The Sharingan is the most feared ability of the Uchiha Clan. This unique ability manifests in a clan member's eyes, and while some might call it a genetic aberration or deformity, the Uchiha have used this gift to devastating effect. In some members this ability will only let them anticipate or predict the path of an attack.
Other clan members even have the ability to disorient and mimic an opponent's techniques, and although this aspect isn't perfect the Uchiha still have put it to good use.
A subset ability of the mimicry ability is that of the ability to copy and learn a technique that one's opponent has used, and there are members of the clan that have grown most powerful because of this unique talent. The most secret abilities of the Sharingan are also the most feared, and have not been able to be recorded by those outside the clan for no one has survived an encounter with these abilities unscathed.
To qualify to gain Sharingan Eye bloodline levels, a character must fulfill all the following criteria.
Minor: Intermediate:
Skills: Intimidate & Perception 4 ranks. Skills: Intimidate 8 ranks & Perception 8 ranks.
Feats: Advanced Bloodline (Sharingan Eye). Feats: Advanced Bloodline (Sharingan Eye).
TABLE: SHARINGAN EYE BLOODLINE TRAITS
Sharingan Eye (Su):
The character activates this ability as an attack action that does not provoke an attack of opportunity. He gains an insight bonus to Defense, Initiative and Perception checks and Genjutsu checks to detect illusions, as well as checks made to read lips or memorize a string of numbers, words or certain details (such as a crime scene).The character can concentrate for a move-equivalent action to gain the ability to See Chakra for as long as he concentrates, plus 5 rounds. Concentrating this way is the same as if he were concentrating on a spell or technique. The sharingan eye costs 6 points of chakra per round to maintain. If the character is blinded, he gains none of the benefits of the sharingan. Unless caught flat-footed, immobilized or feinted against, the character cannot lose his Dexterity bonus to defense while the sharingan is active. Deactivating this ability is a free action.
Special: Regardless of the level of the character, the sharingan can only be activated for the first time when the character survives an attack that would have otherwise killed him (succeeding a save, for example) and remains conscious.
High Speed Sight (Su):
When the sharingan eye is active, the character gains a high speed sight of the specified amount for as long as he can See Chakra.
Offensive Foresight (Su):
The character gains an insight bonus to attack rolls and Reflex saves, and Intimidate checks when his sharingan eye is active.
Glare (Su):
The character's sharingan eye evolves, and gains a third tomoe (a "comma"). The character gains a +4 bonus to perform Doujutsu techniques and detecting while his sharingan eye is active. The DC of the character's Doujutsu techniques increases by 1 while his sharingan eye is active.
Sharingan Technique Mimicry (Su):
This ability allows the character to copy techniques using the Sharingan's precognitive ability, and its ability to see chakra. In addition, he gains a bonus to checks made to remember things he has seen with his Sharingan Eye active equal to his Sharingan Eye bonus. The character readies an action. Any technique he sees performed within 50 feet, he may copy using his readied action. The character must must meet the requirements of the technique to copy it, and if he does not, the readied action is wasted. The technique must be a Genjutsu or Ninjutsu technique performed with hand seals or half seals components, or be a Strike or Stance subtype taijutsu technique. A Chakra Control technique, a technique performed with no hand seals or an Enhancement Taijutsu technique cannot be copied.
To copy a technique, he must succeed a check to identify it and check again to Perform the technique. If both checks to identify and perform the technique, the maneuver can be initiated. When initiating the maneuver, the character has a 80% base chance of success. If he fails, the readied action is wasted, but he spends no chakra. If he succeeds, the character must pay the same chakra cost as the technique that was performed (accounting for metachakra feats and the technique being empowered).
If a meta-chakra feat was applied to the technique, the chance of success is reduced by 30%. The character is able to determine if a meta-chakra feat was applied to the technique when he succeeds on identifying it. If the victim is under the "Technique Copy" effect of the Sharingan Ougi - Shinkou Jutsu technique, the chance of success increases by 10%. If the character can See Chakra, the chance of success increases by 10%. If the maneuver succeeds, the character can choose to Copy, Memorize or Nullify.
Copy:
The character performs the technique as it was performed by the creature he copied from, and it has the same effects. The character gains a +2 bonus to Learn checks made to develop the technique for 2 weeks. If unused, the bonus fades.
Memorize:
The character gains a +4 bonus to Learn checks to develop the technique for 1 month. If unused, the bonus fades. He regains one-half the chakra cost he paid to initiate the maneuver.
