Interesting article on Roll 20 macro for indicating what AC is hit.
Simply in double square brackets indicate what is needed to hit AC0 and subtract the d20 roll.
From the example in the article of a 7th level fighter: [[14-d20]].
When I first tried this, I got that I hit AC 11, hovering over the result shows that a 3 was rolled.
I think I’ll make new macros for proficient weapon, non-proficient weapon, and specific magic weapons. Thus a button click should reduce the need to type formulas and slow things down.
