Mordekaiser's Passive & Dodges

Morde's passive, according to the wiki and riot site are: Damaging abilities or basic attacks grant 1 stack per enemy champion or large monster hit, up to a maximum of 3. At 3 stacks, Mordekaiser gains Darkness Rise for 4 seconds. Further basic attacks and abilities against enemy champions and large monsters refresh the duration. DARKNESS RISE Mordekaiser gains a powerful damage aura and movement speed after landing 3 attacks or spells against champions. However it stills procs even if the auto attack is dodged.
