The Elementalist (精霊使い, Seireitsukai?, lit. Spirit User) is a recurring job in the Final Fantasy series, and one of the many classes that had their debut in the Tactics Advance series. Like their name shows, they use the powers of the elements in battle.
The Elementalist skillset, Spirit Magic, consists mostly of spells that have a range of three tiles, deal elemental damage, and inflict a negative status effect. Their most advanced ability, Elementalshift, randomly changes the target's elemental resistance. When played correctly, Elementalists can exploit their adversaries' innate weaknesses with a versatile set of elemental magic.
Elementalists remain mostly the same, but they lose the Elementalshift ability from the previous game. However, they gain a new Lightning-elemental spell.
Elementalists can enhance the elemental power of characters' attacks, and shield them from elemental damage. The Elementalist crown halves elemental damage dealt to the wearer.
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.
