New Illagers

Illusioner
The Illusioner is a bow-wielding mob that can apply an invisibility effect and create several copies of itself to disorient the player.
Spawn: Woodland Mansions, Fortresses, and Raid Omen bottles of level 3 or higher.

Enchanter
The Enchanter is a mob that generally does not attack the player directly. Its main purpose is to strengthen its allies using enchantments.
For example, it could increase the movement speed of allies or increase their attack damage.  However, these effects should only last for a limited amount of time to maintain game balance.
Spawn locations: Woodland Mansions, Fortresses, and Raid Omen bottles of level 2 or higher.
Shield Pillager
This is a Pillager equipped with a shield and a sword. Its main purpose is to attack players while also protecting its allies. I think this type of mob could make combat more interesting.
Spawn locations: Pillager Outposts, Fortresses, Pillager Mines, and Raid Omen bottles of level 1 or higher.
 The Shield Pillager can block attacks from the player. However, if the player attacks it with an axe, its shield will stop protecting it for a short period of time.
Pillager Rider
This is a Pillager riding a horse and equipped with iron armor. Its weapon is an iron spear.
Spawn: Pillager Outposts and Raid Omen bottles of level 2 or higher.
The Pillager Rider attacks players at high speed, attempting to hit them with its spear. It can also defend itself with a shield. When using the shield, the damage it receives is reduced.
