[Request] Grab roll result and multiply it by attribute, then send new result to chat (leaves [[(10d20)/10]] roll result, adds [[(10d20/10)*X]] roll result)

I have no idea how to do this. I've looked for scripts that might have the functionality and I've tried looking at the Wiki and various examples, but it all just makes my head spin. I don't know Javascript well enough to interpret much of the code, much less write it myself. I'm running a game in which we're using (10d20)/10 as a method of centering/weighing the dice rolls toward a result of 10. The DC system is then based on an opposed roll, or an assumed roll result of 10. The critical part of the system is that the roll results are multiplied by a percentage, which is stored as an attribute (e.g. (@{Tyrion|Concentration})). However, multiplying the (10d20)/10 result by a percentage as complex as something like 0.26471 makes it difficult for the player to know what they rolled, which makes it hard to tell when they should use a Luck Point. So, I'd like to have an API script that collects (10d20)/10 roll results and multiplies them by the attribute, and then outputs the results (rounded, not base, ceil, or floor) separately from the original (10d20)/10 result output, such that a player can see both the total they rolled out of 20 (e.g. 10), and the multiplied+rounded result (e.g. 3). At the moment, the method I have of doing that is to have the player roll (10d20)/10, then to use a very long and complicated macro to input that result into a query, choose the relevant stat for the relevant character, and output that result to the chat. It's certainly doable, but it would save a lot of time and prevent a lot of mis-clicks and mis-types if I had a script that automatically did that work for me. Ideally, I'd like a script that would use syntax like this: !result-multiplier --multiply [[(10d10)/10]] Tyrion Concentration Again, I have no idea if that, or something like it, is possible. I'm just trying to find out my options, and see if this is so easy for someone that they can just modifying some similar code that already exists but that I don't know about. Thanks for your responses!

Would something like this work as a workaround? /r round([[10d20 / 10]] * @{Concentration})

It doesn't allow the player to see what their result out of 20 is (e.g. 10.2). I really just wish roll20 had a way of storing a roll result as a variable. That way I could just call it and re-use it in a macro like ~{save1|[[round([[10d20 / 10]])]]}    //where ~{x|y} stores result "y" as an attribute "x" [[@{selected|save1}]] [[@{selected|save1} * @{selected|Concentration}]]

Oh man. I'm so used to using templates that I didn't even remember what using the basic roll function looks like. Thanks!

You're welcome! Additionally, here's a macro using PowerCards that might do what you'd like: !power {{ --name|Sample Macro --Roll result:| [! [^R] !] --Calculation:| [[ round([$R] {10d20 / 10} * @{Concentration}) ]] }}

Hmm. I'll mess around with PowerCards and see what I can do. Thanks again! :)

Also, as a note, you can always hover over the output of anything in [[]] to see what the results of the specific rolls are
