[RPG] Do proficiency bonus increases due to levelling apply to skills gained from background

backgroundcharacter-advancementdnd-5eskills

I'm playing my first D&D 5e character, a Wood Elf Fighter with the Soldier background. I have proficiency in the skills Acrobatics and Survival from the Fighter class, and Athletics and Intimidation from the Soldier background

I've just reached level 5, so my proficiency bonus increases from +2 to +3.

It makes sense that this bonus increase applies to my Fighter skills, since my level as a Fighter has increased, but do I also increase the proficiency in the two background skills?

Best Answer

Yes.

Proficiency isn't tied to anything except your character level (i.e if you multiclass for example Rogue 3 / Cleric 2, your character level is 5, which means your proficiency bonus is +3).

Your proficiency bonus increases everything you're proficient in, full stop. This applies to attacks with weapons you're proficient with, saving throws you're proficient in, skills you're proficient in, etc.

From the Basic Rules, p. 7:

Proficiency Bonus

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)
