After the largest explosion of the fight had happened, the area Cain and the creature were fighting each other in had been covered in fire.
There wasn't much damage done since they were on the edge of the explosion but it did cause a distraction.
Using the confusion, Cain closed the distance between himself and the creature and slammed his hammers into its chest.
The creature was flung backwards and rolled along the ground several times. It lifted its head and looked back at where Cain was while roaring at him "Roooaaaarrgghh!!".
Cain had chased after the creature and as it started roaring at him he brought his hammer down on its head.
The creatures head slammed into the ground and Cain continued to attack relentlessly. What followed was a series of attacks numbering in the 20's, each of them hitting the creature in its head or chest.
