Black Blood is a branch of Juinjutsu similar to Curse Seals that utilizes Nature energy and Yang chakra to give a physical form to a person's Id. Created by the Kurama clan during the Warring Clans Era, it was labled a kinjutsu due to those attempting to fuse their blood with their Id often going mad or the blood rejecting it's own body, killing the subject. However, those who survive the process with a sound mind find that their newfound power is worth the price, now known as Meisers.
The NPC 'Black Blood'
The Black Blood is treated an a Unique NPC that ranks up with the Meiser, with a few differences:
1➤The NPC's Stamina increases the Senjutsu Chakra pool instead of their own CP. See Black Blood Chakra Pool
for more info.
2➤The NPC does NOT gain any Skill points, cannot trade for Skill points, and can only use the skills/elements the Meiser already has, but it's stat raises go up to 24 as if it traded 4 skill points.
3➤The NPC has the same jutsu as the Meiser, and if it learns a jutsu, so does the Meiser (with 1 exception, see rule 7).
4➤If the NPC wants to use a jutsu, it draws from the Meiser's CP. The 2 exception to this are when the Meiser & Black Blood are in Resonance or if the NPC is using Chijutsu, then the NPC may pay in Senjutsu CP.
5➤The Meiser can use their XP to increase the NPC's stats, but not the other way around.
6➤If the NPC were to die, it instead enters an inert state for the rest of the thread, giving the Meiser debuff penalties and losing access to any Black Blood abilities for the rest of the thread.
7➤The NPC can get implants, but whatever implants the NPC gets are separate from the Meiser's Implants, and may have slightly different effects. The jutsu's learned this way are the exception to Rule 3 and limit the amount an NPC can learn following the NPC jutsu rules. Jutsu learned this way are not learned by the Meiser. See Black Blood Implants
for more info.
The Black Blood is also bound to the Meiser, so while it can take a vaguely human form, without techniques the Black Blood cannot reach farther then 5m away from the Meiser. Spilt blood within 100m can be recalled back to the Black Blood for 5 CP, the speed equal to it's speed stat.
By paying 500 XP, the Meiser learns how to enter Resonance. By using senjutsu chakra as a medium, both the Meiser and the Black Blood can increase their overall fighting capabilities. This is due to Chijutsu temporarily increasing the physical and mental bonds of the Meiser and Black Blood.
Meisers and Black Blood in Resonance get a (++) Tier unique boost to Strength, Constitution, Speed, Coordination, and Perception while Resonance is active. When the Meiser reaches S-Class (X-Class if the user started at B-Class), by paying 2,000 XP this boost can be increased to a +1 tier unique boost instead. If 2,000 XP has been invested into Living Weapon ability, instead of providing an boost the Black Blood can choose to temporarily replace some or all of the Meiser's stats with their own and vice versa. Stats that are not temporarily replaced still get the (++).
The Black Blood is able to harden, soften, and alter it's shape, allowing it to turn into various living items. This naturally allows it to defend the user from most attacks as it hardens inside the user's major blood vessels to defend against attacks. By paying 100 XP, blood can take the form of 1 weapon, armor, , simple item or extra body part of the user's choosing, though the Black Blood gets a free chibi body with head & arms to start so it can communicate. This can be done multiple times, with each investment giving the Black blood a new form that it can swap to. Outside of techniques, the maximum amount of items that can be formed at a time is limited to 1 per Class, maxing at 6 at X-rank, though the amount of shapes the blood can take are theoretically infinite. Items made in this form have a Hardness equal to the Black Blood's current Constitution, while it's Rank it equal to it's current Strength.
Black Blood Enhancement
By mixing the Meiser's chakra with the Black Blood's Senjutsu chakra, Meiser's can enhance the power and effectiveness of that technique. This can create techniques referred to as Chijutsu; AKA Blood Arts. Chijutsu is easily mistaken for Jujutsu, but is in fact a separate branch. The user can also simply improve the power rank of a regular jutsu by 1 using this. To do this, the Meiser need only spend half of the technique's cost with the Black Blood's CP, while using their normal chakra pool for the other half. Chijutsu & the powered-up techs are often the color of the user's blood, though this is an aesthetic change.
Black Blood Implants
As the Black Blood is it's own being, it can receive implants like any other living thing and adapt to it's new makeup. As the implant is put in the Black Blood and not the Meiser, no custom techniques can be made without using Black Blood Enhancement
and instead take up the normal NPC jutsu slots. However, while the passives stat bonuses are transferred to the Black Blood, the abilities the Black Blood gains can alter how it affects the Meiser. The KKGs that interact slightly differently due to it's Fuinjutsu makeup, listed below.
➤Kaguya - Meiser's bones become black. Increases inert debuff by (-)
➤Nature Clan - Increased passive Senjutsu CP regen by 5.
➤Any Dojutsu - Cannot be implanted
➤Kurama Clan - Cannot be implanted
➤Uzumaki & Senju - Takes up both a Black Blood and Meiser Implant Slot, requiring 2 rolls to implant, the lower roll being taken.
Finally, due to the blood being naturally adaptable, the Meiser can pay 100 XP to increase a single implant roll by 1 for either themselves or the Black Blood. This can be done multiple times, but must be done before each roll, though the drawback of this is that neither the Meiser or Black Blood can make use of the additional modifiers outside of their Base Stats listed in the implantation rules anymore as the Blood has permanently altered their DNA.
Black Blood Chakra Pool
As the Black Blood is a living seal that stores Senjutsu chakra, it has it's own pool of Chakra. As such it's own chakra pool is increased by increasing the Black Blood's Stamina stat. At the start of each thread, it's SP is topped off like the user's. When Resonance and/or Living Weapon are not in use, the Black Blood regains 5 points per post. There are also 2 additional ways to supplement SP.
➤If the Meiser has been trained in how to gather nature chakra, staying still allowing them to gather an additional 5 points per post. This also applies to their clones as well as sage summons.
➤By implanting the Nature Clan Bloodline into either the Black Blood, The Black Blood is able to passively generate 5 points of Senjutsu Chakra per post, regardless of what they're doing. Implanting Nature Clan bloodline into a Meiser won't increase this generation.
While in Resonance, Meisers use a constant draw of Senjutsu Chakra from the Black Blood. This begins at the cost of 20 points per post, but by spending 500 Experience Points, Meisers can halve that value to 10 points per post. If the Meiser has Kekkei Genkai Ressha from the Kurama bloodline, spending another 500 Exp Points to bring the cost down to 5 points per post.
The Black Blood is still it's own being, and as such can still be affected by mental effects separately. As such, while a Meiser can use Genjutsu Kai on the Black Blood and vice versa, as long as the Black Blood is caught in a genjutsu that doesn't allow movement, their abilities cannot be used. In addition, while the Meiser may be able to use the NPC's Constitution to defend against certain attacks, such as blades and hammers, this doesn't protect them from threats such as fireballs or Kumo's Heavenly Transfer Technique as the NPC is located in the Meiser's major blood vessels. This make opponents such as the Chinnoke and Hyuga extremely dangerous, as they each have ways to bypass the Black Blood. Blood thinning and anticoagulants are also an issue, both causing a (-) debuff to the Black Blood's Strength and Constitution for each rank of the chemical, separate from the chemical's other debuffs.
If Black Blood is 'killed', it enters an inert state and cannot be used for the rest of the thread and Meiser takes a (--) to Strength, Speed, Coordination, and Perception. The only way to truly kill the Black Blood is to kill the Meiser, as their body now naturally produces the Black Blood.
Boosts from the Nature Clan, Cursed Seals, and Sage Mode do not stack with Black Blood.
