If you're using a macro you can do something like: (Set yourself as BigBaddy) /me starts casting a spell to wallop the silly PC's /gmroll 8d10 And then tell them what happens manually. What would be nice tho, is to be able to set an Ability in a character sheet to the result of the roll so that you could do this: /me starts casting a spell to wallop the silly PC's /gmroll 8d10 == @Damage /me does @Damage to all the silly PC's That way the roll is hidden, but you announce the resulting number.
