When the clone rushed down the snowy mountain and set foot on the meadow at the foot of the mountain, Sheyan suddenly shook and split in two. This was the effect of the 'Rank 6 copying scroll (marked)' given by Franklin.
[Tear this scroll and use it on a target to produce an illusion of the target. The illusion will have 100% of the target's HP and 30% of the target's attack power]
The illusion could not use any abilities or items but looked exactly like Sheyan.
The clone looked distracted for a moment. He seemed to be looking for something in his personal space. After that, he too divided into two, obviously using the scroll as well, keeping up with the man-to-man coverage. For the clone who had temporarily lost his logical thinking, imitating Sheyan's behaviour was undoubtedly the safest thing to do.
