How to wukong jungle.
Rule #1 - you are not a tank. You are an assassin mid game and bruiser late game.
Rule #2 - never start blue/red
Rule #3 - always get decoy level 2
Rule #4 - use your decoy to tank jungle damage
Masteries/Runes - use typical offensive top lane runes, except I would recommend some armor pen runes as well. 12/18/0
1st clear (no gank)
Level 1: Start E (Nimbus strike) and toad/krugs - smite immediately. Skill order: AA, E/smite
Level 2: Take 1 point in W (decoy). Ward blue/red bush, move to the next small camp (wolves/wraiths). Kill the small one first. Skill order: AA, E, W
Level 2.5: Move to next small camp on other side of the jungle. Repeat above, use smite (or save for last small camp).
Level 3: Take 1 point in Q (crushing blow). Move to last small camp. Skill order: AA, Q, AA, E, W
At this point, you can decide whether to take crab, you would have fairly low hp
If you end up on red side with smite, you can take red - but i wouldn't recommend since you'll be wasting the buff going back and buying.
2nd clear
Step 1: go back to your first small camp (save smite for blue/red).
Step 2: take blue/red
Step 3: take second small camp (option skip depending how soon you want to gank)
Step 4: take red/blue
Step 5: gank (or continue farming small camps)
