When you apply unarmed strike as "carried" or "equipped" on the inventory tab, if you also have two weapon fighting it does not show those attack bonuses for unarmed two weapon fighting
I want to point out the magnitude of what you are asking. In the current files we have two distinct blocks - the first is the Unarmed Strike you are talking about and then the following is what is applied to the other weapons. Mind, this is the latest code I have on these two files.
Now, let's pull up the base file where those values come from:
If you feel up to the task of adding the required fields, I'll be happy to include it. But as you can see, the magnitude is impressive.
By my meager estimates, this is probably a 60-120 minutes block of time adding in the correct fields, altering how Unarmed works, and then deriving correct values. And of course the required testing.
If I knew how to do the coding I would certainly undertake it. I am cursed that I only took a couple of programming courses and they were lightspeed pascal :/
