You are correct, I cannot fault your quotation.

However under Energy Cost, Page 8 "Never reduce the cost of a Blocking spell;" While this is in reference to Energy reduction for high skill, it may apply to Blocking Spells with the Power enchantment as well.

Boost is inherently a single roll and a blocking spell. Despite the description under Power, I would personally rule that either the Power Enchantment didn't apply, or more likely, that you could use it, but only when discretely activated. Clearly the mechanism for an always on stat boosting item is meant to use the spells that are the prerequisite for a given boost.

But by the RAW, I suppose you are right.
