Moments earlier, Ed was stuck fighting against Samuel without being able to get an upper hand. With his current attributes, Ed was capable of keeping up with Samuel but… His swordsmanship was still too swift.
He was also trying to conserve the crystals he carried as they weren't unlimited. He planned to use them on the mass of adventurers. This had led to a very precarious situation.
'That blade is simply too sharp' Ed complained inside his mind.
Samuel's speed put him at a disadvantage in close quarters but if it was only that he was confident in eventually gaining the upper hand. Humans were bound to make mistakes when pressured for a large period. The problem was the sword he used which easily sliced apart anything he conjured.
Even his reinforced body was not enough to withstand it so he could only stay on the passive side.
