[He had considered those options months ago, but shot them all down because he didn't want to become adjusted to a tool that he wouldn't be able to take home with him. It was a refusal to adapt, he knew, but he didn't want to slack on working the only heist that was possible in Luceti. Escape.

However, adaptation might be the best policy. The main reason he hadn't taken up learning the Jitte from Smoker was two-fold. One, Smoker didn't want Lupin using Zenigata's weapon against him, and Two, his hands were his best tool as a thief. While he wasn't afraid to throw a few punches, he didn't want to do anything that was risky enough to cause real damage.

Even with his misgivings, it wasn't a bad idea.

The magic was another tool he had considered, but his conversations with Harry Dresden proved that he was liable to take a scientific approach to the task. The simple trick Harry taught him with the chalk circle was going to face rigorous testing once he found a skilled and open minded person to assist him. But that was simple, borderline mundane, and based on belief in its abilities. Anyone could do it, like the filial magic.]
