Element Reels (エレメントリール, Eremento Rīru?) is a recurring ability closely associated with Wakka from Final Fantasy X. It allows Wakka to fire an attack with his blitzball that is an elemental attack based on inputs.
X Element Reels appears as an Overdrive in Final Fantasy X, and is part of Wakka's Slots as his first available Slots ability. Wakka spins the slots, with the four magical elements: water, fire, thunder and ice. If three similar icons (I.e Fire-Fire-Fire) are lined up, Wakka unleashes a blitzball attack of that element on all enemies. If two out of three are the same, Wakka unleashes one attack at random with this element. If all three are different, Wakka just attacks at random, but with more attack power than a normal attack.
Classical elements typically refer to ancient concepts similar to the modern states of matter: earth (solid), water (liquid), air (gas) and fire (plasma). Classical elements are the simplest form of existence, of everything in existence. Many philosophies and worldviews believe in classical elements.
