Werden's Illagers +

A half-Vex, half-Evoker abomination, Sinister is a formidable foe wielding three devastating abilities:

Charge: Like the Vex, Sinister charges at its target with blinding speed, dealing swift melee damage.

Summon: Sinister summons three Disorders, a half-Vex, half-Allay abomination. These creatures charge at you, dealing damage and stealing items from your inventory.

Curse: Sinister inflicts the Illager Curse on its target. This curse causes villagers to flee and refuse trades, while iron golems become hostile toward the cursed. 

If there are Allays nearby, Sinister can corrupt them into either Vexes or Disorders.

If a Vex and a Raider are near Sinister,it will combine them, giving the Raider wings.

When you kill Sinister, there is a 30% chance it will drop a Pale Apple. You can feed this apple to an Allay by shift-right-clicking. Afterward, the Allay will begin to transform. In about 20 minutes, it will become a Pale Allay.

Pale Allays are the combat version of Allays, meaning you can give them weapons to fight. They have three command states: follow, sit, and wander.

Some special items have unique effects when held:
-Blaze Rod – Sets the target on fire when hit.
-End Rod – Teleports the target on hit.
-Fishing Rod – Pulls the target upward when hit.
-Lightning Rod – Strikes the target with lightning when hit (only during thunderstorms).

Also, if you spawn a Pale Allay in Creative mode, you can tame it by using a Pale Apple (taming is only possible in Creative mode).

A dark, faceless Illager that has learned to control shadows. It has three attacks:

Shadow Steal: Shadomancer steals a piece of the target's shadow to summon three mimics around it.

Shadow Portal: Shadomancer opens a portal near the target that pulls in nearby entities. All pulled entities are then teleported to a second portal located 20 blocks above the first, causing them to fall to the ground.

Shadow Tune: Can only be used if the Shadomancer has absorbed at least one Shadow Mimic. Shadomancer summons Shadow Notes around him and each note moves to the nearest raider. Each note a raider receives allows them to dodge one attack

If a mimic dies near Shadomancer, it will absorb the mimic. Each absorbed mimic makes it stronger and faster.

A fusion of Rhino and Ravager, Rhinager is a raider mount built for destruction. Capable of carrying up to two raiders, this beast has three attacks:

Standard Melee: Strong close-range strikes that can knock back targets and disable shields.

Charge (Ram): Lowers its head before sprinting forward at high speed, knocking back and damaging anything in its path.

Slam Attack: Quickly lowers its head and then thrusts it upward, smashing the ground and sending blocks flying in a destructive wave that damages enemies.

Fireologer is a Vindicator who was trapped in the Nether for far too long. Over time, the intense heat and isolation drove him to master the art of pyromancy, abandoning his axe entirely in favor of destructive fire magic. It has 5 attacks:

Sun Laser: The Fireologer channels energy before unleashing a blazing beam of solar fire straight ahead.

Magma Chunk: The Fireologer summons a chunk of magma above its target. Upon impact, the chunk explodes, creating small lava pools that linger and burn anything nearby.

Flame Arrows: The Fireologer rapidly fires a barrage of flaming arrows infused with magical fire energy. These arrows ignite targets and leave small patches of fire where they land.

Flameling: The Fireologer summons small fiery minions known as Flamelings. These creatures swarm targets, setting everything they touch ablaze.

Magma Ball: The Fireologer begins charging a magma ball before launching it at its target.

-Illagers:

Buzzster : A beekeeper illager who has brainwashed bees to serve and fight for it.

Nullifier : A strange, flying, textureless illager that cancels all positive mob effects around it.

Gamer : An illager who plays on a console; it can bring creatures from other games into the world.

-Minibosses:

Liftager : An Illager who has kidnapped a baby End mob known as the Levitathan. Using its powers, the Liftager can levitate enemies or lift nearby entities and hurl them at its target.

-Bosses:

Dreamancer : A sleepy illager that drags its enemies into its dreams where it controls the fight.

Astrocaller : A cosmic illager that calls down falling stars or even summons a giant asteroid.

Eradicator : An ancient, seemingly immortal illager knight that has survived death many times.

Outposter : A living pillager outpost with massive legs.

-Final Bosses:

Reflector : A strange floating device created by illagers using magic. It reflects all incoming damage back at the attacker and can even reflect the environment around it. How can it even be defeated?

Atomancer : An illager whose power source is everywhere. It can extract atoms from anything and merge them to another ones to create things that should not exist.
