Currently, when on the equipment tab you can select any of the main 6 pieces of equipment and it will show the legendary rune(s) you have crafted in the armory screen. The armor pieces light up blue and you can drag the rune into the armor as you would expect.
This is not the case, however, when selecting an upgrade for an aquabreather.
The breather doesn't get a blue highlight and it doesn't show up as an option under customize for the aquabreather. My guess is that this is an oversight with the Armory, not something I'm doing incorrectly, but would like to confirm if anyone else is having this problem. I specifically crafted this rune so that I could use it in aquabreathers and never have to worry about missing out on the capstone while underwater.
Yep! That's what it was! I had lv 60 aquabreathers for some reason. I didn't realize you couldn't slot legendary runes in those.
