How to play as Wukong
Look for a short trade only after Mordekaiser misses Obliterate(Q) or Death's Grasp(E); Wukong players recommend waiting for one of those cooldowns before dashing in.
Do not extend an even trade once Darkness Rise(P) is active. If Mordekaiser has the aura running, disengage and return to farming instead of letting him keep hitting you.
Mordekaiser's Darkness Rise(P) activates after three attacks or spells; Wukong's Decoy(W) leaves an attacking clone that can give Mordekaiser another nearby target while he builds or maintains the aura. (Unverified: no source confirms this note.)
