Hello, so, I hope somebody could guide me, I need advice in my situation.

there was a season in which I was not a very active player, my schedules did not allow me to participate in most important events, I currently have that time but I would like to climb a little and make my account more competitive since I am very outdated .

I will leave a little description of my account.

I'm 97 lv about 80k power, I only have two lv 8 refiners, lv7 runes in a character, class A treasures, and spells lv 5 ~ 4.

please what should I invest in to improve and increase my power appropriately?

greetings and thanks.
