"Haahhk!!"
A decent amount of blood creates a crimson arc in the air as it makes its way down to the ground.
Rex trudges through the inky darkness of the forest, desperately seeking a clearing where the moonlight can grace his blood-drenched body, tattered with gruesome wounds. He pushes onward, straining with every step, searching for scarce moonlight in the castle's direction.
It was hard to navigate with his blurred vision, he has lost too much strength and blood.
Looking down at his mangled chest and amputated arm, Rex gritted his teeth, trying to force in the urge of roaring in agony. His regenerative powers were being outpaced by the waves of wicked energy that surged through his body. He stumbled forward, fighting the torment that threatened to overwhelm him. 'My healing... it's too slow,' he thought desperately.
Definitely the doings of the Executor's power that had rendered his self-healing ability greatly.
