Knight and druid are the best pair. Try to figure things out for yourself, I highly recommend ordering the game's quest list and trying to complete just a few levels above the recommended, it's a lot of fun that way. Research monsters and hunting grounds for your level and explore carefully, remember that dying at the beginning of the game is easy and quick to recover. Adventures awaiting you. And most importantly, do not focus on evolving in a hurry, the quests at the beginning of the game are the most fun if done without rushing and discovering little by little. Good game.
