I have a rider effect on all critical hits in my 5e house rules. The problem is, I always forgot to actually apply this rider. So, I figure, I should use some API techno-wizardry to edit critical hits so that all of them will include a little note reminding me of the rider effect. This, I thought, would probably be pretty easy to figure out on my own even without any prior experience with the API or editing character sheets or anything, but after crawling through a few Google searches the closest thing I was able to find is changing the crit damage on individual weapon attacks, which doesn't even seem to be an option for NPCs. Is there any way to force a note to appear whenever a crit is rolled using the Roll20 5e NPC sheets?
