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.
Skill sequence varies for depending on if I have 2 melees or 2 range/ 1 ranged 1 melees. If I have two melees in the lane I max out taunt asap simpe bcause it owns melees. If I have 2 ranged or 1 ranged I go with shield first for protection. but always save roll for last. Taunt is very effective for bring melees into towers.
I play almost every game with cleanse and ignite, personal preference. his ult has a fairly low CD so I will use it on big creep waves to farm. This rammus can carry a team if used effectively.
Its a basic, but very effective tank and player killer all at once, basically use powerball to intiate then taunt, shield, ult. very basic. Cleanse gets you out of tricky situations.
