If scripts are available, the Metascript Toolbox would approach it like this: !&{template:default} {{name=Proof of Concept}} {{Base Roll=[[15d12]] }} {{Showing Dice= {&eval}getDiceByVal(--$[[0]] --<13 --included --list|", "){&/eval}}} {{Failures={&eval}getDiceByVal(--$[[0]] --1|7|11 --included --count){&/eval} }} {{Successes={&eval}getDiceByVal(--$[[0]] --2-6|8-10|12 --included --count){&/eval} }}{&simple} If scripts are NOT available, there might be some dark sorcery Rainbow might be able to pull off, if you are willing to pay the price*. I'll see if I can summon them. * -- I am being told there's no actual price.
