Nightcrawler can easily teleport north south along Earth's magnetic lines of force. However, teleporting east west against them or teleporting vertically is more difficult. Under optimal conditions, Nightcrawler can teleport 2 miles east west, 3 miles north south, and 2 miles vertically if he exerts himself.
He also tends to prefer only teleporting to places he can see, or that he knows - so that he does not accidentally teleport himself into something (like a wall or mountain)
