So I played voodoo three times just to try him out, I think one was 16-9 10-4 and 7-2. Better than normal for me, but I want to optimize my ability with him.
Here is my Build Order:
Start:
x6 runes
x1 mana
x1 hp pot
x2 minor totems
Next:
courier/winged
bottle
Next:
Steamboots
Next:
Staff of the masters
Next: Shrunken Head

There's a big leap from items, I want to be able to be better at voodoo, what items should I get in between. And somehow I am always carrying my team, Is that normal?
