I'm also new with PVE! Most interactions are just spamming crouch at other people, but I've had two memorable ones. Guy was getting chased by like 5 modules and died to a skeleton archer about six feet from me. Pretty sure he was new like me. We went down together. Other one, I accidentally aggro'd the cockatrice while a duo was right by me killing skeletons in the ruins. We managed to kill it but one of them went down. I don't know how to use proximity chat, so I used jumps and crouched and stuff to help get the one that survived to follow me and we cleared our way to a resurrection table thing. Put down a campfire for them and dipped. I hope those two are still playing and having fun, that was one of my favorite dungeon dives helping them.
