Thing is 魔力 is rally a neutral term, while 精 and 魔物の魔力 are two states/aspect of it. By calling 精 and 魔力 with exactly same word, it imply that 精 is 魔力 in it neutral form as well, while 魔物の魔力 is altered/odd/alienated.

Now I agree that there's simply no English word that cover as much as 精 (spirit, essence...and semen), I still think that whatever the term to use, it's better different from 魔力.
