Given that you mention large upgrades I'm assuming you are thinking mainly of the Fe`Dhars.

You'll be way low at 49, tbh. The earliest I found it viable to solo them (aka. land spells) was at 57. This was as an enc, with tash. Buffed pet (shambling cube) -> tash/slow(/root) Fe`Dhar.

They hit hard, have a ton of HP and regen very rapidly. Unmezzable but rootable/slowable and does not summon.

The shambling cubes are somewhat easier and share some of the loot table, but I've never seen any of the items you're after drop from them.

Also. Stuff is rare. Like, really rare.
