Arthur knew he didn't need to act.
Beside him, Sylvaris, who had been silently observing the exchange, moved with lightning speed. The massive serpent interposed itself between Arthur and the demon, its emerald scales shimmering as it coiled defensively.
The demon's claws collided with Sylvaris's body, sparks flying as dark energy clashed against the serpent's tough hide. Sylvaris hissed, its fangs bared, and its long body coiled tightly as it absorbed the blow.
Sylvaris was an Epic-Grade Boss, just like the demon, but he only held a slight advantage. Not only was he two levels higher than the enraged creature, but Sylvaris also had the benefit of being Arthur's summon, which made him immortal as he would always be summoned back after a day had passed.
The impact forced Sylvaris back slightly, the sheer force of the attack proving that the demon wasn't weak. But Sylvaris held his ground, his body tensing as it pushed back against the demon's assault.
