Just do Celestials. I got my set legs already. Chance for loot is 25% per roll. Since you should coin it is even higher.

“Do not lose time on daily trivialities. Do not dwell on petty detail. For all of these things melt away and drift apart within the obscure traffic of time. Live well and live broadly. You are alive and living now. Now is the envy of all of the dead.” ~ Emily3, World of Tomorrow
