Well technically the game had gone 2 "days" already (first day was after maintenance, then the first reset happened 1~2hours later). We managed to get like 20 on each difficulty before the first reset. Approximately within the first 4 hours of the event, we already got Lilim Luxuria and some SR/SSR weapons. (:gogo:)
It all depends on what element you desire. A sample is now it's a fire hime gacha, if you want fire team, you should try your luck now. Regardless of the statement earlier, I recommend to save your jewels for the upcoming limited edition himes.
