The characters' ability to sense energy and magic over long distances in this series seems to lack any sense or coherence, several situations where extremely strong and magic proficient characters can't sense magic from a distance while much weaker and inexperienced characters can do so is a recurring thing. in this series, it doesn't seem to have any logic or sense to it. As when the 10 commandments awakened, absolutely no one other than Meliodas felt the awakening, Merlin only knew of the awakening of the 10 commandments after being informed by Meliodas, how can this be possible? All other Sins are extremely strong and should also have felt a powerful evil energy awakening, even Meliodas when he was only a power level of 3000 was able to feel Gilthunder's magic approaching, if Meliodas was able to feel the magic. from the 10 commandments to hundreds or thousands of kms so it should be simple to track anyone just by feeling their traces of magic from very far away, but instead all the characters are looking for information and need it to locate their companions, None of the sins was able to of feeling Zeldris even being close to them, no one felt the strong energy of the 10 commandments from a distance, while everyone felt the 4 commandments of Mael from a distance, how does that make sense?. Even Donny Nasiens and Anne were able to sense Pellegarde's magic from a distance, you could argue they are very talented, but now even Hendrickson who has an ordinary power level was able to sense the return of the 10 commandments. This simply seems like a feature entirely made to impact the plot, lacking any logic or sense when it really should be needed.
