@JeremyECrawford sorry to bother you, but I have a question. Does a swashbuckler add her charisma mod to initiative as well as dexterity?

Initiative is a Dexterity check. Rakish Audacity lets you add your Cha. mod. to that check; it doesn't replace the Dex. check. #DnD https://t.co/btvfwvUNJX

What about if you multiclass as a Gloomstalker Ranger. Is it now you ‘dex mod. + cha mod. + wis mod. = initiative’?
You should ask this on Twitter, he doesnt see this comment.
