Dont use HQ crystals on these to try and prevent break loss. They are 100% break loss with or without HQ crystals. I learned the hardway after buying 120 HQ crystals for the sake of science.....
I recommend using a Goldsmith's Escutcheon on these. This item can turn into a Koh-I-Noor if you're very lucky. And Koh-I-Noor makes Stikini Ring +1, which has always sold very fast and is currently being spammed more than usual for nefarious reasons (there's a packet manipulation leak right now and items like Stikini Ring +1 are much easier to make if you're a terrible human being because you can just tell the game what items, if any, you want to lose during any broken synthesis).
