Yup it's one the perfect examples of how Yang has destructive affects on others and not only Yin. You can really get a lot of mileage from it, namely like how Daemon made his Yang CFS with viruses etc. Anyways, moving onto the next:
( Yoton: Jigoku no Enjin ) - Yang Release: Ring of Hell
Type: Supplementary
Rank: S
Range: Short
Chakra: 80 for touch based version/100 for ranged version
Damage: N/A
Description: By channeling copious amounts of Yang energy, the user is able to infuse others with this, temporarily enhancing their physical attributes. This is achieved in two ways, either by direct touch or proximity. The first is more limited to a single person but has greater benefits; those channeled directly into will be able to reduce 35 damage from physical contact and gain physical alterations to their body that the Yang energy 'breathes' into life, such as twice the height or width of their body, additional arms or legs, etc as long as within reason and used solely for physical purposes. Should the user use the alternative release, then he is able to release Yang energy from his body up to Long range away, affecting all allies in the range. This variant allows the user to augment all allies with the same type of changes, ranging from all gaining wings to more. These changes only last a limited time, however; after 3 turns pass, the grown appendages or changes fall and revert back to normal. Depending on the alteration, one of a few benefits might be obtained.
Note: If additional arms, stronger arms or alterations related to the arm are made, then the target will gain an additional +20 to Taijutsu. If the changes target the head, the user is able to grant a 2x tracking. If leg based alterations are made, then the target will gain either +4 levels to his base speed or +20 damage to leg based tai. If changes target the torso, then an universal durability boost of B rank Ninjutsu immunity is obtained and if wings or similar is created, then the user is able to fly at thrice their speed.
Note: The damage and speed boosts are considered Passive and Base Speed increases. The values listed in the techniques are if the touch based variant is used. If the ranged variant is used, then these benefits are reduced by gained on a lesser scale ( +15 to Tai instead of +20, +2 Speed Levels, 1.5x Tracking, or -15 from all physical clashes).
Note: Touch based variant can only affect up to two people per event. Ranged variant creates a wave of Yang energy that affects up to 3 allies and lasts up to 4 turns.
Note: Can only be used three times in total.
