So if I am a Sage and you are a Kage, that would be the effect. Basically used to cause the opponent to mess up on a hand seal. Remember though, the closer you are, the more effective the Killing Intent would be.If a difference in rank smaller than 2 ranks exist, the enemy will feel only the pressure and the ominous presence of their dark intentions. Its enough to lose your grasp on a weapon or stay clinched to it (depending on the situation) or even to hesitate in an attack, stumble or mess up a handseal, all depending on the situation and proximity. The effect is small and normally not that significant but can be effectively used to pressure enemies into making a mistake.
This would happen if I were a Sage and you a Genin or S-Class, so tread carefully against a more powerful opponent should you be of lower rank. Lastly, Killing Intent can be countered with your own Killing Intent, mind cleansing techniques or pain. So, just ask any questions if you have any, if not, we will continue."If a difference of 2 ranks or more exist, the enemy will be frozen, almost unable to move as the overwhelming killing intent dominates their own conscious and riddles them with nightmarish versions of death. The paralyzation gradually weakens as time passes and can only be maintained while the user is focused on the target. The further away the target, the weaker it is and it can only fully paralyze a target within short range. Similarly, the more targets one focuses on, the weaker the effect is in each one (divinding the effects equally between the number of targets)
