About Rings on Reboot

Can these be potential'd? If so then they might be worth considering although they're pretty pomegranate unless you have both of them together.

Yes, but crafting them is a peach, so it might be more worth it just to get other rings and NPC the materials.

I think the recipes might not be completely accurate anymore, but since the last time I've crafted these, you do need at least 1 primal essence for each ring, which is pretty rare.
