What are all the rune specifications? I noticed the frames with 4 spikes can be greater or superior. Also that there are such things as heroic and legendary. And stars.
Legendary, heroic, (all the lowers)- are these the silver frames?
lesser, improved, greater, superior, elite- do these have visual indications?
and are there any I don't know about? It seems there are lots of factors that go into runes.
