Do Bondsmiths Capture the Unmade in a Gemstone?

Only bondsmiths would be able to perform this action of trapping the unmade in a gemstone. I think dalnar does it at the end of oath bringer, right? Yea, that's correct. Helite conquers the thrill, and brings that into the gem stone that had been brought, i believe, by odium. And then lift and night blood need to go ge lift zeth and nighta. So that puts him in an interesting position, as, you know, the only one that has this specific power.
