Three tiers of Level 50 PVE gear appeared in the 11/26 patch: Tionese, Columi, and Rakata. Darth Hater spent some time poking around in-game and analyzing client data to attempt to determine how one could acquire some of the highest item level gear sets. All items included two- and four-piece set bonuses that curiously displayed only when the item is equipped; these set bonuses were mainly buffs to existing abilities and not unique to a particular tier.
So far, set names remain consistent to combat role through item progression, and carry a unified look throughout so you dont look mismatched or out of place. Armor set names were the same for both factions, and we do provide some low-res preview images of both the Imperial and Republic versions of the sets on each class pairing page. It is confirmed that the Republic versions of the armor sets look different, and keep in mind Imperial Agents use knives while Smugglers use shotguns.
We would like share what we found, and encourage comments if you believe anything is inaccurate or have any additions, as were happy to credit you for any legitimate finds.
One thing we noticed about purchasing end-game PvE items is that the off-hand weapon cost is less than the main hand cost. Dual wield classes can potentially pull the off-hand mods out and place them in their main hand weapon, and avoid purchasing the main hand weapon entirely to save up for a different piece. Bracers, belts, relics, ear pieces, and implants are missing from the vendor set, and may be acquired elsewhere along with schematics bearing the Tionese rank.
In addition to hard mode Flashpoints, we confirmed the normal difficulty mode of Eternity Vault yielded the necessary items to purchase Tionese gear:
The next tier of gear is Columi, as the pieces bear higher item levels than Tionese and although guilds reported they acquired them from Karaggas Palace normal mode, the datamined tooltips say they are from hard mode and nightmare mode Ops. Intended or not, we also had Columi items appear in PvP reward boxes. Columi gear is vendor purchasable via Columi Commendations or dropped item tokens containing the unassembled Columi prefix. Off-hand or main hand weapons, bracers, belt, ear pieces, and implants are not purchasable using Columi commendations.
The highest tier is Rakata, and both helms and schematics dropped from hard mode Karaggas Palace. All armor set pieces and weapons that were purchasable from vendors required a token turn in and not commendations. Rakata level implants and ear pieces are vendor purchasable for 120 commendations, which come from Ilum daily quests and turn-ins.
