You'll quickly discover that levelling up in Assassin's Creed Shadows is a remarkably complicated and annoying process. Not only do you need a bunch of skill points, known here as mastery points, but you'll also need to increase your knowledge rank.
Your knowledge dictates the highest tier of skills you can spend your mastery on, and it's a significant bottleneck to your progression early on. You'll be earning mastery points left, right, and centre since all that takes is XP–which the game hands out like candy–while getting knowledge points is much more involved. Don't worry though, I've included all the knowledge point locations under their respective sections below so you can easily increase your knowledge rank.
