Tooltips, item comparison feature, enemy level display

I am loving the game so far but wish there were tooltips that dived deeper into the different aspects of them item (what is a rune? what is each rune’s effect? etc). There needs to be so much more detail.

Also if there could be an item comparison feature similar to Diablo, Dark Souls, etc that would be extremely helpful.

Lastly, can there be an option to display the enemy level?
