hi guys! i’ve recently came back to genshin and he’s my first five star im trying to build. im pretty new to the whole artifact stuff, so i tried my best for a couple of weeks to farm good artifacts for him, but lose on how i can make my ranking higher. i can see that def is a problem i need to solve and i need to increase crit stats, but i don’t know where to start. thank you guys in advance!!
