Playing against Rammus

How to counter and exploit weaknesses

1

Magic damage counters him: Rammus stacks armor but is vulnerable to AP.

2

Do NOT auto-attack him when his W is active: every auto reflects massive damage back to you.

3

His Q can be blocked by minions or any unit — position yourself behind minions.

4

The taunt is targeted but short range: kite him and stay out of E range.
