Diagonal Movement

The first diagonal square counts as 5 feet, but the second diagonal square counts as 10 feet. This pattern of 5 feet and then 10 feet continues whenever you're counting diagonally, even if the creature moves straight between different bits of diagonal movement. For example, a character might move 1 square diagonally (5 feet), then 3 squares straight (15 feet), and then another square diagonally (10 feet) for a total movement of 30 feet.
