The Shattered Blade Butterfly was an extremely basic Butterfly Guardian Beast. Although this Gold Attribute Guardian Beast was indeed valiant in battle, capable of inflicting considerable group damage with its Unsheathing Skill, its nature as a melee unit made its wings extremely vulnerable to damage.
Once its wings were damaged, it wasn't as severe as a severed limb on other Guardian Beasts—an injury to the Origin that is difficult to heal—but it still required several months of recovery. If the wing damage was severe, it wasn't unheard of for recovery to take a year or two.
During this period, although the Shattered Blade Butterfly could still fight, its combat performance and strength were greatly diminished.
The Blade Butterfly had the same problem. To put it bluntly, the Blade Butterfly was just an extremely enhanced version of the Shattered Blade Butterfly.
