Wow, my luck is incomparable.
I clear all 12 stages in survival trial + all 3 stages in Trial Breakthrough (lvl 64) everyday. I only use 4 ninjas (my main team) and can finish them with almost full life. YET I GET NOTHING FOR 2 MONTHS.
Temari x2 was the ONLY ONE TIME I ever got fragments or any special rewards T.T
May the game bless me.
