Notes:
This katana has a very interesting history. It was originally accidentally released in Release 11 along with the Lair of Draconis as a drop from the original black dragon named Thanatos. However, in a duping hotfix, it was transformed into the Useless Katana.
When the Lair of Draconis was officially released in Release 22, the weapon was altered considerably and renamed to Annoying Firecracker Katana, and dropped from the new version of the black dragon named Feargus. The AFK katana was considered a heavy nerf from the Celestial Blade because of its short effective range and shorter true range, lack of piercing, and the fact that it only barely outdamaged the Doku No Ken until about 5 defense.
In Build X10.3, the AFK was changed to its current form, the Sullen Blade, which has a much higher damage output and a longer effective range, making it much more viable, if not more practical.
