Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
(edited) This is a great build for Rammus I didnt put a sixth item that can be whatever you want but i suggjest Force of nature it gives you and little be more speed and you get a pretty good health regan. Also when playing as Rammus you want to get buffs there great ecpesical the golem buff because Rammus burns though alot of mana
