I need to make a wizard for a single player campaign, for which I have found a PrC* that will allow me to lower the creation cost of one specific type of magic item, such as a wand of magic missile, rings of protection ect., by 30%, and I want to use this massive discount to craft myself an army of BSF constructs. But which ones? I need to choose one specific kind that will serve me well from 10th on, and scale well enough in power to continue to be able to tank near-epic opponents.
I like stone golems, but they become available a little late for my taste, so I need your help. What is the best construct you know of? All official WotC non-campaign specific books are allowed, as well as all books specific to the DragonLance setting. Bonus points will be scored if the construct in question can be constructed from level 6 and on, as that will allow me to have it from the beginning of the game.
