Iron Man: Mordekaiser generates a shield equal to 50 per level plus 15% of his maximum health. Damaging an enemy champion with an ability or killing a minion or monster charges the shield by 15%, doubled to 30% for kills or assists against an enemy champion.

While Iron Man is active Mordekaiser takes 8% reduced damage from auto attacks. %hp damage is calculated using Mordekaiser's current shield versus his maximum shield while Iron Man is active, not his health. The instance of damage which breaks the shield will not carry over to Mordekaiser's base health pool regardless of its strength. Upon his shield being Iron Man cannot be charged again for 7 seconds and is affected by grievous wounds.

While Mordekaiser is not in combat Iron Man decays by a rate of 1% maximum charge per second down to a minimum of 10% maximum charge.

Q Mace of Spades: Mordekaiser channels a swing of his mace for up to 3 seconds, initially slowing himself by 30% but gaining up to 30% bonus move speed over the duration. When Mordekaiser ceases charging he swings his mace in front of him, damaging the first enemy hit and knocking it back. The knocked back enemy does bonus  damage equal to 125% of the initial damage to enemies they pass through and slowing them by 20% for 1 second. If the knocked back enemy collides with terrain they are stunned for 2 seconds and take bonus damage equal to the original damage. Knock back distance and damage scales with channel duration. Mace of Spades goes on its full cooldown and cost even if the channel is interrupted.

W1 Creeping death: Mordekaiser summons a vortex of shrapnel and spirits around himself, an ally unit or enemy minion, dealing physical damage per second for up to 6 seconds while charging his shield for 25% of the damage dealt and stealing the resistances of enemies caught in the vortex. If cast on an ally champion Mordekaiser grants them a shield equal to 15% of his total iron man shield for the duration of Creeping Death and they receive resistances equal to 50% of all resistances stolen.
