Introduction: Some of the information came from other people while the others are based on my opinions. The pictures came from youtubers since i don't have all classes that has a class gem you will find the names of the youtubers below they deserve the credits for the pictures

What are Class Gems-Class gems are gems that are different from other empowered gems and normal gems.These kinds of gems augments one of the ability of a class.Also this gem can't be equipped by another class as this is class-locked 

Class Gem key-In order to find these types of Gems you will need a class gem key which requires 3 things namely 

*5K and above Power rank

*The specified Class

*Everdark

So where do we get these keys?-You can get them at empowered gem boxes which can be purchased from the Shadowy Market it cost 1 lunar soul to buy one so hold on to your hopes while opening these boxes as the keys are uncommon

Class Gem Abilities-So moving on to the new abilities or augmented abilities of the class we will start in

Shadow Hunter Class gem

The Shadow Hunter's class gem is named *Shadow blitz gem* It's Basic attack becomes a rapid-fire stream of arrows. Dealing damage to a shadow-marked enemy consumes the mark and triggers an explosion.Basically it turns the shadow hunter's normal attack speed into a minigun attack speed also a good addition to this is you don't even need attack speed stat on gears you can change them to movement speed if you like Shadow-marked enemies when hit triggers an explosion causing an aoe it's not a regular AOE if the damage is 1m it would do the same damage to others which is pretty strong

Boomeranger Class Gem:

The boomeranger's class gem named is *Bawk-Bomb* This augments the Big Bomb to  Bawk-Bomb when used 3 chickens will came out. It it similar to the Mysterious urn ability but a guaranteed chickens its also possible to have 6 or more chickens though making boomeranger's a more stronger class that it was before

Revenant Class Gem 

The Revenant's class changed is called *Aegis Assault* in which the Bulwark Bash Or his m2 skill loses his cooldown (which can be spammed) and applies a stacking damage but no longer taunts In my opinion this gem is kinda useless since Revenant is a tank not a lunar lancer because he loses his taunt ability. However some people still use the gem as for fun or a physical type revenant

Lunar Lancer Class Gem

The lunar lunar's class gem (will put a name to this later) Augments his passive lunancy when the passive triggers it will summon a clone of a lunar lancer dealing damage to the enemy

Candy Barbarian Class Gem

The Candy Barbarian's class gem is named *Scoop n Gloop* it augments his 1 skill (sugar crush) It is similar to the Spirit Storm of a revenant in which he pulls his enemies towards them and crushing them. This gem makes the candy barbarian tankier than ever 

Neon Ninja Class Gem

The Neon Ninja's class gem is named *Heuristic Hackstar* in which it replaces the normal shuriken with a massive buzzsaw that passes through enemies, damaging every enemy in its path and applying Stasis Blade. NN's new augmented ability deals a massive damage when it triggers a critical

Dracolyte Class Gem

When a Burnt Offering detonates, it has a chance to spawn a mini Dracolyte minion that attacks enemies for a brief duration. This augmented ability is similar to that of a lunar lancer difference is it's not a clone and very uncommon to spawn a small dragon

Fae Trickster Class Gem

The Fae trickster's class gem is nmaed *Faerocious Facsimile* in which Blink decoys are no longer immobile; they close on enemies and explode on contact, dealing damage and stunning enemies.

 

Gunslinger Class Gem 

The Gunslinger's class gem is named *Overcharged* in which it removes the attack speed effect of the run and gun ability but replaces it with max charged shots which is actually strong too it's might be a little slow but it's strong

Knight Class Gem

The Knight's class gem is called *Spirit Squire*It Charge no longer propels you forward. Instead, a Spirit Squire charges forward through multiple enemies, dealing damage and stunning them.

Chloromancer Class Gem 

The Chloromancer's class gem augments his M2 skill or leafy lasher in which there's a random chance to spawn a machinegun plant which again similar to dracolyte's small dragon it has a uncommon chance of spawning too and can be hard to distinguish from other plants

Ice Sage Class Gem 

The Ice sage's class gem changes his M2 skill or Ice crash to a blizzard skill where he shoots 3 projectiles at once  Hitting an enemy will give a debuff that gives a 35% chance (75% if defeated) to spawn a ring a projectiles around the enemy that damages other enemies.

Pirate Captain Class Gem

The Pirate Captain's class gem augments his M2 skill or first mate in which before he can only summon one cannon but thanks to the class gem he is now able to summon 2 cannons while in battle making pirate captain another strong class

Tomb Raiser Class Gem

The Tomb Raiser's Class gem changes his 1 skill or banshee's boon in which having a 75% reduced damage from enemies the class gem changed this to summon a real banshee that heals minions and attacks enemies It's similar to the lunar lancer skill because the banshee is like a copy of Tomb raiser but with a draining hp
