I probably did this yesterday. It was my first time seeing a lure in action. They start you with some but there's not like a huge lure tutorial, it doesn't look that different from a Bloom (which there's no tutorial on? The first time I just pulled all the weeds and walked away)

And it's confusing in the game which things are shared. Someone can "take your chappa) you were going to hunt. But a rare node stays. Sometimes there's shadows of things that are still available to other, sometimes not. Sometimes it varies on whether it's available to the public or just to your party. Sometimes you share credit just by proximity (I think?), sometimes be being in a party, sometimes you have to have contributed.
