phrasing of homebrew race trait for proficiency
I'm creating a homebrew race and I'm having difficulty getting the skill proficiency working correctly on a race trait
The trait phrasing "You are proficient in the Deception skill." works fine and when the character selects the race the correct proficiency is granted in the character sheet.
But, "You are proficient in the Insight and Deception skills." does not work and ends up placing a skill "Insight and Deception" on the character sheet.
How should I phrase it for both skills to be granted proficiency?
