Erik's wings strained against the invisible force of Levium's telekinesis. Every movement was a battle in itself.
"You're tiring, Erik," Uncle Benjamin said. "How long can you keep this up?"
Erik gritted his teeth, refusing to show weakness.
"How long can YOU keep this up? I bet the amount of energy you are using must not be low."
"Don't worry about me. I have plenty of mana left."
Yet Levium was shocked by how well Erik was holding against him in a pure brain-crystal power fight. He must have had similar levels of mana to him.
Erik summoned a whirlwind, sending it hurtling towards his opponent. The funnel of air picked up shards of glass and twisted metal along the way, transforming into a deadly cyclone.
