When I try to drag and drop tier 1 runes into my book, the icons don't move and nothing happens. I asked a lower level friend to try it, and it worked fine for him.
I get the feeling I'm missing something really obvious, am I just overlooking something?
You can only drop the runes over slots that you've earned through leveling your summoner. At level 1, you only have one red rune slot to use, for example.
