Rolling Fate dice and keeping (-)

Hi, I prepare macros for an Earthdawn Age of Legend party and a i have a question Is it possible  to roll fate dice and count -1 as  successes ? The macro /r ?{malus dice?}df=(-1) dosn't work. Sorry for my poor english, i used un translator. Thanks

If youre rolling fate dice, and treating negatives and positives, this is the same as rolling a d6 with these sides: 0,0,1,1,1,1. In roll20 you can simulate that as (n)d6>3 So your roll would be /r ?{malus dice?}d6>3 If it's important to use fudge dice, you can get the same odds using /roll ?{malus dice?}dF>0 This roll treats 1 and 0 as 1, and -1 as 0. It's the same odds as treating 1 and -1 as 1.
