Aside from LOTR/The Hobbit what are the best, most quintessential fantasy books/series that everyone should read?

I'm not including fantasy romance or romantasy in this. I only want strictly fantasy books/series. It's fine if there's a romance subplot but I'm not looking for romance novels here. I want to know what you all think are the top fantasy books/series of all time that deserve to stand among the likes of LOTR. I'm looking for the best of the best here. Give me your absolute best five star recommendations!
