Where this extension is useful, it is indispensible in streamlining gameplay so my players and I can focus on the game and not the rules. That's the best sort of extension.
This product does something that I did manually for in-person games. Now I don't have to remember various AC breakpoints to say what blocked an attack. Frees up mental bandwidth!
ThanX Peter!
...and if there are tweaks you make that you think EVERYONE would, let me know and I might incorporate them. Come to the Discord and ping me.