Nullify (Genjutsu or Ninjutsu only): The character counters the creature performing the technique, and the technique has no effect. The character gains a +2 bonus to Learn checks made to develop the technique for 2 weeks. If unused, the bonus fades. A technique with a Personal range cannot be nullified.
Bloodline Feats
Battle Ready (Sharingan Eye) [Meta-Chakra]
You are quick in activating your Sharingan Eye in battle.
Prerequisite: Advanced Bloodline (Sharingan Eye), Sharingan Eye +2.
Benefit: The character may spend 1 meta-chakra charge to activate the Sharingan Eye ability as a swift action.
Darkbane Sharingan
Your mangekyou sharingan evolves into its perfect form.
Prerequisite: Advanced Bloodline (Sharingan Eye), Mangekyou Sharingan, Sharingan Eye +6, Spot 27 ranks.
Benefit: The character can activate his Mangekyou Sharingan an additional 2 times per day safely, and gains a low-light vision and a darkvision 60 feet while it is active. The mangekyou sharingan always appears to be activated, though additional bonus aren't granted. The character does not suffer mangekyou sharingan blindness penalties from using techniques (but still may from overuse of the ability), and can use mangekyou sharingan techniques even when the mangekyou sharingan isn't activated. The character heals an additional point of mangekyou sharingan blindness per cycle of rest.
Special: The primary way of obtaining this feat is by absorbing another pair of mangekyou sharingan eyes. Doing so allows the character to immediately gain both of the previous mangekyou sharingan's host's mangekyou techniques (see mangekyou sharingan feat, below).
Mangekyou Sharingan
Through effort and powerful blood, you unlock the ultimate Sharingan Eye.
Prerequisite: Advanced Bloodline (Sharingan Eye), Sharingan Eye +4.
Benefit: Selecting this feat enables you to learn two of the following techniques:
Amaterasu, Kamui or Tsukuyomi, and you become able to learn the genjutsu Magen -Kyouten Chiten. You gain the mangekyou sharingan.
Special: The GM may require the character to accomplish some deeds in order to be able to select this feat (such as the assassination of a beloved one, for example).
Mangekyou Sharingan (Su): The character can activate this power as a free action that does not provoke an attack of opportunity only when his sharingan eye is active. For 2 rounds, the character's sharingan eye and offensive foresight gain an additional +1 bonus. Additionally, he can See Chakra without needing to concentrate and is able to See Through Chakra while concentrating. The mangekyou sharingan can be used up to once every five levels every day. Each use after the fourth grants the character 1 point of mangekyou sharingan blindness.
Mangekyou Sharingan Blindness: Overuse of the mangekyou sharingan and use of certain techniques gives the character mangekyou sharingan blindness. Each point is cumulative, and has an effect depending on the number of points currently afflicting the character. Mangekyou Sharingan blindness is treated as ability damage, and heals at the rate of 1 point every 72 hours. Because the strain is so high, mangekyou sharingan blindness will not heal until all other temporary damage has been mended. Complete bed rest doubles the amount of mangekyou sharingan blindness healed. Characters that accumulate 10 points of blindness are permanently blind and cannot be healed naturally. Characters that have become blind may restore their vision through transplanting their eyes with a sharingan "donor," through divine intervention, or through the use of specialized technology. The penalties are shown on the table below, and are all negated while the mangekyou sharingan is active.
TABLE: MANGEKYOU SHARINGAN BLINDNESS
Ninja's Mimicry
Using your keen and insightful Sharingan, you are able to pierce through your enemy's technique and copy them.
Prerequisite: Advanced Bloodline (Sharingan Eye), Sharingan Eye +2
Benefit: You gain the Sharingan Technique Mimicry special ability.
Partial Sharingan
Your ability at maintaining the Sharingan activated for a long time improves further,
enabling you to keep your Sharingan activated, to some extent, most of the day.
Prerequisite: Sharingan Eye +4, Genjutsu 18 ranks, Ninjutsu 18 ranks, Taijutsu 18 ranks
Benefit: You gain the ability to partially activate your sharingan eye. In this state, the Sharingan Eye only grants half its standard bonus, rounded down (maximum +3), and you cannot use any abilities relevant to the sharingan eye (such as offensive foresight, glare, or high speed sight). You may perform still techniques requiring the sharingan to be active, activate the mangekyou sharingan (bonuses from the Mangekyou Sharingan do not count towards the maximum +3 sharingan eye bonus), use technique mimicry or concentrate to See Chakra. The cost of partial sharingan is 3 chakra per round instead of 6.
