"Defensive Counterattack" was not effective against the Magic Motion Annihilation Cannon. That was understandable.
The passive "Defensive Counterattack" effect was: After receiving an attack, it would reflect 200% of the damage to the enemy.
The effect of this passive skill required a specific target.
The special attribute of the Magic Motion Annihilation Cannon was that it could not be chosen.
Therefore, "Defensive Counterattack" could not work on the war machinery.
This undoubtedly put some pressure on Occam.
The inability to reflect damage meant that Occam might lose health.
This War Machine could reduce the completeness of the magic array by 5%. From this, one could see how powerful it was.
If this blast hit Occam…
Even if his health and defense were astonishing, it would still be difficult for him to hold on.
Therefore, before approaching the demon army, Occam activated the passive skill "Sacrifice".
