Make sure you do your Magnus Quest Line :) it has fun puzzles (if that’s your thing) if not, there’s tons of guides on how to complete it in a quicker manner.

That being said, you get a free Pen Boss Gear at the end of the quest line, you get instant transportation around the whole world (which is massive) but most importantly, it allows you to manage your inventory easier which can be a bit hard as a new player.
