As soon as the preliminaries ended the real tournament started, I was surprised at how fast the preliminaries were, Borges had no mercy in eliminating almost all the participants and not even saying how they got it wrong.
Everyone was watching but didn't understand a thing about analyzing a weapon or analyzing metal.
Diana said something about being able to analyze how someone fights by seeing the sword that person uses, I imagine a Blacksmith should do a similar but deeper analysis.
When the real tournament started we could see all the Blacksmiths working, thanks to my senses I was able to perceive a lot more things than the others in the audience, I'm sure it would be the same for my companions.
