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.
Basically same build as Nespabo's with a little more balance towards Magic Resist and change in runes to be at his max at lvl 18. If You're enemy team is a majority of melee fighters instead of casters then follow this link to Nespabo's build of which I got my Ideas: http://www.mobafire.com/league-of-legends/build/rammus-killer-852 Rammus will be your high Damage dealing tank. Rammus doesn't have much health but his survival skills are quite sufficient. Enjoy :)
