There are many classes in Nexus Clash - Link here: https://nexusclash.com/

These classes are affected by how good, evil or neutral you are.

At the beginning every character starts off a mortal - and has access only to basic skills to spend their character points on

As one levels up, once when you hit level 10 and spent at least 70 character points on basic skills - you can upgrade class to a T2 class

Again at level 20, and have spent 250 character points, you can again upgrade classes to a T3 class.

List of classes -

T1 - Morality doesn't matter and its the default class which is
Mortal. Basically a normal human


Then you can switch to T2 classes at level 10 and this depends on your morality
Good Morality have
Paladin
The Paladin is an angelic warrior dedicated to goodness whose strength and powers arise from their purity. Those who accept the call to fight for the forces of righteousness are duty-bound to remain Good, lest they lose access to the powers they are allowed to wield. Their devotion to the ideals upheld by the good elder powers allows the Paladin to Smite the wicked and hold fast against the coming darkness.

and

Shepherd
The Shepherd is an angel of mercy and a student of good magic. One becomes a Shepherd by swearing themselves to the Elder Powers of Good. They channel holy magic directly from their covenant with the Elder Powers, and can use that power to purify magic, aid others in need, and even consecrate the land itself.

Neutral have access to
Myrmidon
A Myrmidon has focused on the art of combat while retaining free will, bound to neither Good nor Evil. A Myrmidon has superhuman senses and a pragmatic approach to combat that never turns down an opportunity for victory.

and

sorceror
A Sorcerer is a student of magic who has learned by their own dedication, rather than the tutelage of holy or unholy forces. Sorcerers are keenly aware of the truth that power equals power equals power, and can channel that understanding into means to convert one form of power into another. All Sorcerers are skilled in the arts of magic and can easily learn Spells to give them an edge in battle.

Evils have access to
Pariah
The foot soldiers of Stygia, Pariahs are demonic warriors empowered by the shedding of blood and the rage that burns in their souls. Whether the blood that flows belongs to the enemy or the Pariah, these demons are more powerful the more the blood flows. The fury of the Pariah is so great that even in death these demons may strike down their foes.

and

Defiler
The dark priesthood of demonkind, Defilers are dark sorcerers driven by a yearning for power. Defilers Demoralize and Poison their enemies in battle, and maintain their power through sacrifices dedicated to the Evil Elder Powers. Nothing is safe in the presence of a Defiler, who may help itself to the blood, magic, and spiritual essence of its foe.


Then you get access at level 20 to T3 classes

Good have access to
Holy Champion
The Holy Champion is the living essence of the holy elements of Elysium, a paragon angel who has shed their humanity to become one with timeless truths. The shape and form that the Holy Champion takes may change rapidly based on the tide of battle and the needs of the moment - depending on the circumstances, the Champion may take the forms as diverse as deep waters, a rain of fire, ancient stone or any of a multitude of wondrous living creatures.

Exalted Harbinger
The Exalted Harbinger is a swift hunter and bringer of judgement to the wicked. The embodiment of the four great dooms of Namm, the Harbinger heralds War, Conquest, Judgement and Death.

Seraph
Tasked to protect Angels and the innocent against the Demonic hordes, Seraphs are the shield and sword of the Heavenly Host. Though they give up their human flesh to do so, they receive the sacred machinery of Elysium in order to endure against impossible odds and turn the tide against evil.

Redeemed
A few demons begin down the path of darkness, only to turn back toward the light. Those who walk the path of redemption are blessed with great physical and spiritual purity and the ability to protect others. Redeemed have great zeal in battle against their former kind, and fight to teach others held captive by demonic forces how to be free. Redeemed that were once Pariahs will become self-sacrificing Ex-Pariahs, and Redeemed that were once Defilers will learn to turn their former evil knowledge to good ends as Ex-Defilers.

Advocate
The Advocate is a patron Saint, a celestial benefactor by which the power of the Angelic Hosts is greatly enhanced. These angels have access to far greater benefits from Prayer to their patron Powers, and act as the strategists of the righteous who bestow the blessings earned by their sanctity upon others

Archon -
The Archon is a zealous angelic judge charged by Namm to root out and destroy the unworthy. The Archon is the keeper of secret and ancient Words which they may call upon for greater strength in battle - or project over the battlefield to rain destruction upon demons and other doers of evil.

Lightspeaker
Caretaker of the creatures of the Elysian fields, the Lightspeaker shepherds and guides their charges. While not personally formidable combatants, even a single Lightspeaker can field an entire army of lesser angelic beings as soldiers and healers. The Lightspeaker is wise in the ways of the Nexus' fauna and may bolster allies and turn aside the wrath of enemies.

