, and will record the final number after he determines Bruenor’s Constitution score (see step 3). Bob also notes the proficiency bonus for a 1st-level character, which is +2.
