then you have a poor rune/mastery setup or you tried clearing too many camps.
im talking early invade
start with hunters tali
golems + red = level 2 and change, smite both of them, finish with 2/3rds your health + a potion to use.
AD reds, armor yellows, CDR blues (flat 5%, and 5% at level 18)
quints 1 armor, 1 ad, 1 ms. i recommend ms over armor and ad if you have to choose.
wukong has mastery options, moreso than others. i prefer 0/18/12, take 45% cdr, and buff extension(or assassin) right side is again, your preferences, but nothing besides 2dmg reduction is going to help much, but i take the bonus 5% armor/mr because i dont build full ad.
your other option is 12/0/18, taking strength of ages, which is also good.
get a solid leash at golems, clear red and smite it and invade him. its soooo easy, i have no idea why you finish so low, maybe you aren't canceling jungle auto attacks and getting 2 autos blocked when you use W. auto -> E -> auto -> monster raises arm, W make sure clone is closer to minion, he ends up canceling 2 autos). also kill the lil ones first. finish and find khazix at wolves or raptors and hes donzo.
