Macro: Roll two d10's, add if equal, else take first?

Hello, I'm trying to write a macro for a game, and I am unsure if Roll20 can support this. The mechanic works like so: Roll 2 different d10's, let's call them A and B. If the results are different you add A to the appropriate ability and give the result. If both A and B are equal, you add them both to the result. Example: I roll 7 and 9 plus my Strength 5. Result: 12. Example: I roll 7 and 7 (a matching pair!) plus my Strength 5. Result: 19 How do I write a macro to automate this roll?

Got bad news and good news for you. The standard dice roller doesn't support that type of macro. You can use the api (mentor level feature) scripts to do that more then likely.

Just to verify: you can do this with the API.

You can't do it directly as such (there's no way to make multiple references to the same roll in a formula), but you could set up a rollable table with 20 entries (ten entries of 1-10, each with weight 9, and ten entries of 2-20, each with weight 1) or you could do something like 1d10*(1+{1d10-9,0d1}kh1). Both of those give you the same probability distribution, although neither will appear the same on the table.

Thanks for letting me know!
