This zone is HUGE, so be ready for a lot of running or use of warp. If using warp, please be aware of other players that may be fighting in this zone. This zone is VERY straightforward other than the fact that it's a GIANT MAZE. Your only objective is to collect 6 runes from the 6 bosses that inhabit this zone.
Upon completion, you will receive the Earring of Immortality Rk1
Recipe :: Progression Seal: Mastery of All
Combine all 6 runes inside your Universal Assembly Crate to create Seal: Mastery of All, and turn that in to Borat to receive your Earring of Immortality Rk1.
To upgrade this you will need to combine an Epic Gemstone of Immortality with your Earring of Immortality Rk1 to get Earring of Immortality Rk2. Continue upgrading that way until you get rk15, which is called Earring of Immortality - Complete.
