He looked at his identical-looking phantom walking towards him with apparent wariness and noticed the only difference between them. The swords, to be more precise, not exactly the sword in itself but the engraving on it, pseudo runes on both of the swords, his and his replica were the same, but there was also a profound difference.
He could spot it with his runic eyes. Alternating his gaze between that rune engraved sword and his own, he could pinpoint the core differences and how much lacking his own rune engravement was, but before he could analyze the situation any further on his part, his rune phantom had already reached quite close, it abruptly swiftly rushed towards him and made a gesture of attack.
