Long story short, I'm working on an editable, self-updating Spreadsheet/Character Sheet. I want to incorporate features like Jack of All Trades or Remarkable Athlete that apply a portion of a character's proficiency bonus to various ability checks. Basically, there would be a check box labeled "Jack of All Trades" that, when checked, would apply half proficiency bonus rounded down to all non proficient ability checks on the character sheet (including initiative). Same idea for Remarkable Athlete (but round up and Str/Dex only).
Are there any other features like these that basically only add some or all of proficiency bonus to all instances of an ability check (so Dwarven Stonecunning wouldn't count) other than Proficiency, Expertise, Jack of All Trades or Remarkable Athlete?
