League of Legends wastes no time in changing over from season to season. Worlds has just ended and now there is a massive amount of content up on the public beta environment to get us ready for season 6. As usual, this season brings new masteries and this time, the layout is extremely different, so over on the next page, Jeremy Curious Gaming has a video guide to the new Keystone masteries. The mastery system in League of Legends give your champion some minor passive boost, whether it is some extra damage, extra gold, or extra health, these background boosts are very helpful, but are quite streamlined depending on your role. This new Keystone mastery system seems to be very customizable and a lot different than before. Take a look and see how this system has changed and get a head start on Season 6!
