TL;DR Made a macro for rolling against a selected tokens AC in Pf2E that takes into account the attack mod, AC and AC modifiers and adapts the critical threshold of the roll on the fly and rolls it all in an easy to read template. Enjoy  :)  Result:  The popup from mousing over the 38: Just spent a good long time working this out and it seems a shame to keep it to myself as there's a lot there. /w gm &{template:default} {{name=Attacking @{target|character_name}}} {{Atk Mod [[?{Attack Mod|0}]]=AC Mod [[?{AC Mod|0}]]}} {{[[(d20cs>[[{@{target|ac}+?{AC Mod|0}+10-?{Attack Mod|0}, 20}kl1]])+?{Attack Mod|0}]] vs AC[[@{target|ac}+?{AC Mod|0}]]}} Just copy paste that into a macro , I called mine ATK (keep the names short, trust me), make it appear in the bar at the bottom of your screen and voila! What does it do? When you run the macro it will first ask you to select a target, that means you click on a token. That token MUST have a value on their sheet called "ac". If you're using the Pathfinder 2e sheet it will have this. If your players filled it in correctly this value will be correct when unmodified. (No shield bonus, no other buffs/debuffs) Then it will ask you what the attack bonus of the monster is. Then it will ask if there's any mods to the players AC like it's shield is raised, or it's flatfooted. Just enter the total mod to their AC here. Then it does some math and rolls.1d20+the attack mod you entered, and displays the result, alongside the AC of the token you selected - the mod you entered. The fancy scary bit in the middle does the following: (d20cs>[[{@{target|ac}+?{AC Mod|0}+10-?{Attack Mod|0}, 20}kl1]]) That says "Roll a d20 but tell me it's a critical strike (cs) when it rolls higher than the number that comes out of the [[ ]] The bit inside the [[ ]] says Take the target token's AC and add the AC Modifier you specified. Then add 10 more. Then take away the Attack Modifier you specified. Then look at the total number you got and keep either 20 or that number, whichever is lower. So their Net AC + 10 is how high your total (roll+Attack Mod) needs to be for it to be a critical hit in Pf2E without rolling a natural 20. The kl1 part means it'll always be crit on a 20 even if they can't get a crit any other way. This can happen if their attack modifier is too low to roll AC+10 or higher. That's it! P.S. The whole thing is wrapped in the default template so literally anyone should be able to use the macro, free or paid accounts.
