Yeah, it´s amazing that Loki got lucky enough that Harald randomly came into his senses and became defenseless,while fighting Loki, and not when fighting Gaban, Shanks or any other character. He really is lucky, which is why at the end of the chapter, we saw Gaban talking about how amazed he was at Loki´s luck he unlocked, as well as Imu wondering what kind of luck exists on Elbaf.
