Via Bioware: Our first new Companion Character since HK-51, Treek, arrives with Game Update 2.3: Titans of Industry. This mysterious alien mercenary is available for all character classes, and can be earned in-game or purchased directly from the Cartel Market. To help clarify these different options, here is an explanation of the different means to acquire Treek.
All methods begin with acquiring Treek for a single character:
From the Cartel Market:
The first step to gaining Treek is to purchase the Mercenary Contract from the Cartel Market (2100 Cartel Coins). This is a single-use item which will start a quest. Completing this quest will earn that character Treek. In order to complete the quest, you will need to be at least Level 10 as it takes place on the fleet.
With In-Game Credits:
The Mercenary Contract is also available from the astromech Legacy Vendor located in the new Cartel Bazaar area of each faction’s Fleet. This version of the Mercenary Contract requires a Legacy Level of 40 and costs 1 million credits. As above, using the Mercenary Contract will begin a quest and your character must be at least Level 10. Completing the quest will unlock Treek for that character.
Note that both versions of the Mercenary Contract can also be traded on the GTN. The non-Cartel Market version will still require Legacy Level 40 to use, so be sure to check which version you are buying before completing the transaction!
The Mercenary Contract (either version) will enter that character’s Collection when used – both versions unlock the same collection item. Completing the quest granted by the Mercenary Contract will also grant the Treek Legacy Unlock, a prerequisite for the Treek Character Perks.
Having acquired Treek via either method, you may now choose to obtain her for other characters on your account.
The Mercenary Contract can be purchased as an account-wide unlock (like any other item) after it has been unlocked by one character on the account (700 Cartel Coins). Doing so will allow any other character on the account to pull down a copy of the Mercenary Contract, which can be used to start the quest as above.
Once one character on a Legacy has completed the quest and received the Treek Legacy Unlock, any other character on that legacy can purchase the Treek Character Perk for the appropriate faction, which will instantly grant that character Treek as a Companion without needing to complete the quest again. The Character Perk is purchased with in-game credits (300,000) and requires Legacy Level 40 and Character Level 10.
