The sword landed in the heart. This was Abel's style. He would not give his enemy a chance to strike back.
In regards to the head wolf rider captain on the left, Abel flashed a white magic pattern on his Ancient Pledge shield and unleashed a shield strike towards him.
The magic pattern struck the head wolf rider captain and blasted it directly off his mount wolf along with the momentum of the shield. He landed on the ground, helplessly paralyzed for 2 seconds.
By that point, the 2 spears of those other 2 head wolf rider captains at the back were also approaching Abel. Although they saw their 2 teammates in the front failing badly, it was not that easy to stop an attack that relied on the momentum of their mount wolves like that.
Abel had his iron sword inside the heart of that head wolf rider captain on his right, so it was on its last legs. However, those worgens were born with a strong life force. They would fight until they lost their last breath.
