Haki/Kenbunshoku Haki

Kenbunshoku Haki is a form of Haki that allows the user to sense the presence of others, even if they are concealed from view or too far to see naturally as shown by Silas. With enough skill, one can use this Haki to predict an opponent's moves shortly before they make them, thereby making the attack that much easier to evade. This prediction appears to the user as an image or brief "premonition" of what the opponent will do in the user's mind's eye, and the damage the user will take if the attack actually "hits". It appears that the more killing intent the enemy has, the easier they are to predict. Although, more skilled users can predict future moves whether there are ambient murderous intents or not.
