The battle raged on, with Kaelin's magic clashing against the Shadowheart's dark power. Raven struck at the statue with his sword, but its energy shielded it from harm. Lirien watched in awe as the two forces clashed, the air crackling with energy.
Kaelin's magic was a beautiful thing to behold, a shimmering web of light that seemed to pulse with life. But the Shadowheart's power was a dark and malevolent force, a cancer that seemed to spread and grow with each passing moment.
Raven fought bravely, his sword flashing in the dim light of the cavern. But even his skill and strength were no match for the Shadowheart's might. He stumbled back, his armor dented and battered, as the statue's energy surged forward.
Lirien knew they had to do something, but what? She was no warrior, and her own powers were limited to healing and shielding. She glanced around, searching for inspiration.
That was when she saw it – a series of ancient runes etched into the wall of the cavern. They pulsed with a faint, blue light, and seemed to be connected to the Shadowheart's power.
Without hesitation, Lirien rushed forward, her hands reaching out to touch the runes. As soon as she did, she felt a surge of energy flow through her. The runes began to glow brighter, and she could feel their power coursing through her veins.
"Kaelin!" she cried out, her voice clear and strong. "I've found a way to weaken the Shadowheart!"
Kaelin turned to her, its eyes flashing with understanding. "What is it?" it asked.
"The runes," Lirien said. "They're connected to the Shadowheart's power. If we can disrupt them, we might be able to weaken it."
Raven nodded, his eyes gleaming with determination. "I'll take care of the sword," he said. "You two focus on the runes."
With renewed purpose, Lirien and Kaelin attacked the Shadowheart's energy shield. The statue howled in rage as they struck at it with all their might.
Meanwhile, Raven launched himself at the statue once more. His sword flashed in the dim light, striking true again and again. But even as he fought, he could feel the Shadowheart's power growing stronger.
It was then that he saw it – a small, glowing crystal embedded in the statue's chest. It pulsed with an otherworldly energy, and seemed to be the source of the Shadowheart's power.
