Yes, it's damage is divided among each one, though you can just make a singular dragon. And yes this basically has the parasite attached to it and once it makes contact with an opposing technique; the parasite attaches to it etc. As long as you want yes, and yes, but it doesnt need to just be basic 5 - can be the combined ones/AE as well. If no more questions, here's the next one:
(Inton: Namakemono no Ude ) Yin Release: Hands of Sloth
Type: Supplementary/Offensive/Defensive
Rank: S
Range: Short – Mid
Chakra Cost: 100 (110 w/ YY: Hands of Sloth) -50 per turn
Damage: 120
Description: This technique gets its name from one of the deadliest sins, Sloth. The user begins by clapping their hands and focusing their Yin Release chakra behind them, creating several chakra arms (up to 8) behind them, each of which is spiritual in nature. The arms themselves are invisible to the naked eye, but they can be sensed by external forms of chakra sensory or Doujutsu. The arms are capable of physically interacting with the world and attacking or defending against physical constructs. However, the user can freely turn them intangible if they wish to bypass these physical obstacles. The base usage of this technique allows the user to attack or defend covertly by freely manipulating the invisible arms. However, in their second form the user can add the “properties of sloth” to the hands which are dejection, idleness, and sleep. Dejection is a loss of will and focus translated in causing a victim to lose coherent perception of the world around them and weaken their ability to defend against genjutsu. Idleness is a loss of action which is translated to a hampered ability to cast techniques. Sleep is a loss of consciousness which is translated in a comatose state brought about by the sealing of one’s spirit if they are not sufficiently healed. The third and final form of this technique is brought about when the user introduces their Yang Release chakra which essentially makes the hands quasi-sentient and self-sufficient without the user’s mental input.
Note: All Yin Release users can use the base form of this technique. Yin Release Specialists or Yin-Yang users can use the second form. The final form of this technique can only be used by Yin-Yang users with a Yin affinity.
Note: The properties of sloth are spiritually degenerating properties. The more a victim interacts with the hands the worse they become. When touched by the hands once, the victim enters dejection and becomes unable to deduce A-rank and above genjutsu and unable to break S-rank genjutsu by any means. When touched twice the victim enters idleness and they become unable to perform techniques within a single time-frame. When touched thrice, the victim’s mind is sealed over the course of 2 turns and they enter a genjutsu that renders them a mindless puppet to the user. The properties of sloth can only affect victims if the hands are tangible. Switching between tangibility and intangibility requires a move.
Note: Genjutsu specialists and other Yin-Yang users can resist the properties of sloth through the use of counter genjutsu or Yin Release techniques like Yin State.
Note: This technique can be used once per battle. While in use, the user cannot use any non-elemental ninjutsu, Yang Release, or Yin-Yang Release techniques.
