I haven't been able to lock down a good command for adding inspiration dice with Avrae. Any thoughts/successes? 

 Best I have is a snippet 
!snippet Bin -a "1d6[Bardic Inspiration]" 
then when you attack add it after the attack

!a shortsword bin

To Hit: 1d20 (7) + 8 + 1d6 (2) [Bardic Insperation] = 17

Otherwise I have nothing. I cant workout how to add it to a roll after.

You can add the following snippet:

!snippet inspired -b "1d6 [Bardic Inspiration]"

 An example of using it:

!attack shortsword inspired
