Actually, I was just thinking, I can still use this spell on them. Because, if my memory serves me right, it should also drain the enemy's magical energy. And I hope these golems don't have infinite mana.

Even more interestingly: since the golems move not due to "life force," but magical energy (which this spell consumes), the spell may have unforeseen side effects on them.
