Mordekaiser Abilities Overview In League of Legends

Mordekaiser’s kit is built around overwhelming his enemies with sustained magic damage and controlling fights with his powerful ultimate. His passive, Darkness Rise, deals bonus magic damage around him after landing three attacks or abilities, making him a strong skirmisher. Q – Obliterate is a smashing blow that deals heavy damage, especially when it hits only one target. W – Indestructible stores damage taken and dealt, which can be used as a shield or converted into healing, giving him excellent durability. E – Death’s Grasp pulls enemies toward him and shreds their magic resist, helping him stick to targets and burst them down. His ultimate, R – Realm of Death, isolates one enemy champion in a shadow realm for several seconds, allowing Mordekaiser to eliminate high-priority threats before they can impact teamfights.

Best Build For Mordekaiser

The best build for Mordekaiser in League of Legends focuses on making him a durable AP bruiser who can sustain through fights and deal consistent magic damage. Start with Riftmaker for omnivamp and true damage scaling in long fights, followed by Rylai’s Crystal Scepter to slow enemies and keep them locked in your damage zone. Add Demonic Embrace to increase your damage over time and give bonus durability. For boots, go with Plated Steelcaps or Mercury’s Treads depending on the enemy comp. Round out the build with Zhonya’s Hourglass for survivability and Spirit Visage or Thornmail depending on whether you need more healing or anti-heal against enemy lifesteal champs.

Best Combos To Learn For Mordekaiser

To maximize Mordekaiser’s damage, start with a basic Q > Auto Attack combo to poke in lane. For an all-in, use E > Q > Auto > W, which pulls enemies in, deals a burst of damage, and heals you. If you’re going for a kill, especially post-6, use E > R > Q > Auto > W to trap your target in the Death Realm and burst them down while sustaining through trades. Always try to land your Q when enemies are isolated for maximum damage, and use your W wisely—either as a shield when you’re about to take heavy damage or to heal when you’re low. Keep up your passive by staying in fights and weaving autos between abilities.
