Shield Master effect

[DocSharpe]

Sorry if this has been posted somewhere else, my search-fu skills aren't the best.

I'm trying to set up an action for a less technical (read: "typically confused") player. Essentially, the flow would be:

1. Contested Athletics checks between PC and targeted NPC.
2. Apply Prone condition.

I've got the second part down...I just can't figure out how to set up a contested skill check.

You cant do automated contested checks (afaik).

That's unfortunate. But thank you...I can stop digging now.

Alternatively you can have them dex/str save or go prone, much like how charging Minotaur attack works. I do this in my campaign because I feel like being hit or shoved with a shield would cause a reaction/save not a check.
