The GM in a game I'm in has given us an item with the effect "when you roll a 1 on this weapon's damage dice, you can treat it as the maximum instead." (It's a d10 weapon, but you could also apply damage bonuses to it). While I figure you can do this with a rollable table, does anyone know of a way to automate it using roll20's default dice mechanics? Our group has some pretty decent macro wizards but this question has defeated them.
