Bone Studded Bracelet
from one of the named mobs in The Grey. You could solo this right now, it's just a hassle to get the named to spawn.Shai`Din Revenant Bauble
from the Battlemaster in Chardok.Fancy Velvet Mantle
from the Observer in Chardok.Girdle of the Bloodfiend
from one of the Vamps in the TM Castle. You could definitely solo this in a couple levels.Sinew Tied Earring
from mephits in PoN. You could solo this in a couple levels, it's just tricky getting to the camp.Honorary Faceplate
from one of the undead in PoV. You could also solo this in a couple levels but the named is rare and the drop is sort of rare, too. It's really one of those drops you just sort of luck into while exping and use if you don't have anything better.Band of the Visionary
will drop eventually if you do enough PoV razorfiends groups.
They aren't great items, truth be told, and it'd be tough for your character to pick them up solo. The Girdle you could probably find in the bazaar for cheap, and maybe the bauble too. There's a bunch of PoP stuff available for casters, but most of it is either on mobs that are a hassle to kill (and not killed that often because of it) or relatively trivial for certain groups (and killed constantly).
