Eisen was trying to figure out ways to properly implement his ideas into such a camera bat as he had planned. But since he didn't want to just do experiment on the actual crystal eyes, as they didn't have many of them, he was testing out enchantments on a regular mana crystal while gathering ideas together with Komer.
It seemed like the item that Eisen came up with was actually something that appeared in fiction every once in a while, so he was actually incredibly helpful when it came to such ideas.
