Riftmaker and Liandry's Torment build damage and sustain while Darkness Rise keeps Mordekaiser in extended combat. Hextech Rocketbelt is the build's only active item and helps him find range for Death's Grasp or Obliterate, while Rabadon's Deathcap greatly amplifies his AP ratios. Amaranth's Twinguard and Armored Advance supply defenses after he isolates a target in the Death Realm. In the combo simulation, chaining abilities and attacks builds Conqueror quickly and gives the best extended-fight value.
