How to obtain:
While fighting throughout the game, there is a possibility a player will receive a 'Wolflobe' sword as a drop or charm from battle.
The Wolflobe Sword is the first four sword names combined. At times, the game will glitch and will give the character a charm or drop of 00, which isn't assigned to any single weapon. The first four will thus result; Wood Sword, Iron Sword, Lode Sword, Red Katana.
Wolflobe is derived from a number of unreadable characters that partly spell the word; this weapon is a glitch, and does not actually exist.
