I have a Ronin at level 6. Its my understanding that when I reached level 5 I would be able to level up attunement. How is this accomplished. I do not see an option for it under enhancement. I see others with level 6 Ronin with attunement to level 4, so I know its doable. I have not been able to find instructions or a guide about it.
my eye image on my Ronin hero is open and has the number 0 in it. On my attunements tab, my attunement affects button is greyed out. On the first image you can see I have 52 shards presently. When my Ronin was level 5 I though by upgrading it that it would ask how to apply the shards, but rather it just upgraded my Ronin to level 6. I do not have an attune button at all. here are my screen shots below.
