Green Sun Heart (Item for Loshi Plot)

This item is for Loshi's upcoming plot, where someone is injured in a hollow fight (sorta) and needs a new heart. Reathin's going to build one and implant it (with help from 4th), which will kick off the plot.



Name: Green Sun Heart
Type: Item - Standard
Tier: VI
Condition: N/A (Internal Implant)
Description: When unimplanted, the Green Sun Heart is a prosthetic heart composed of a number of alloys, predominantly spiritually enhanced platinum and powered by a connection to the Soul Sleep and Chain Link. The device needs a trivial amount of energy to maintain the function of a conventional heart. It's other, more advanced abilities, require greater infusions of reiryoku. When in active use, the power of the heart partially taints its wielder's bloodstream with a bright energy the color of verdigris (hence the title "Green Sun" Heart). Passive aspects do not trigger this visual effect.

Name: Green Sun Surge
Class: Item
Tier: VI
Type: Supplementary
Range: Self
Description: The Green Sun Heart is more than a simple pacemaker. It pushes its host's physical power beyond normal limits, booming audibly as it does so. This provides a boost to either Strength or Speed (only one at a time) for five post cycles, granting a x3 boost. The unnatural power of the heart puts serious strain on the user's circulatory system, however. Using it once a thread is tolerable, but tiring. Using it a second time will inflict tier III damage on the user as their system tears itself apart to keep up. Used a third time in a single thread increases this to a full tier VI of self damage. The system will forcibly shut down if attempted a fourth time, essentially giving the user a momentary heart attack before resetting into basic functionality (preventing the Heart's first three powers from activating for the rest of the thread, but still pumping blood and all that).

Name: Emerald Arsenal
Class: Item
Tier: III-VI
Type: Offensive
Range: Short
Description: In an attempt to ensure that his patient is not without weaponry in the future (hopefully preventing further extensive surgery), Reathin has designed the Heart to ensure the host is never truly unarmed. It sends reiryoku through the bloodstream, which exits at the pours and solidifies on contact with air into solid-energy constructs. These always take the form of a personal-scale weapon (melee weapons are simple, ranged weapons manifest a steady stream of ammo at the cost of a bit more reiryoku every shot). The weapons are short lived, only managing 4 post cycles at best, but the more energy is infused, the more powerful they are.

Name: Alternate Configuration
Class: Item
Tier: I
Type: Passive
Range: Self
Description: Originally, this feature was designed to allow the heart to reconfigure itself so that, if the target was ever grievously injured, the implant would still be able to get blood where it needed to go. It does this, however by tying it into the Soul Sleep and Chain Link, a greater effect occurred: the host may reconfigure their external body to a mild degree. These changes aren't boosts, defensive or offensive, healing, or anything with a direct advantage in combat, but does allow the user to reform their outer image extensively, provided they don't change size and keep the same general layout (head, limbs, etc.). Skin tone, voice, hair color and style, visible gender traits and even the unique aspect of his reiatsu (not the size or type, just he specific signature. He couldn't change it from shinigami to arrancar, but he could feel like a different shinigami of similar strength) can be altered, making it extremely good for disguises. The changes are real and last until changed again, but are of limited use outside infiltration.

Name: Heart of Metal
Class: Supplementary
Tier: I
Type: Passive
Range: Self
Description: This "ability" was not an intentional aspect of the design, instead representing an unforeseen interaction with the surgical subject's hollow corruption and the heart's internal energies. In essence, it poisons the soul of the one it is implanted in, doing extreme damage to their sense of empathy. Anyone with this "technique" functionally looses their ability to perceive people as people, rather than tools to be manipulated. The user can perfectly fake such emotions, but beneath all that, they can truly care only for themselves. Sadly, as long as the Green Sun Heart exists within their chest, the effect constantly reinforces itself, making it impossible to regain their empathy without its removal and a great deal of practice reconnecting with people.
