We were told that Roger Shanks or Reilly can charge anything with their axoc, and they don't need a sword, but the truth is that they have NEVER used acoc without a sword. Shanks can't hit Aramaki with his acoc even from a distance without pulling out his sword. In general, another proof that acoc + sword + fencing is a single whole. Zoro has spent 99% of the last two years studying haki. Tempering haki with mihouk,acoa (green smoke) acoc (black lightning). Well, the final hardening of the three haki blades. cry. Mihawk>Shanks
