Timothy had armed everyone with weapons and armor made out of artificial bones. Although the artificial stamp may make them look less dependable, that was not actually the case, because he had designed them to be harder than any normal bone itself, by densifying the material that he worked with. The weapons and armor were just as good as real weapons, though, a bit weaker than actual ironware.
The goblin slaves carried swords, as he didn’t care to take their special requests. As for Timothy’s friends, they all had a weapon of their own choosing.
Timothy had a large claymore, fit for a Fal Goblin. It was a meter long, double edged, and designed to be quite sharp! He was barely experienced with swords, so he was hoping to not cut himself accidentally if a battle broke out, but he felt comfortable with his choice. He figured that bigger swords could help him take down bigger monsters.
