I have createdI'm playing my first D&D5eD&D 5e character and have just achieved level 5, 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
Race: Wood Elf
Class: Fighter
Background: Soldier
Skills: Acrobatics and Survival from the fighter class, and Athletics and Intimidation from my background.
When my character reaches 5thI've just reached level 5, so my proficiency bonus increases from +2 to +3.
DoIt 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 skills gained from my background skills?
