Ah yes, the moment I got Ganyu's AA to lvl.10 was the moment I found out how really broken she is, and that is with subpar artifacts. Still need to get a 5-star Cryo Dmg Goblet and Crit Dmg Circlet with better substats. That and I got lucky when I got Skyward Harp in a single roll in the Permanent Wish banner.
My first waifu on GI.. And forever will be my #1. Crowned 3 of her talents, with her Amos' Bow, nuked more than 40k-50k charged shot everyday excluding elemental reaction. I'm so happy with my own achievements but i still have long way to go while hunting her better artifacts.
