This one is pretty simple, just make a Chat Menu button and put that in the description of the attack. In the Global Attack Modifier section: Click the Plus sign to create a new line Call it Precision Attack Set it to roll your superiority die value Drag it to the bottom of the sheet. Click the macro button it creates Click on the Chat window (where you type) Hit the "up arrow" on your keyboard. Copy the command text. It should look similar this: %{Charactername|repeating_tohitmod_-NZ6BCOLBKBZRj3M5Tw0_global_save} Next, go to the attack you want to modify, put this in your Description section: [Precision Attack](~Charactername|repeating_tohitmod_-NZ6BCOLBKBZRj3M5Tw0_global_save) Note how the % and brackets {} were stripped off of it when I put it in. Now you have a button you can click to add the Precision Attack after you make your attack roll.
