Hi, so I just activated a 7 day champion that I found out that I like and would like to unlock it permenantly, is there a way to do so? When I try to unlock it, it says already owned but when I get an S it says that I need to own the champion to get it's mastery. I also have a skin shard for that champion, but since I don't "own" it, I can't use it.
**Can I fix this somehow or perhaps reverse the rental?**
