Hello all! I am trying to make it so that when a player in my game rolls a nat 20 in my 5e D&D game the damage is the result of a damage die times 2 with their modifiers added. Is there a macro or system set up I need to use? An example would be someone rolls a nat 20, they roll a d8 and get an 8 so the critical damage would be 16 plus whatever their modifier is for that attack.
