Knife of the Unchained

Knife of the Unchained
"A thick, double-edged knife forged from masterfully forged electrum. A chain connects to the lower grip and ends in a bauble shaped in the form of a lantern. A jade glows in a shifting neon green light from inside the lantern. When the lantern is held to the ear and focused on, it sounds as if a dozen voices wail in the distance."


 * (Requires Attunement)


 * The knife is magical and considered a +1 weapon for attack and damage rolls.


 * The knife can be used to bind the user's soul to another creature.  The creature must be living and not Undead, Construct, or Plant. When a creature who is at half or lower health is hit by the knife, the user can, instead of doing damage, choose to instead bind his soul to it forcefully. The creature must make a charisma saving throw vs the User's Spell Save DC. If the attack is attempted before the enemy has half health, the binding automatically fails. On a fail, both the monster and user take 5d4+5 psychic damage and the user has disadvantage on his next attack roll.  This can be done once per week, on fail, the use is used and requires another week before it can be used again.


 * On Success, both the monster and user fall unconscious for 1d4 hours.  When they awaken, the user and monster now have the following traits:


 * 1) The creature is now non-hostile to the user and follows any command to the best of the ability that involves physical actions or labor. Deception and personal actions are unaffected and based entirely on the creature.
 * 2) The user gains a +1 to any one ability score the creature has at least a +1 bonus to. Once the ability score is chosen, it cannot be changed. The creature also gains a +1 themselves to any one ability score the user has a bonus to. Once the ability score is chosen, it cannot be changed.
 * 3) Whenever the user is damaged, 1/4th of the damage is applied to the summon instead of the user. Vice versa, whenever the creature takes damage, 1/4th of the damage is applied to the user.
 * 4) The user and creature retain a telepathic link over a distance of 500 miles. The user can understand the creature, vice versa, the creature can understand the user. The ability for speech is based on the intelligence scores of user and creature.
 * If the monster that is soul-bound dies, the user immediately falls unconscious and must make a DC 15 Constitution save. On fail, the user must begin to make death saving throws as their soul is torn between the planes of the dead and material plane. On success, the user is unconcious for 1d4 hours, but stable.


 * If the user is on a separate plane of existence than the bound creature for seven days in a row, the spell ends and the user and monster take 5d4+5 psychic damage and fall unconscious for 1d4 hours. The souls are torn through planar space instantly, as the soul-binding ends, to their respective bodies.
