Blood Art - 2nd Moon: Blood Puppet -> A skill that controls any being or thing having blood in them. Effective area: 5 meters.
Yes, that was the weakness of this skill. It could only be used if the opponent were to be in the range of the user. Of course, this was applied only at the beginning. After Luke consumed the entirety of the blood elixir, the effect area or range would soon then increase.
The range would still exist and this meant that he wasn't invincible since he couldn't stop attacks from a farther range.
For example, if a sniper were to shoot, he would most likely end up getting shot. Thus, he was;t invincible. But why should he reveal this to anyone?
The less the people know, the better and thus, he boasted his strength in front of Sam to make him feel miserable after tasting his powers.
"Luke, I think he has learned his lesson.", Isabelle said with a smile.
