Yes, there is, but as a fair warning, it's gonna look a little weird. There are two ways to do this, and it's going to depend on how you have your sheet set up. The first way should only be used when you have your sheet set to auto-roll damage and the attack at the same time. Add the following to the very end of whatever you have in your description field on the sheet for your attack: }} ?{Assassinate|No, |Yes, {{crit1=[[@{dmgbase}]]}} {{crit2=[[@{dmg2base}]] } This works because the description field is auto wrapped in {{ }} by the sheet when it is output to chat. So, you're just taking advantage of the presence of the ending }}. If you don't have a 2nd damage type, you can leave off everything after @{dmgbase}. If your weapon does a custom amount of crit damage, you can change @{dmgbase} and @{dmg2base} to @{dmgcustcrit} and @{dmg2custcrit} respectively. Now, if you have your sheet set to not auto-roll damage and crit (have to click on the weapon name in chat to roll the damage), you'll want to slightly modify the above, otherwise you will be prompted for your damage queries twice. If this is the set up you've go, enable ammo tracking on your sheet settings tab (you don't need the API for what we're going to do). After ammo tracking is turned on, there will be an ammunition field added to your weapons on the core tab. Add the following to the end of that field: ?{Assassinate|No, |Yes, {{crit1=[[@{dmgbase}]]}} {{crit2=[[@{dmg2base}]]}} } This works because the ammunition field is inserted after ammo= in the sheet generated roll template, but is not wrapped in {{ }}.
