HumanAIController calculates the "dangerousness" of an enemy based on the largest amount of damage received from it (assuming it's larger than the attack values of the enemy's limbs). Meaning that an enemy that inflicted lots of damage to the character using items is considered dangerous even if it has no attacks assigned to it's limbs.
