I know this has come up before but I can't find quite what I'm looking for. So here it is (again)
I have a friend in the game that has helped me so many times, I can't even begin to count and I would love to gift him some crowns. Is there a way to do that without his information? I know I can gift him items, but I wouldn't even begin to know what to gift him that he would want or doesn't already have.
I'm not sure if you can gift crowns, but if you want to give him something, maybe approach him by saying, "I appreciate all the help you've given me and want to give you something as thanks. Is there something in the crowns store that you'd like?" Maybe you can help him farm dungeons as an alternative.
