Looking at the number of wooden balls in front of him, Eisen let his mana infuse the enchantments of two of them. They both rolled forward at the exact same speed, at least according to the speed measurement device that he improvised.
It was a simple item that looked at a specific area and could lock onto determined objects, measuring exactly how fast they moved, saving the specific speed at certain intervals. On top of that, it could measure the time it took for an object to reach a specific line; Eisen made this item specifically for this test. And from what he could see, the two balls were moving almost exactly the same speed.
One of them was a wooden ball made from regular oak, and another was made from a dead oak treant's wood. The one made from the treant's oak reached the 'destination' fractionally faster, but the top speed between the two objects seemed identical. The only difference was that the treant oak ball accelerated a tiny bit faster.