Neutrals have access to

Eternal Soldier
Master of martial training and discipline, the Eternal Soldier is focused upon utilising superior training, resilience, and tactics to overcome their enemies. The Eternal Soldier relies very little on anything that could be considered magical, but has developed both equipment and their own body into superior weapons.

Nexus Champion
Mysterious warriors who modify their personal reality with tattoos that cover their bodies, Nexus Champions focus on victory through balance and inner strength. The Nexus Champion can learn the ways of magic and has a mastery of the elements sufficient to selectively resist them under the right circumstances.

Revenant
Undead warriors of death and darkness, Revenants have inspired many myths in many worlds, not least of them the Vampire and Werewolf. Revenants take many forms, most of them terrifying and bestial to behold, and in so doing turn the death and ruin of those around them to their gain to sustain their powers.

Conduit
A voyager between the planes and delver into the secrets of reality, a Conduit is the master of magical efficiency and maker of wondrous works. More than any other Class, the Conduit is keenly aware of the intricate workings of reality and can weave change into it for the benefit of their allies and the doom of their enemies.

Elementalist

The Elementalist wields a vast, intuitive command of the material elements of creation. Drawing on a balance of water, fire, earth, air and the essence of life, the Elementalist can alter the land, summon powerful allies, and strike down foes with a potent mastery of magic.

Lich
A seeker after necromantic (death) magic, the Lich has transcended Hashaa's power of decay and become undead through the path first delved by Haldos. No death goes to waste in the presence of the Lich, who exploits the violence and decay around them to build armies, harvest useful components and return from death on their own terms.

Wizard
The Wizard is the master - and architect - of the laws and lore of Magic. Building upon the paths begun as a Sorcerer, Wizards excel at improving spells to a degree far beyond what other Classes would be capable of. Wizards are not restricted solely to spells and may tinker with other, more literal machinery for an advantage in battle.

Evils have access to

Infernal Behemoth
The Infernal Behemoth is the personification of violence, destruction, and death. These bestial combat engines excel at bringing death and destruction to any and all that oppose them while shrugging off all but the strongest of blows. The Infernal Behemoth specializes in close combat and can use their strength to deal out massive amounts of damage. They are able to concentrate their powers to command the fires of hell that burn within them, exerting them outward to wreath their weapons in unholy flame or inward to fuel furious Bloodlust to crush all those who stand in their way.

Doom Howler
A harbinger of destruction, the Doom Howler is a demonic spirit that leaves terror and destruction in its wake. Doom Howlers are elusive wielders of dark magic who drain the will of their enemies and can be terribly difficult to land a blow on even when cornered.

Void walker
The nightmare that strikes from the shadows, the Void Walker is the ultimate assassin. Able to pass through walls, cloak into invisibility, and even pass through dimensions at a whim, the Void Walker is all but impossible to evade. The Void Walker is skilled at sizing up the defenses of its opponents and adjusting its tactics on the fly to bypass whatever defenses its victim has put faith in.

Fallen
Angels who have once embraced the light and then fallen into the depths of evil are known as the Fallen. These fiendish beings embrace the pursuit of the Seven Deadly Sins in a twisted mockery of the Angelic order they once followed. In the presence of a Fallen, Angels may suffer doubt and even feel separated from their patron Powers. Fallen that were once Paladins will become relentlessly violent Ex-Paladins, while Fallen that were once Shepherds will poison and sacrifice their victims as Ex-Shepherds.

Corrupter
The demonic penchant for twisting deals and usurping power is never more evident than in the Corruptor. These insidious demons are able to turn nearly anything that their opponents bring to battle against them, whether magical power, potent weapons or summoned creatures. A Corruptor is never far from a source of power that can be drained and flung at the enemy as magical might.

Dark Oppressor
The nobility of demonkind, the Dark Oppressor is a power broker, a binder of deals and a builder of empires. These demonic hierarchs ensure loyalty with wondrous rewards and deadly curses, always seeking an advantage that will earn them more followers and more favor from the Dark Powers.

Wyrm Master
Warped and twisted by gazing into the twisted mind of Tholaghru, Wyrm Masters are grotesquely mutated demons that have a natural affinity for the gibbering hordes of Stygia's creatures. Always experimenting and changing, the Wyrm Master strives to cultivate ever stronger and stranger monsters to hurl into battle against Stygia's enemies.
