Lore
A mutated Thief Bug monster corrupted by the dark energy in the sewers. Its attack and agility are far greater than a normal Thief Bug. It is the enemy of Male Thief Bugs—another type of Mutant Thief Bug—and they dwell in different areas of the sewers. A friendly reminder from the Kingdom Defense Force: Mutant Thief Bugs have been running rampant recently. Adventurers, please be careful if you run into Mutant Thief Bugs.
