Animalia is only a B-ranked technique and your wording of the technique itself isn't even half as ambiguous as you're making it sound. You're taking too many liberties with what the jutsu is capable of doing...this is, of course, unless you've edited it. Otherwise I don't believe most of the things you described animalia to be able to do can actually do. Please explain that to me[/spoiler]
( Genjutsu: Hyakujuu ) Illusion Technique: Animalia
Rank: B
Range: Short-Mid
Chakra Cost: 20
Damage Points: N/a
Description: By preforming 1 handseal, the user is able to cast an illusion where the opponent will
1.feel a
2.great amount of animals of any
3.chosen size, within some limit , around himself. The illusion will manifest itself as
4.body parts, whole animals,
5.living or dead,
6.attacking the user or standing still. While it can create
7.any animal, it is more frequently used to summon animal specimens of
8.one's summoning contract. Blood can be added to further reinstate the realism of the illusion.
It's all about the key words.
1. Ambiguity of the word, denoting any sort of sensory manipulation to meet the "feel" bar. Allowing, thus, a choice between any of the senses, or all of them.
2. Thus allowing you to create more than 1 animal, without limiting yourself to a specific one.
3. Allows any sized animal. Prior to what's in the description, I had a differentiation between normal sized animals and Boss sized animals, which the moderator noted could be brought down to any size with a single usage.
4. Allowing you to choose how much of the animal you present, be it an entire fully functional animal or merely an animal part, a shell, a leg, a teeth, or a combination of them. That, plus 2. allow you to create a great deal of animal parts, thus a number of teeth is entirely within range.
5. Allowing you to choose how you present an animal, in it's full health form or deceased form, and any range of health between that, as you're the one drawing the illusion. Since you can already make any body part, you could just create a skeleton animal, for instants. From that, and from the 1. part, you could create an illusion of taste of an animal that died on the grill.
6. Allowing you to animate your illusion in any way you want. Adding all the previous properties, why not have a bunch of teeth that form a mouth, bitting the opponent. Why not have an electric eel that shocks your opponent? Why not have a walking skeleton? Why not make a replica of your opponent's animals crying of pain?
7. Any existing species, any brand, any race, any age, any gender.
8. Any fiction animal, any body modification, any chakra, any property and, most importantly, any replica of existing animals.
But yeah, B rank, I have too many genjutsu for me to keep track of all their ranks. First World Problems.
also I was right in my elemental counter capabilities in regards to the larva. I said 1-rank lower of the elemental advantage meaning, whatever element is used, the opponent needs A-ranked of that element's weakness to purge it from their body. In the case of a neutral element there needs to be 2-ranks higher as the normal rule is 1+ rank but with elements playing into affect it makes it 2+ ranks. This technique being S-rank, there is only one rank higher which is Forbidden therefore this technique cannot be broken with anything else aside from the vantage element of the one used.
Genjutsu kai won't work on this either so the only method is through chakra purge with an elemental full body technique. That is if we're going by Elemental Genjutsu standards.
Nope:
Counters Genjutsu but sacrifices the Jutsu
Weak Element - Forbidden Rank
Neutral Element - S Rank
Strong Element - A Rank
Basic Chakra / Kai - N/A ( higher than Forbidden )
Counter Genjutsu without costing the Jutsu (Comes out weakened)
Weak Element - N/A ( higher than Forbidden )
Neutral Element - Forbidden Rank
Strong Element - S Rank
Basic Chakra / Kai - N/A ( higher than higher than Forbidden)
Any other burst of chakra are incapable of purging the larva, instead hindering the genjutsu slightly, but overall doing no lasting effect on the normal progression of the technique.
