Yes i'm speaking about Raja's, Tama's and Satava's,
however it doesn't end there (nor will i speculate on stats),
rather the DM Earrings, Apoc Nigh Earrings, Evokers Ring and Toau Rings
need an update too.

I wouldn't want that for free however. Nice Storyline based Quests should be going with the Upgrades.

While on COP Rings there was an answer a while back....

....there was nothing about the rest.

Evokers quest is by far the most easy to see as in Kill Alexander, Odin, Caitsith and Atomos for 4 Upgrade Items to get the ring to the new Stage.

The rest is pretty unclear atm :P

But! Don't you want them upgraded rather then have the rotting in your Mogsave?
