Genjutsu Guide

Just like other types of jutsu, Genjutsus have "attack power" and every ninja has an innate "resistance" to genjutsu which usually looks like this:

Attack power = the jutsu's formula (usually some variation of the Gen stat)

Gen Resistance = Gen stat + 1/2Perception[/i]

Some genjutsus may have a trigger (such as eye contact) and tend to be stronger. Area or multi-target genjutsus tend to be weaker.

Genjutsus with a trigger might be avoided in some way, but most jutsus don't have a trigger thus cannot be avoided, but they can be dealt with:

• A) Damaging the one casting the genjutsu instantly ends it.
  
  
• B) If your gen resistance is equal or greater than the attack power of the genjutsu then the genjutsu fails outright.
  
  
• C) If the difference between your resistance and the genjutsu's attack power is 15 points or less, you can use the "Kai" jutsu do dispel it.
  
  
• D) If the difference between your resistance and the genjutsu's attack power is more than 15 points then it's too late to use "Kai". However, every round you spend under a genjutsu causes your genjutsu resistance to temporarily increases by 2, by 3 if that same jutsu has previously been cast on you by the same ninja. If you wait long enough your gen resistance might increase enough to use option B) or C). Once the jutsu is over gen resistance resets back to normal.
  
  
• E) If it's way too dangerous to remain under the genjutsu and wait for its duration to expire or your temporary gen resistance to build up, then as a last resort you can injure yourself in order to temporarily increase your gen resistance. For every 1 damage you inflict on yourself you gain 2 resistance points.

Awareness That You Are Under a Genjutsu
If the difference between your resistance and the genjutsu's attack power is more than 45 points then you are not aware that you are under a genjutsu thus you can't inflict damage to yourself. Skills that affect the effectiveness of "Kai" also affect this condition by the same amount.

If you have multiple genjutsus on you (from different enemies) then only the one with the highest Gen power affects you. If they are from the same enemy then he chooses which one affects you. A single Kai dispels all genjutsus that would normally fall within the scope of its negating effect.
