Spirit Spear Chastiefol

 * Pillow: When not in battle, the spear remains in the form of a pillow. The pillow can also act as a shield.
 * King frequently utilizes this form, which is a long, broad spear, in conjunction with his levitation ability to perform basic ranged attacks. It acts as a homing-weapon, continuously following a dodging enemy and cornering them.
 * By controlling Chastiefol with his ability to levitate objects, King launches a multitude of attacks which rapidly swarm the enemy in all directions.
 * Chastiefol takes on the form of a large, stuffed bear by shape-shifting the moss that grows along its body. While in this form the moss body will parry any physical attack, but can also be directly controlled by King to fight or immobilize enemies with its four arms. Due to the high water concentration within the moss it is highly resistant to fire; however, because of this quality it bears a weakness against cold and freezing attacks. Additionally, the form's soft, fluffy body allows it to resist blunt force attacks.
 * This form of Chastiefol is a twin headed spear with a spearhead shaped like the claws of a crab. This form has the ability to petrify an individual whom it pierces, rendering them unmovable and immobilized as a statue even if they are still alive.
 * A gigantic shoot emerges from the earth, towering over enemies, as a flower bud blooms and shoots several projectiles that are capable of a great amount of destruction.
 * An army of small kunai-like spears are multiplied from one, their individual trajectories are controlled by King at will through simple motioning and gesturing of his hands.
 * A subsidiary technique of Increase, it focuses all of the small blades that comprise Chastiefol into a single downwards strike against an opponent.
 * Chastiefol transforms into a luminescent, ringed sphere that illuminates the surrounding area. It acts as a torch that allows the user to easily see in dark places.
 * A large barrier is formed around a person and is capable of withstanding even the most powerful attacks. The barrier is made of pollen from the Sacred Tree which have the capabilities of slowly healing and subsides the pain immediately.

Combined Techniques

 * A combined attack, in which while Diane throws a rock barricade the opponent, King attacks piercing his body with Chastiefol.

True Spirit Spear Chastiefol
The is the complete form of Chastiefol achieved only when King draws out the true power of the Sacred Tree. It is activated with the command, after which King's body is flooded with magic from the Sacred Tree. The magical burden it puts on King is so great that his body cannot physically sustain the immense power and he is left exhausted and wounded. Releasing Chastiefol is also shown to cause King's power level to momentarily double that of an Albion. After obtaining his wings, King became able to accede to the true power of Chastiefol without any repercussion in his body.
 * The true first form of Chastiefol takes on the appearance of a great spear that dwarfs King in size. King utilizes this form by launching the spear at his opponent; creating an enormous, cross-shaped explosion upon contact.
 * In its true second form, Chastiefol appears as a muscular stuffed bear. Its strength and destructive capabilities are dramatically increased.
 * In its fifth form, Chastiefol appears as an army of large kunai-like spears.
