The Aaron said: The global modifiers would be useful for temporary or overarching bonuses granted by a spell or magic item. For example, Bless gives you a +1d4 to all attack rolls and saving throws for its duration. Rather than adjusting every attack and every saving throw to add that in, you could just add the roll once globally as a bonus to all attacks and all saves. Haha, thanks, man! Again... Roll20 could have "Thanks" option on thread's comments.
