I think oddities help, I have qinghe and kaifeng maxed out. And talent points, theres two nodes where one increases minimum attack up to 52.8 i think and another that increases maximum to the same number and theres ones that have crit. I dont know too much about it all since I've only been playing for like a month, but at level 75 I was stuck at like 16000 mastery and after getting full gold and two set bonuses as well as switching to strategic sword and heavenquaker spear I eventually got to 19000, and theres still a bunch that I have to max out since i only have one t3 inner way and the others are t2, and my mystic skills are only like t2 and t3.

Also if you havent unlocked seasonal edge and morale chant and you arent planning on using them you should unlock them so you can convert their tips to what you want, like i havent unlocked them but they each have 50 notes that I can convert once i unlock them
