Oh, no no. There are 3 core items, 2 options for the support item and 1 Wardstone.
That leave 3 core + 1 boots + 1 support + 1 wardstone = 6 items.

Then you have the situational items to substitute either for the wardstone, support item or boots.
You can't build both support items, I just put both because I also put both as options in the starter item in first purchases.
