Setting up some magic weapons need a bit of help
 

The Artiticer Infusions include some new magic weapon qualities (Repeating, Returning specifically for my needs) and the weapon choices aren't so much swords or axes or even Martial vs simple. It's weapons with the thrown property and ammunition property. Is there a tag for those? If not I'm not really butt hurt about it, but I was gonna check with the experts.

I'm pretty sure you can just use wProperty.Thrown or something like that. Those sorts of tags should exist on the weapon Things themselves, so a tag expression will catch them.

Also, I know Mergon programmed a lot of the Infusions as adjustments. You should be able to enable them with the UA Artificer 2019 source.

I went and double checked. They are, thankfully, this straightforward: wProperty.Thrown and wProperty.Ammunition. I played around with tag expressions a lot for the new Monk Weapons Class Feature Variants, so check out cMnk5CWeap if you want to see what I did for that. You can also check out how Mergon did the Repeating Shot adjustment, p5CArRRepShot.
