Amumu's basic attack will then reduce his target magic resistance by an amount depending on his level, this debuff will stay on the target for 4 seconds, it cannot stack to reduce the target's magic resistance by more than the stated value, but the timer will refresh every time Amumu hits the target.
No ability in-game will protect the target from the debuff, even if a shield protects the target from getting damaged by Amumu's attacks it will still receive the debuff.
Amumu's basic attacks will not break spell shields, his passive will apply through the shield.
The debuff is an On-Hit Effect so it can be dodged or blocked by Aegis Protection.
