Jim was hesitant for a few seconds before he made up his mind. The disciples on the ground were getting killed at a fast pace, and if he didn't move now to ensure his safety then he would be next.
"Screw this," he took out a large piece of ore in one hand. It was pure white with a transparent body that showed deep and irregular thin branching silver veins.

"Why does it feel much different?" he couldn't help but ask.
'You forgot you are already high over the ground,' the old man explained, 'it's normal for gravity here to be much stronger than down there.'
"Oh, will that strengthen my spell then?"
'I believe so.'
