"Yes," he nods. "I noticed the same, myself. My magic usually never requires that much energy. I think something must have happened when we fell through...whatever it was we fell through."

"Quite a lot, usually," he says. "Charms, transfiguration spells, enchantments, among others. I'm lucky to have my wand with me, but my magic...doesn't always work here."

"I never know if a spell is going to hit or if it's going to backfire," he admits. "And even the ones that don't work still take a lot of energy."
