You get your free lv 89/90 AF gear, and dungeon accessories. That's plenty enough for retainers.
I tried that and it said "owned", wont let me get a second set.

If you can wait a few weeks, the crafted combat gear is coming. (It might even come on tuesday, I don't remember if it drops at the same time as the normal raid or savage raid)
I can, yeah, and muchly thank you.

*puzzled*

if you hand off a set of AF gear to the retainer, will the vendor allow you a second set, thats what I dont know.

Well, in shadowbringers you could just get multiple free sets of AF gear. I haven’t gotten to 90 Endwalker yet, so I can’t say that’s true here, but check into that.
Ill try. Again, thank you.
