Basquias has ten forms, but is most commonly seen in the form of green octopus-like limbs wrapping around the user's body. It currently shows signs of black coloring at its tips, symbolizing the demonic corruption of the holy weapon of the Fairy Clan.
In its authentic form, it is a spear of immense size, as much as Chastiefol in its true form. This after the blade has a half circle.
