Damian searched all corners of the limited area again and again, and finally, deep into one of the earth cracks, he found a dark chunk of rock. It wasn't a rock—it was the mineral called magnetite. He could extract iron from it, but Damian had better plans for it. He put the ore on top of the highest rock formation and, using 60% of his mana pool, weaved a powerful lightning spell.
The massive lightning fell directly upon the magnetite, even blackening it and breaking it into smaller chunks.
But when Damian gathered all the chunks, he smiled like a maniac. It was a success.
He had a magnet—over three solid small chunks of it, even. There were lots of different metals mixed in it, including iron, so Damian picked the other non-magnetic pieces and extracted iron particles from it. Just from this one rock, he had gathered more iron than he would have in 20 days of separation from the dirt.
