I summarize that the ninjutsu and attack is direct basic damage ... if you attack the enemy ... rl injury works this way. if you attack the enemy sometimes, it comes out red and blue ... but when it comes out red you know that red damage is nin + tai or nin ... when it comes out in blue it means that your injury subtracts the enemy's injury. The result is added to the previous red damage and therefore it comes out blue ... critical ... .. but as I said it is probability sometimes if sometimes not ... but ... but the ninjutsu attacks the resistance ... the ninjutsu is stable I mean you will never lose damage ... while injury is possibility and rounding.
