a few hundred runs of the multi and then some more runs of the armor book event. Its a lot.
raw materials the limiter seems to be the sand for me. its 30 to build, 20/30/40/50 to awaken (i think). so your total sand cost is 63*30 + 15*20 + 7*30 + 3*40 + 50 = 2570 sand. average sand per run seems to be between 8 and 16 closer to the 8 side lets call it 10. So 250 runs.
What's the deal with these? I see them on lots of players? What stat's are good on them, and will they last through several updates as a good piece?
