The world of Assassin's Creed Shadows is a massive one — in fact, one player found an entirely new and useful menu after not noticing it after 80 hours of playtime, earning the thanks of several other community members who also hadn't noticed it before. The discovery only went to show how much there is to uncover in the Feudal Japan-set open-world game.
Reddit user Affectionate-Bus927 found a new skill tree menu to acquire various global passive skills by selecting the knowledge rank button in the bottom left of the mastery menu. Many people in the replies admitted that they didn't know this menu existed, as how to access it isn't especially obvious. The top comment in the Reddit thread by Aussiemike90 echoed the sentiment of these players: "I did not know that. Thanks for the PSA."
It's important to note that this new skill tree can only be accessed upon reaching Knowledge Rank 6, which is the highest rank achievable. Upon unlocking this menu, Assassin's Creed Shadows players will be able to spend mastery points on some helpful global passive buffs to both damage and speed.
However, also remember that mastery and knowledge work differently....
