Playing against Amumu

How to counter and exploit weaknesses

1

Amumu is very vulnerable to early invades — his 1v1 is weak without both Q charges. Invade his jungle at level 2-3.

2

Spread out in teamfights: his R stuns everyone in the area. Don't stay grouped up.

3

If Amumu uses both Q charges and misses, he has no gap-closer for ~12s — that's your window.

4

Buy a QSS or take Cleanse to cancel his R if you're a carry.
