it seems it works:
1, get legit 5 sox crystal swords
2, get legit runes: amn, ral, mal, ist, ohm
3, put into cs just amn, ral, mal, ist
4, let ohm be aside. looks like this:
5, this way placed on dupe char, you can dupe this.
6, then with other char in game, pick and finalize runeword. keep if 6 bo.
7, it seems nothing poofs. neither whole item, nor runes from inside of sword.
now how to make hybrid runewords, when nothing poofs from inside ?
tell me for example how eni of duress
so i tried to dupe just clean 5 sox cs, kept on same char. didnt poof
also tried dupe gemmed 5 sox cs (amn, ral, mal, ist), kept on same char. it didint poof
so for making 6 bo ctas, you need to find just one 5 sox cs and one set of legit runes amn, ral, mal, ist. put in, dupe until 11 pieces of this (it is full char - stash+inv) BUT you need all ohms legit.
but i didnt try how would it behave if you put duped amn, ral, mal ist into sword and dupe that again gemmed. and finalize with ohm legit or ohm duped. no idea.
ALSO i would like to know, what happend to item, when you fill in all socket holes in item. but not make rw, just put items inside. wouldnt it make item with ID ? but just and only when all sockets filled. so 1 empty will be no ID item and full socketed wil be with ID.
