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.
1. This build is intended to use against a mixed set of enemies. Heavy AD, AP, or CC groups would require a different build. As always with a tank, your build is contingent on the composition of the opposing team.
2. I did include a fun build to oppose a heavy AD team. Which is Rammus' specialty because the more armor you have the harder you hit. With this build your base damage will be over 200 + increased crit + attack speed + movement = really mean Rammus/tank.
