What are some useful strategies for construction?

[Ironhawk]

There are also a handful of good spells in the Construction path. Can't remember them offhand but I know that Mechanical Men (and whatever the more powerful version of that spell is) are both there. Thats a good spell, particularly in the hands of a powerful Earth mage. Is weapons of sharpness there too? Or legions of steel? Can't recall. Tho I think that Iron Dragons and Golems are at the top end and they are good summons.
