Grave Fiends

The Grave Fiends only had one objective in their mind, the flesh of Xu Feng. His life force was abundant enough to attract their attention completely.

"The system thinks it outwitted me, but I'll prove it wrong." Xu Feng sneered, sacrificing 10% of his current health, and activated Dark Pact.

Once the Abyssal Phantom was summoned, Xu Feng commanded it to attack the nearest Grave Fiends. 

The Abyssal Phantom growled excitedly as it rushed ahead, slashing its claw at the Grave Fiends. 

However, unlike the previous time, the Grave Fiends' defenses were no joke, and having withstood the claw strike, they quickly retaliated with their Necrotic Strike. 

Necrotic strike was one of the Grave Fiend's skills, allowing them to inflict a damage-over-time(DOT) effect on targets, draining them 150 Health Points(HP) over 10 seconds.
