Kingsmould

An enemy found in the White Palace. This guard construct protects the King and the White Palace, wielding a curved claw-blade.

Tactics
These enemies have two attacks, a boomerang-like throw of their claw blade which can do damage as it returns, and a standard melee attack. They deal two damage with every attack, making them one of the most dangerous enemies in the game, but are thankfully fairly easy to take down. They are considered minibosses and do not respawn upon death.

Trivia

 * Although they seem to be made in the same way as the Wingmould, they do not regenerate upon being destroyed.
 * The corpse of a Kingsmould can be struck with the Dream Nail to access the dream version of the White Palace. This implies that despite being "constructs", Kingsmoulds do have a consciousness.
 * Their mind is apparently highly protected, as the Dream Nail cannot access it until being fully Awakened.
 * Given their inky black amorphous body, they might be created using the Void, similarly to the Vessels.
