Humanydyne dice macro

Hi, I'm new to Roll20 and would like to know if that's possible to make dice success count for Humanydyne. Basically the rule is to roll some d6 and sum : 1    = -2 3,5 = -1 2,4 = +1 6    = +2 I saw you can count a value with =, but didn't see if it's possible to count several values. Also I can define 6 and 1 as critical success/failure adding cs6cf1, but that doesn't really affect the count :( For failure it'll probably be the same with the "f" The last part is about critic "counting double". Thanks in advance for any help.

Is there any reason to have the actual numbers rolled, or would it be sufficient to have dice whose faces are effectively -2,-1,-1,+1,+1,+2 ? You could set up a  Rollable Table with the above distribution quite easily and then just roll those.  After setting up the table, it might look something like this: /roll 3t[Humanydyne] or /me rolls [[ 3t[Humanydyne] ]]

Thanks for your fast answer, You solution works pretty well, but the thing is we really like the "throwing 3D dices" feature (especially when we're recording the map for streaming/videos), and you loose it when using rollable table. You can add icons to simulate dice, but then only the result appear in the chat :/ We're not throwing more than 10 dices actually, so we'll probably continue to count manually if no other solution, and use the tables if we need to throw a lot for any reason :)

Yeah, if you want to see the 3d dice, you'd either need an API script to post process the calculation, or come up with a formula to get the right values (which could be done, I'm sure, but would need to be repeated for each die and would not be something you'd want to type in).
