I am playing a shortsword-wielding monk/rogue. I know unarmed strikes do not qualify for Sneak Attack.
My question is: At later levels, can I sub in my monk damage die from Martial Arts (which will eventually be better than the 1d6 on a shortsword) and still be considered to be using the shortsword, and thus take advantage of its Finesse property to also use Sneak Attack?
I do understand that this changes the weapon die and NOT the sneak attack die.
From a roleplaying perspective, I imagine it as being that rather than simply having unarmed strikes that are more effective, I actually enhance my use of the shortsword with my martial arts because it is a monk weapon, and thus improve its intrinsic damage to match my base damage as a skilled monk.
