Husk Warrior

"The remains of a bug, animated by a strange force. Wields a nail and shell. Softened by generations of luxury, these bugs lack claws or armour or venom. Those who wish to protect themselves are forced to fashion weapons from stone, ore or shell."

Husk Warriors are enemies in Hollow Knight. Unlike most other husks of their size, these reanimated corpses use a nail and shell when fighting.

Behaviour and Tactics
Patrols back and forth. Once disturbed, it defends with its shield, even if the Knight attempts to perform a down-strike. When it attacks, it performs three consecutive strikes before defending with its shield again.

The fastest way to kill it is to attack it from the front so it blocks the attack and begins its attack sequence. Then, while it is attacking, jump and attack it from above. The Knight can also down-strike repeatedly until it is dead.

Location
Only two can be found in the Forgotten Crossroads, to the east of the Stag Station.

Trivia

 * In a Kickstarter update, it was referred to as "Endemons Sapien (Infected)":
 * "These vicious, mindless ghouls were once ordinary bugs like you and me. Something below the surface has burnt away their souls and filled them with an aimless rage."
