I need help with snippet code in homebrew I found a thread by Stormknight that explains a lot of it and it really helped but I can't figure out how to use snippet code with skills like for example intimidation and persuasion I know how to do modifiers for str and dex but not skills I have a roll currently that I am trying to calculate automatically that is intimidation modifier + Constitution modifier and I just can't find any information anywhere on skill specific snippet code

There aren’t any skill specific snippets is why. You would have to do something like this:

{{modifier:con+modifier:cha+proficiency}} if you are proficient in Intimidation, or {{modifier:con+modifier:cha}} if you are not proficient.

Ok thank you I was wondering if I would have to but I wanted to be sure so that proficiency or expertise in a skill could be automatically added no big deal tho
