魔鬥凱薩+死亡循環S+Circle of Death deals 70% of heal as damage. Protein Shake amps shield/heal — Morde's W shield's heal-when-broken scales, dealing damage. Late, one W full-heal deletes squishies; W grants gray HP based on damage dealt, so with Executioner you can spam W forever. Never build Rift Maker or any omnivamp item — they override CoD damage. CoD deals magic damage — build magic pen. Enemy Serpent's Fang chunks your shield and damage.
