The Kikoku is an unbreakable sword that carries 2 points of the Soul Rending attribute while held in the main hand.
When an attacker with Soul Rending damages a living target, the target temporarily loses maximum health equal to the attacker's Soul Rending value. With an unmodified Kikoku, each successful application removes 2 maximum health, or one heart. Sculk Soul particles appear around the victim when this happens.
Soul Rending can apply at most once per second to the same target, even if it is attacked more quickly. Repeated applications stack, and a target whose maximum health is reduced to zero is killed.
The reduction is not permanent. Afterward, the target recovers 1 maximum health every 3 seconds until all of the health removed by Soul Rending has returned. Soul Rending changes maximum health rather than dealing additional ordinary damage, so healing alone cannot restore the unavailable hearts while the effect remains.
Soul Rending is an entity attribute rather than behavior exclusive to the Kikoku. Other mods or datapacks may grant a different amount of it to equipment or entities.
The Kikoku also gives its wielder an additional chance to obtain Soul Fragments from defeated entities.
The Kikoku supports Infinite Enchantment Stacking.
