|Gold requirement for unit recruitment decreases by 2% per level.|
This is a passive spell that is always on once it is researched.
Behemoths require that this skill be at level 9 anyway, but level 10 is another story. Level 10 requires 225k worth of resources for a 2% decrease in production costs. Assuming that Behemoths are the only unit in production, Manufacturing level 10 will reduce costs by 22 gold per Behemoth. Dividing 225k by 22 we see that one would have to produce more than 10,000 Behemoths to recoup an investment in level 10 Manufacturing Skill. In short, don't do it.
