Mordekaiser Ability (LoL): Iron Man

Mordekaiser shields himself for 25% of the damage dealt from abilities, absorbing incoming damage (shield generation is only half as effective against minions).

The maximum shield strength is equal to 25% of Mordekaiser's maximum Health, while the shield decays by 1.5% of his base Health every second. Once the shield reaches 25% of its maximum value, it no longer decays.
