My account has Diluc, Xiao, Kazuha, Yelan, Itto, and Nilou (only lost 50/50 twice). Finished Archon quest on Mondstadt, Liyue, Inazuma, and Chasm. Also have 2 5 star weapon, Skyward Spine and Atlas. Already have 29 pity but 50/50. Diluc, Kazuha and Yelan is fully built already just need to max out their talent and level.
