I’m not going to practice teleportation magic on a moving train, because I like being able to breath, but the book was helpful. It was just a lot of reinforcement of what teleportation is, I could do instant teleportation, but I never was good at those types of spells. However, Portals? Yeah, that’s my thing. I’m super good with portals. The portal magic I use to enter my pocket dimension is similar, but I still have to imagine the place I’m going to enter.
