Runes.
A:
This won’t help much but as far as I can tell the runes are completely random. You can buy them from the TP or you can buy the exotic armor and salvage the rune out of it.

…. off the golemancer is only done by getting dungeon tokens and can’t be traded to other players.
I think it is easier to get (most of) the stats by going to a more crit orientated gear and use something like rune off the eagle or rune of the ranger for the precission and the last bits of crit damage. I didn’t calculated it but that way you should be able to get pretty close to the stats of the 6 runes of the golemancer (besides the golem spawning)
