Need help with macro that makes arcana roll and sends it to rollable table.

Guys, I am tired of the easy magic item identification rules in 5e.  Therefore, I want the party to roll on the DMG's alien technology table to figure out magic items. I want to use the Arcana skill instead of straight intelligence. I know how to make the table a rollable table, but I don't know how to create a macro that will roll the selected characters arcana and use the number to get a result from the table. Help?

There isn’t a way to do that without the API. Powercards might have an option for this, but I know there is one specifically designed for it. 

Here's one:&nbsp; <a href="https://app.roll20.net/forum/post/1408851/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/1408851/slug%7D</a>
