For blade, I was thinking of getting 1200 gold steel shaped blade (14 - 70 HP) and enchanting it with something. Maybe fire. BUt I'm not sure just how valuable the extra strength and dex from the Empathy Blade for creations is. Maybe I should just keep using it, stand back during the big fight, and use magic to support the creations like you said.
To check leadership, I went back to he beginning of the Stoneworks and made sure i put one more point into leadership. I was able to obtain the unfinished golems, but the self destructed pretty quickly. I guess that is because of my lack of leadership? The message didn't indicate that. It just said they were "old" or something.
