Movement refers to a character or monster's ability to move through an area.
Skills now can inherently turn mid-animation, with a wider angle of turning for skills with longer animation times. Additionally, many skills now dynamically move the player forward if targeting far away or have other in-built mobility. Most skills also allow limited movement or turning during the skill animation. Bow skills and certain spells can be used while moving, with an inherent movement speed penalty.
