The obelisks drop five patterns (types) of data: Alpha, Beta, Gamma, Delta, and Epsilon. The drop rates for the first three are common; the last two are super rare. Naturally, you need the most of the rare ones, and there are no traders for Guardian materials or data. The one redeeming feature of this grind is that you can gather everything you need at once; your data storage will hold enough for every unlockable at once.

You'll need data for the following modules:

• Guardian Hybrid Power Distributor: Alpha

• Guardian Hull Reinforcement Module: Beta and Gamma

• Guardian Shield Reinforcement Module: Delta

• Guardian Module Reinforcement, Guardian Hybrid Power Plant, and all 3 Ship-Launched Fighters (XG7 Trident, XG8 Javelin, XG9 Lance): Epsilon

To unlock everything, you need the following quantities: 20 Alpha, 34 Beta, 16 Gamma, 24 Delta, and a whopping 114 Epsilon. The last two are the only ones that matter, because they'll take far longer than the rest. Epsilon, particularly, splits 15 for the Module Reinforcement, 21 for the Power Plant, and 26 each for the fighters. You will log and scan and log and scan and log and scan and log and scan for a couple of hours to get this done. Alpha through Gamma types will max out storage with completely unusable stuff long before you get within shouting distance of completion. I've gone as much as 20 to 30 logins (40 to 60 scans) between drops of Epsilon (or Delta) data. But then you'll be done and you'll never need to farm this particular farm again.
