Rammus is a spiked shelled armadillo that came to life one day and seems to be sentient but its vocal cords only have the capacity to say "O.K.", it is not known what O.K. stands for but seems to have some meaning of agreement.

Rammus in the top lane may seem weak but in the hands of an at least mastery 3 Rammus player using this guide and build it is unstoppable.

You get Boots of Swiftness first because Rammus is useless when he cant get to the enemy. Ramuus's early lane pressure is insane as long as he is able to get to the enemy. You then get Hextech Protobelt-01 because it is good ranged poke and further increases your ability to get close to the enemy. Dead Man's Plate is obvious as Rammus's basic attacks can proc its passive. Finally, Rylai's Crystal Scepter is extremely good because the enemy will not be able to escape you unless they have flash up.

Righteous Glory allows you to gain a sudden burst of movement speed that the enemy will not expect as long as they don't look at your items.

Youmuu's Ghostblade is similar to Righteous Glory but it also gives you out of combat movement speed and its active allows you to ignore unit collision, you might think that ignoring unit collision is bad thing on Rammus since you won't be able to hit the enemy with your Powerball, but don't worry, it only ignores unit collision with allies.

Liandry's Torment is for the Rammus player that hates life and needs a way to hide their bloody tears from the world but still want to express that they are crying tears of blood from armadillos gouging out and infesting their eyes.

Ohmwrecker is for when your enemy laner grows bored of dieing to you constantly and then you get bored of the game and want to move it along quickly. Use it to destroy towers in a timely manner in accordance with your Tremors which deals damage to structures.

Zhonya's Hourglass allows you to deal damage to the enemy with your Tremors without being able to take any damage, this works very well with Rylai's Crystal Scepter because they will find it difficult to escape your Tremors. Zhonya's Hourglass can also be used to take towers with your Tremors when no one is looking.

Boots of Mobility is a rare buy but necessary if you somehow find yourself dieing to the enemy laner, you will need to be able to get back to lane quicker to kill the enemy.
