Marco for Multiply Advantage and/or disadvantage

Working on make a sheet for Dragonbane and I was trying to figure out if this can be done with a Marco or if it would have to resort to a MOD script. Any help is appreciated. Multiple Boons/Banes: If you get multiple boons/banes to your roll, roll an additional D20 for each boon/bane and count only the lowest/highest result. However, please note that unless you have a very high skill level, rolls with multiple banes have a very low chance of success. Boon and Bane: Sometimes you might get both boons and banes to your roll. Each boon negates one bane, and vice versa. If you have one boon and one bane, make a normal roll (one D20). If you have two boons and one bane, it counts as a boon.

This macro should handle that for you [[ [[1+abs(?{Boons|0}-?{Banes|0})]]d20k[[{?{Boons|0}-?{Banes|0}+1,1}k1]]dh[[{?{Boons|0}-?{Banes|0},0}k1]] ]]

By the way, just as a note for the future, since you are making your own sheet you can do a lot of what can be done in a MOD with Custom Roll Parsing (though it might be trickier).

Thank you very much. RainbowEncoder said: This macro should handle that for you [[ [[1+abs(?{Boons|0}-?{Banes|0})]]d20k[[{?{Boons|0}-?{Banes|0}+1,1}k1]]dh[[{?{Boons|0}-?{Banes|0},0}k1]] ]]

Thanks for the info. I am just fiddling with it right now, but I will check that out. GiGs said: By the way, just as a note for the future, since you are making your own sheet you can do a lot of what can be done in a MOD with Custom Roll Parsing (though it might be trickier).
