Daniel sheathed his daggers quickly and raised his left hand. He drew upon his mana reserves, which were constantly refilling thanks to [Energy Siphon].
"[Mana Bolt]!"
A concentrated sphere of purple magic shot from his palm, streaking toward the Guardian's chest. It was a direct hit.
FPZZT!
There was no explosion. There was no damage at all. The Sentinel simply absorbed the bolt. The purple energy disappeared into its white armor, causing the creature to glow slightly brighter.
"It eats magic," Daniel realized with a jolt of horror. "It draws power from the Core, and it can absorb external energy."
He was literally in trouble. His physical attacks were bouncing off, and his magical attacks were only feeding it. The Sentinel seized the offensive.
The Guardian spun the spear, turning it into a wheel of light, and charged. Daniel ran along the curved wall, trying to stay out of its way, but it didn't let up.
