To obtain this set you must.
1) Complete the introductory quests to be able to run ME with runes.
2) Grind for armor to restore and different Resonances to create crystals (10 per crystal) for MEs to obtain Rune Etchings.
3) Once you have 5 Rune Etchings of the same type you can exchange them for a Rune-Etched Orb.
4) Grind for the Resonance you will need for the restoration. About 1200.
5) Purchase an Energy Sealer for 100,000 AD
6) Use the items you have collected and 25,000 AD to restore your piece of armor
7) Repeat steps 2-6 for each piece of armor.
Total cost in AD 500,000. Total cost in time, who knows. This gear is 965. I have 950. Why should I bother?
Considering the best armor always goes in group content, makes you wonder how you feel about solo players.
