If Mordekaiser kills his target, he will keep any stolen stats for the remainder of the round.
If Mordekaiser is in the Death Realm with the target dummy on the shop platform map when the combat phase ensues, he is immediately forced out of the Death Realm, ending the ability prematurely.
The Ring of Fire is special-cased to not apply its effects against units inside the Death Realm.
In the Reckoner Arena battlefield, the pillars will stay visible and will behave as normal inside of Death Realm, with the exception of them being untargetable.
Twilight Shroud will follow her between realms.
This bug was fixed on patch V14.1, but it is still present in Arena.
If someone who enters the Death Realm has the augment Chauffeur, their hitbox will follow their ally, while they appear to stand still at the position where they entered the Death Realm.
Abilities
PassiveDarkness Rise
Mordekaiser gains a powerful damage aura and Move Speed after landing 3 attacks or spells against champions or monsters.
QObliterate8/7/6/5/4s
Mordekaiser smashes the ground with his mace dealing damage to each enemy struck. Damage is increased when hitting a single enemy.
WIndestructible12/11/10/9/8s
Mordekaiser stores damage he deals and takes to create a shield. He may consume the shield to heal.
EDeath's Grasp16/14/12/10/8s
Mordekaiser pulls all enemies in an area.
Only when they cast an ability, will they visually teleport to their real position. Once the cast of that ability is over, they will visually teleport back to their original position.
If the ally of someone who enters the Death Realm has the augment Chauffeur, this ally will follow them into the Death Realm.
This ally will only follow the main target out of the Death Realm if they are currently attached or once they reattach.
That means that if they have a way to permanently deattach from their ally, they can permanently stay in the Death Realm.
RRealm of Death140/120/100s
Mordekaiser drags his victim to a different dimension with him and steals a portion of their stats. If he kills them, he keeps the stats until the victim respawns.
