Help a noob plz

Yoooo! So I started playing this game like a week ago and now can't stop playing it and learn what the game has to offer im now fully maxed lvl175 plasma conjurer but I really don't know what armor pieces to get and mainly where to get them, I know I can get sunken armor I think? In the deep sea or wtv it is called but just wanna make sure if theres any other armors that could be useful too!
