How to Complete The Finest Blade

The objective is to defeat the Bladebiter, which is a red Toughskin. This Toughskin can use Munch, which can destroy the targeted unit's weapon, shield, or armor. This can be a problem if a unit is equipped with anything rare.

The Toughskin can also use Resonate, which inflicts Disable on all units that are not equipped with a ranged weapon.
