New to the game

Hi! So, recently I started playing BnS, I always wanted to play it but now I'm able to do it, but I'm kinda lost with what I need to do, how stats work, combos with my class(I'm maining a Summoner, she's lvl 16 atm) I tried to search for a begginers guide here in Reddit and also in internet but I'm not finding anything new, just guides from 2016 or so, also I have some other questions about the game but learning to play it first is important to me, thanks in advance
