The Dark Souls series is known for being extremely difficult. This is because of the complexity of the combat and the strength of the enemies in the game. When fighting an enemy, the only way to dodge its weapon is to perform a tuck and roll. The tuck and roll is the core of all combat in Dark Souls. It gives you a small window of invincibility which can be used to re-position yourself behind an enemy or give you just enough time to drink a crucial health potion. At first glance however a tuck and roll looks painful, but when examined closely it can be seen why a tuck and roll is a genius use of physics and the human body in order to mitigate pain. When jumping from a building, all of the force will be exerted upon your feet and legs when landing which is extremely dangerous. If you tuck and roll however, the force will be dispersed evenly across your body, allowing you to jump from distances that you couldn't before. This move is used by people who do Parkour, or freerunning.
