Mordekaiser

Innate: Mordekaiser's basic attacks are empowered to deal 40% AP bonus magic damage on-hit.

Innate: Mordekaiser generates a stack for each enemy champion or large monster damaged by his basic attacks or hit by his basic abilities, lasting for 4 seconds, refreshing on subsequent triggers, and stacking up to 3 times. At 3 stacks, he gains Darkness Rise.

Darkness Rise: Mordekaiser gains 3% / 6% / 9% / 12% bonus movement speed and deals 5 (+ 30% AP) (+ 1% - 5.47% (based on level) of target's maximum health) magic damage every second to nearby enemies. Against monsters, the damage is capped at 40 - 218.82 (based on level) per second.

Active: Mordekaiser strikes his mace down in a line in the target direction, dealing magic damage to enemies within, increased if only one enemy is hit.

Passive: Mordekaiser stores 45% of the post-mitigation damage he deals and 7.5% of the pre-mitigation damage he takes, reduced by 75% for non-champion sources, as Potential Shield on his secondary resource bar, up to 30% of his maximum health. The Potential Shield decays by 8 to 25 every second after not dealing or taking damage for 1 second. While Indestructible is not on cooldown, the Potential Shield will not decay below a minimum of 5% of his maximum health, and it will be set to that amount when it comes off cooldown if it was previously below it.

Active: Mordekaiser consumes his Potential Shield to grant himself a shield for the same amount for 4 seconds. The shield decays exponentially over the duration. Indestructible can be recast after 0.5 seconds while the shield is active.

Recast: Mordekaiser consumes the remaining shield, healing for a portion of the amount.

Passive: Mordekaiser gains magic penetration.

Active: Mordekaiser summons a claw in the target direction that grants sight of the area. After 0.5 seconds, it deals magic damage to enemies within and airborne them 250 units.

Active: Mordekaiser aims his mace towards the target enemy champion, slow them by 75% and true sight them over the cast time, and then banishing them with him to the Death Realm for 7 seconds. Mordekaiser also consumes the target's soul for 7 seconds, heal himself for 10% of their maximum health and reducing their current ability power, total attack speed, maximum health, armor, magic resistance, and size by 10% for the duration. Additionally, the target's base attack damage is reduced by 10% of their current total AD for the same duration. Mordekaiser gains the reduced stats of the target for himself for the same duration, and if the target dies while inside the Death Realm, he keeps their partial stats until they respawn.

Units between realms see each other as spirits, considering each other dead and negating any interactions between each other. Only Mordekaiser and the target will enter the realm; other champions cannot follow them. Everything that occurs inside the Death Realm is hidden to units outside of it, and vice versa. Most pets still inside the realm are killed at its end.

If one of the two affected champions leave the Death Realm, because of having died or having it dispelled, the other will do so as well.
