Truth be told, out of the 48% HP that they had taken off, 10% of it was the additional ‘bonus’ provided by the {Glare of the Death God}. This would indirectly mean that Zhang Yang and his party members were only capable of reducing 38% of the boss’s HP bar in an hour! Based on their current performance, the boss would still have 14% HP remained on him when Zhang Yang’s {God of War Transformation} wears off!
By then, Zhang Yang should be able to use another {Glare of the Death God}. As long as it takes effect, they should still stand a chance at bringing the HP bar of the boss down to 4%.
