WhyAftershock

Rammus is all about engaging with the CC of his [Q] and [E] and the taunt should last long enough to keep your target in the explosion radius.

WhyDemolish

WhyConditioning

Rammus benefits massively from both Armor and Magic resist, scaling his [W] to make him an unkillable machine.

WhyUnflinching

WhyCheap Shot

WhyRelentless Hunter

Relentless Hunter's stacking Movement Speed combined with your [Q] allows you to get to any fight or skirmish on the map at the drop of a hat.
