#How to make Wukong hit his 50% winrate with one simple fix:
#W - DECOY
ACTIVE: Wukong blinks 100 units away, enters invisibility for 1.5 seconds and leaves behind a decoy of himself.
After 1.5 seconds, the decoy performs a circular attack around him for 0.5 seconds, dealing magic damage to all nearby enemies, and then vanishes.
MAGIC DAMAGE: 70 / 115 / 160 / 205 / 250 (+ 60% AP)
COOLDOWN: 18 / 16 / 14 / 12 / 10
#NEW
ACTIVE: Wukong blinks 150 units away, enters invisibility for 2 seconds and leaves behind a decoy of himself, which will proceed to perform wukong's last command.
Wukong's clone attacks any nearby champion for 20% of wukong's AD. After 2 seconds, the decoy performs a circular attack around him for 0.5 seconds, dealing physical damage to all nearby enemies, and then vanishes.
PHYSICAL DAMAGE: 25 / 50 / 75 / 100 / 125 (+ 50% AD)
COOLDOWN: 14 / 13 / 12 / 11 / 10
