Elementalist

Elementalist is a job class that hailed originally from YGGDRASIL.

Background
According to Narberal Gamma, Elementalists are listed as arcane magic casters that specialize in the use of a particular element. In other word, all sorts of elemental damages done with spells were counted as magic attacks. For hybrids between magic caster and warrior, it can also be counted as physical attacks if the weapon they are using is elemental. According to the Pleiades, further specialization within a specific elementalism can be made such as in the case with Evileye's use of crystals. While so, other elementalist types ranged from aspects like acid, poison, gravity, and so on.

In the New World, there once existed a nation called Inveria, who were said to be practitioners of the four great systems which was also known as the Four Elemental traditions. Each one of their country's magic casters are known to specialised in a specific element. Particularly, people possessing Rainbow Eyes tended to be gifted at the traditions, which would lead them to enter the appropriate magic using professions in the nation.

Meanwhile, other countries such as the Re-Estize Kingdom and the Baharuth Empire, believe in the Four Elemental Gods religiously.

Abilities and Powers
Since Elementalists mainly focuses on one element they specialized in, this means their attack power increases greatly. However, at the same time, they are also said to be quite weak and vulnerable outside their area of expertise elementally. Ainz noted no matter how powerful a specialist was, one could not prepare to resist all elemental attacks. However, by focusing on specific resistances, a character could make themselves immune to elements to which they should have been weak to.

According to Shalltear Bloodfallen, the only way to discern a person's elemental weaknesses was to use the [Life Essence] spell to check their HP and barrage them with attacks of multiple elements, then see whichever one hurt them the most. However, that method only works as long as the foe doesn't use the [False Data: Life] spell ahead of time. When elementalists use elemental attack spells on foes weak against a particular element, they would be affected by status effects or debuffs. For foes not weak against such elements, they will end up having immunity as long as they have items, innate elements, resistances to ward off its effects.

Including Super-Tier Magic and Metamagic Enhancements like Maxmimize Magic, the higher the tier level for an attack spell of an element ascends, the greater the elemental damage it can further sustain to foes who are weak against it. While their exact resistances varied between type, every high-level being be it demons, undead or humans had their very own strong elemental resistances respectively.

According to the Web Novel Counterpart of Rigrit Bers Caurau, even if one can’t defeat the power of an Elementalist who specialized in elements such as Earth, one can still go out of their way to exploit the foe's elemental affinities and compatibilities to turn the tables in one's favor.
